<a href="https://www.apartments.com.au/developments/collingwood-vic-3066">Collingwood</a>’s northern edge continues to sharpen its reputation as one of Melbourne’s most compelling cultural precincts, where established creative institutions, leading hospitality, and independent fashion converge within a tightly held inner-city neighbourhood.

Set within this evolving pocket, <a href="https://www.apartments.com.au/new-apartments/derby-street-by-milieu-collingwood-4-derby-street-collingwood-vic-3066">Derby Street by Milieu</a> draws on a location that balances proximity to some of the inner north’s most influential destinations with the quieter, tree-lined character that defines the streets edging East Melbourne. Positioned just moments from both Smith and Gertrude Streets, the address sits on the periphery of Collingwood’s cultural core, offering immediate access without the intensity of its busiest frontages.&nbsp;

[smartcode_project:default project_id=145576 project_image_fid=355945]

Gertrude Street, in particular, anchors the area’s identity as a destination for Melbourne’s leading food, art and fashion. Within a short walk, venues such as Marion, Cutler &amp; Co, IDES and the Builders Arms Hotel define a tightly curated dining scene with enduring citywide appeal, complemented by a strong fashion and retail presence including Havn, Le Labo and a selection of independent boutiques.

Nearby, institutions such as the Australian Print Workshop and Collingwood Yards sustain a constant rhythm of exhibitions, performances and creative output, embedding art and culture into the everyday fabric of the neighbourhood.

Smith Street, running parallel, extends this offering with a broader mix of hospitality and nightlife, maintaining its status as one of Melbourne’s most active inner-urban strips.

Beyond these high-energy streets, the immediate surrounds shift in tone. Derby Street and its neighbouring blocks are defined by low-rise heritage terraces, mature trees and a settled residential character. Fitzroy Gardens and Carlton Gardens are both within walking distance, alongside the Royal Exhibition Building and Melbourne Museum, bringing together green space and cultural landmarks within minutes of home.

[smartcode_project:default project_id=145576 project_image_fid=355985]

Connectivity remains a key advantage. The CBD sits within easy reach, accessible by tram along Smith Street in around 20 minutes, while also remaining close enough to walk or cycle, supported by the inner north’s established bike network.&nbsp;

<a href="https://www.apartments.com.au/developers/milieu-property">Milieu</a>’s long-standing connection to Collingwood underpins the project’s approach. With a portfolio that includes multiple nearby developments across Bedford, Peel and Napier Streets, the developer brings a sustained understanding of the area’s character and evolution. Derby Street continues this trajectory as a collaboration with award-winning Melbourne-based <a href="https://www.apartments.com.au/architects/studio-bright">Studio Bright</a>, marking the practice’s first multi-residential project in the inner north and reflecting a shared focus on design integrity and contextual response.&nbsp;

Balancing connection to the neighbourhood with a sense of seclusion and refuge, Derby Street by Milieu embodies a level of care and craft typically reserved for single residential projects. Comprising 22 residences across six storeys, with two to four-bedroom configurations priced from $1.15 million, the project is currently under construction with completion expected in late 2027.&nbsp;

A rare new apartment development in the Blue Mountains is the latest in a string of State Significant Development Applications submitted through the New South Wales Government's Housing Delivery Authority.

A total of 270 apartments are being proposed for the 1.16-hectare site at <a href="https://www.apartments.com.au/new-apartments/blue-mountains-alpine-retreat-142-150-narrow-neck-road-katoomba-nsw-2780">142–150 Narrow Neck Road in Katoomba</a>, a parcel of land adjoining the former Katoomba Golf Course. The site was acquired for $3.85 million in 2021 by private developer VDM Prime.

The apartments, comprising a mix of serviced apartments, affordable housing, and traditional build-to-sell product, will be spread across eight low-rise buildings, along with a separate building for a new restaurant, arranged around a green spine that leads to a central park.

<img alt="Katoomba" data-entity-type="file" data-entity-uuid="ee9a2072-f465-44f1-9076-80c9c8ecca02" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-04-22%20at%209.20.21%E2%80%AFAM.png?VersionId=4bT0vQ7j_syl65wcrJmHGm3m5pTvwrY_" />

The Urban Design Report by Atlas Urban says the vision is to create a "contemporary mountain precinct that is responsive to its escarpment landscape, heritage character, and community context."

"The development responds to the current housing supply and affordability challenges identified under the NSW Housing Delivery Authority (HDA), providing a balanced mix of standard, affordable, and short-stay accommodation," the report noted.

"By introducing a variety of dwelling types and tenures, the proposal supports intergenerational living, local workforce retention, and greater housing choice within an area constrained by topography, heritage, and environmental protections."

Of the 270 units proposed, 52 will be serviced apartments. The remainder will comprise 54 studios, 121 one-bedroom units, 39 two-bedroom apartments, and four three- to four-bedroom residences.

<img alt="Katoomba" data-entity-type="file" data-entity-uuid="f704508d-1bdf-4170-955d-0256652402a7" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-04-22%20at%209.56.49%E2%80%AFAM.png?VersionId=TzarHMO4gTOsblCqsbJQkvMqWj9nu2Au" />

The Design Report, by VDM Prime and appointed architect Antoniades Architects, noted that the design seeks to "provide a built form outcome that is highly considered, respectful and contextually fitting, whilst contributing positively to an evolving precinct."

"The site offers three frontages and the opportunity to provide a meaningful interface with the public domain environment. the design has a sympathetic response to streetscape and the green open space that surrounds the site."

The report states that the buildings are broken up to establish an appropriate bulk and scale, emphasised through height and setback strategies and defined through articulation that supports the transition of precinct granularity. It also notes that a central communal open space is established through the site to enhance the social dynamic and access to amenity, including natural ventilation and light to the apartments. The east and west frontages receive solar access during the morning and afternoon, whilst maximising views to the green open space.

The site adjoins the recently completed Yarrabee Katoomba development, comprising 24 duplexes that were completed last year and sold through McGrath Projects.

The relatively new Housing Delivery Authority pathway established by the NSW Government allows developers to submit State Significant Development Applications through a fast-tracked state process, effectively reducing reliance on local council approval pathways and aiming to accelerate housing delivery across New South Wales.

First look: Nearly 300 apartments pitched on former Katoomba golf course site

In Melbourne’s established inner east, the qualities that define a traditional house, width, height, and access to open ground, are increasingly difficult to replicate in new residential developments. Larger landholdings are scarce, and with them, the ability to create apartments that extend beyond compact, internalised layouts.&nbsp;

In <a href="https://www.apartments.com.au/developments/kew-vic-3101">Kew</a>, where the residential fabric is shaped by generous setbacks and mature tree canopies, that tension is especially visible.

<a href="https://www.apartments.com.au/developers/ricdanic-investments-pty-ltd">Ricdanic</a>&nbsp;is bringing forward a boutique collection of just 13 residences across two buildings at 9–11 Wimba Avenue, Kew. Comprising six homes at No.9 and seven at No.11, the project sits on a quiet, tree-lined street just off Cotham Road.&nbsp;

Each apartment has been planned with a level of independence more commonly associated with standalone dwellings, balancing privacy with the efficiencies of apartment living.

Architect Chris Idle, who has been practising for over two decades, says projects like this don’t come along often.

“There are very few opportunities to do these kinds of developments in leafy, established suburbs,” he explains. “To get this level of amenity, natural light, and architectural freedom in such a setting is extremely rare.”

[smartcode_project:default project_id=140755 project_image_fid=366267]

The internal planning begins with width. Living areas extend beyond five metres, allowing furniture, circulation, and glazing to sit comfortably within the same zone without compression. Ceiling heights shift from three metres through to five metres in select areas, changing the sense of scale as you move through the apartment. These proportions are paired with double-glazed windows and fully electric systems, balancing volume with performance, supported by a 7.2 NatHERS energy rating.&nbsp;

From the main living space, the apartments open directly outward. Large sliding doors connect to private gardens averaging 125 square metres, with some residences also incorporating balconies of around 60 square metres. Rather than acting as secondary outdoor zones, these areas sit flush with the internal floor level, extending the usable footprint of the home and allowing for multiple modes of use, whether for quiet daily routines or larger gatherings.&nbsp;

The landscape, led by <a href="https://www.apartments.com.au/landscape-architect/john-patrick-landscape-architects">John Patrick</a>, reinforces this relationship. Across the site, 23 different plant species have been introduced, including a mix of native and established varieties, arranged to maintain privacy while preserving sightlines and light access. Gardens are not treated as decorative buffers but as functional extensions of the apartments, shaped to accommodate movement, seating, and informal use over time.&nbsp;

[smartcode_project:default project_id=140755 project_image_fid=366265]

Architecturally, the project draws from Kew’s historic residential language. Handmade bricks by Krause define the exterior, grounding the buildings within the material palette of the suburb, while interior finishes, stone, timber flooring, and restrained detailing, continue this approach internally. Architect Chris Idle describes the intent as long-term rather than stylistic: “We wanted it to feel timeless.”&nbsp;

This emphasis on durability extends to how the buildings are accessed and secured. Entry is managed through keyless systems, with a double-gated basement incorporating number plate recognition for vehicle access. Each residence is paired with a private lock-up garage accommodating two to three cars, alongside storage, while all entry points are monitored continuously. These measures sit alongside EV readiness and fully electric infrastructure, aligning the project’s operational systems with its long-term design outlook.&nbsp;

The setting remains central to how the development is experienced. Located within walking distance of Kew Junction and close to established schools including Carey Grammar and Xavier College, the address benefits from existing infrastructure while maintaining a residential quietness that is increasingly difficult to find at this scale.&nbsp;

Construction is being delivered by <a href="https://www.apartments.com.au/builders/sinjen">Sinjen</a>, with a 10-year structural guarantee, with completion targeted for mid-2027.

High-end Sydney developer&nbsp;<a href="https://www.apartments.com.au/developers/abadeen-group">Abadeen</a> has secured approval for one of its latest Mosman projects, one of the first developments approved by Mosman Council under the NSW Government’s Low and Mid-Rise Housing Policy.

The approval represents an important step in delivering well-considered housing next to established village locations on Sydney’s Lower North Shore, in line with the intent of the Low and Mid-Rise zoning framework. 
&nbsp; 
There are currently 13 other sites lodged within Mosman Council under the policy, with <a href="https://www.apartments.com.au/new-apartments/27-29-heydon-street-mosman-nsw-2088">Heydon Street</a> among the first to receive development consent. 
&nbsp; 
Abadeen Founder and Executive Chairman Justin Brown said the project reflects a considered and appropriate response to its planning context. 
&nbsp; 
“This approval demonstrates how carefully considered, design-led development can align with the objectives of the Low and Mid-Rise Housing Policy," Brown said.

"The scheme has been designed to respond sensitively to its village setting, with a built form, scale and level of amenity appropriate to its local context. The determination reflects a balanced and considered planning outcome, with Council recognising the capacity for this site to accommodate additional housing within a well-located and established precinct.”

<img alt="Abadeen secures first approval under low and mid-rise housing policy for Heydon Street, Mosman" data-entity-type="file" data-entity-uuid="92811ce3-02e8-44fc-996e-c61ae039bd3e" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Heydon%20Street%20Aerial.jpg?VersionId=ZHJVuWQT64QcdrFJx963pFWFzTX7lI2I" />

The Heydon Street approval followed extensive consultation with Mosman Council, with Abadeen working closely with Council throughout the assessment process.

The approved scheme comprises 27 residences, with only four per floor, creating a low-density living environment. The building will include four half-floor penthouses designed to capture views across Middle Harbour, Sydney Harbour and the surrounding district.&nbsp;

The project is expected to appeal to downsizers and owner-occupiers seeking house-like proportions, privacy and local convenience. There will be north-facing Middle Harbour views from the second level upward. It is also just a flat 100-metre walk to Bridgepoint Shopping Centre, which will appeal to owner-occupiers and in particular downsizers.

Two-bedroom residences are expected to be priced from $1.99 million when sales launch later this year. 
&nbsp; 
Joe Tack, CEO at Abadeen, said the outcome reflects both the quality of the site and the broader need for well-located housing. 
&nbsp; 
“This is a highly considered site within a highly established local setting, offering elevated views and strong connectivity. The project has been designed to respond to that context, delivering a scale and quality of housing aligned with both the planning framework and evolving market demand.” 
&nbsp; 
“This approval is particularly significant in the context of Mosman, where new housing supply has historically been limited. While it represents the first approval of this scale in Mosman to be achieved in over 50 years, it is importantly located within a well-established residential location, in close proximity to the established commercial amenity of Spit Road and Mosman Village. It reflects strong confidence in Abadeen’s approach to design, delivery and community integration, while contributing to the delivery of much-needed housing in a highly constrained market.”

Abadeen has an established track record across Sydney’s Lower North Shore, with recent completions including KOYO in Crows Nest and ENSO in Neutral Bay.

In Mosman, Abadeen recently completed The Hampden, with Mosman Residences on the corner of Spit Road and Clifford Street scheduled for completion later this year. Construction has also commenced at Burran Residences, comprising three full-floor ultra-premium homes positioned just 50 metres from Balmoral Beach, with residences expected to achieve prices in excess of $20 million. Two further projects are also progressing through planning within the local government area.

Apartment developer <a href="https://www.apartments.com.au/developers/martello">Martello™</a> is one of the latest entrants to the Gold Coast development market, with its debut project set to be one of the most boutique offerings on Chevron Island in recent years.

Martello has unveiled <a href="https://www.apartments.com.au/new-apartments/aere-chevron-island-18-20-mawarra-street-chevron-island-qld-4217">Aere Chevron Island</a>, a collection of 33 large-scale two-, three-, and four-bedroom apartments across an 18-storey building on Mawarra Street.

[smartcode_project:default project_id=143932 project_image_fid=367517]

The developer has placed a strong emphasis on wellness, briefing architecture firm Raunik Design to embed this philosophy into the project. It is a direction <a href="https://www.apartments.com.au/developers/martello">Martello™</a> plans to carry through its future developments along the coast.

<a href="https://www.apartments.com.au/developers/martello">Martello™</a> has positioned Aere as a continuation of its human-centric development approach, with a focus extending beyond amenity to the fundamentals of layout, natural light, and spatial planning. Promax Construction has already been appointed to deliver the project, with construction expected to commence in the coming months as part of the group’s broader expansion into South East Queensland.

Rising above the low-rise fabric of Chevron Island, Aere’s design emphasises generous internal proportions and uninterrupted outlooks, with residences oriented to capture coastal, skyline, and waterway views. Interiors prioritise open-plan living, with large-format glazing and carefully considered transitions between indoor and outdoor spaces.

[smartcode_project:default project_id=143932 project_image_fid=367508]

The upper levels are dedicated to larger-format homes, including four-bedroom residences designed as half-floor offerings. These layouts prioritise separation between living and sleeping zones, along with increased privacy and storage, features more commonly associated with detached housing than traditional apartment product.

Aere’s private resident amenity spaces centre on wellness. A rooftop level will incorporate a heated swimming pool, sauna and spa, alongside a residents’ lounge, dining areas and barbecue spaces, while additional shared facilities throughout the building include a gym and yoga area.

The inclusion of both social and quieter retreat spaces reflects a broader shift in higher-end apartment design on the Gold Coast, where developers are increasingly responding to owner-occupier demand for buildings that support long-term living rather than short-stay use.

[smartcode_project:default project_id=143932 project_image_fid=367814]

Aere is positioned within walking distance of Chevron Island’s village centre along Thomas Drive, as well as the HOTA cultural precinct via the Green Bridge, connecting residents to parklands, galleries, and event spaces.

For <a href="https://www.apartments.com.au/developers/martello">Martello™</a>, Aere represents the first in a series of planned Gold Coast developments, with the group also exploring opportunities in other coastal precincts, including Kirra and Palm Beach.

The move north comes as sustained population growth and infrastructure investment continue to reshape South East Queensland, with developers increasingly targeting boutique, design-led projects in established lifestyle pockets. Aere’s relatively small scale and emphasis on spatial quality position it within this emerging segment of the market.

Grenfell Tower

GUEST OBSERVER
As the saying goes: 
<ul>
<li>there are the things that you know; </li>
<li>the things that you know that you don’t know (the known unknown); and </li>
<li>the things that you don’t know that you don’t know (the unknown unknown). </li>
</ul>
The recent Grenfell Tower fire tragedy in London highlights the potential catastrophic consequences of failing to find out the unknown unknown things and/or failing to take action to appropriately deal with the necessary things once known, such as the condition and performance standards of the materials in the building along with the necessary maintenance obligations of the body corporate.
There has been considerable media attention around the widespread existence of non-conforming building materials and potential devastating ramifications for bodies corporate. This article is aimed at the practical and proactive steps which bodies corporate can take to empower themselves and protect their lot owners and residents.
It is certainly true that the effective maintenance of strata title buildings is a complex affair. The contracts for the construction of the buildings on scheme land are entered into between the developer and the builder, long before the lot owners are ever in the picture. This means that; the lot owners have no input into the selection of materials or the standards of construction, and they are often unaware of the location of essential documents for the proper administration of their schemes, including construction contracts, plans and specifications.
This means that the body corporate and lot owners inherit the building with often unknown building materials; unknown latent conditions and they are unaware of the maintenance requirements for their particular building. This also has a direct effect on effectively budgeting for the future expenditure to properly maintain the building in order to maximise its effective lifespan.
Add to this the fact that there is a high amount of change within bodies corporate, which exacerbates the difficulty in managing vital information about the building. Lot owners sell, body corporate managers can change from year to year, resident managers can sell their management rights and committees often change each year. What this means is that the collective knowledge of all of the people who have been involved in the building is rarely centralised and as a result, key information and documentation is often misplaced along the way or is never obtained in the first place.
We recommend that bodies corporate take control of their information and documentation by implementing a building management document or plan. By the committee working in with the body corporate manager to create a bespoke plan for the operation and management of their building, bodies corporate will be able to identify what they know, what are the known unknown things about the building, and what unknown unknown things about their building (which are generally discovered by expert reports and professional advice). Additionally, this information is to be documented and centralised so that the body corporate does not lose this information as lot owners, body corporate managers, resident managers and committees change over time.
As part of the process of creating the building management plan, it is essential for bodies corporate to know the current (point-in-time) status of their building and documentation. For this reason, we highly recommend engagement of an expert, or team of experts, to enable the body corporate to “catch up” on the history of their building by obtaining all necessary documentation and obtain a status report as to the condition of their building as at today. This information and documentation can then be included in the building management plan and future obligations and expenditure for the building can be informed by this information. Additionally, all new occurrences at the building can be recorded in the building management plan as time goes on so that committees have the information which the need to effectively act on behalf of the body corporate to make decisions within their authority and to properly inform the lot owners in order for them to make effective decisions at general meetings.
Building condition and maintenance is only one of the many things which we recommend is included in an effective building management plan. If bodies corporate know what they know, know what they don’t know, and find out the unknown unknown things, then they are in a much greater position to plan for and make effective decisions on all matters which can have an effect on their building.
Hopefully, such an approach can enable bodies corporate to minimise or prevent financial and physical disasters.

Combustible cladding is just one of many essential building owners issues: CK Lawyers

<html><body>
London’s Grenfell Tower fire has prompted the Victorian government to set up a the taskforce to speed up the investigation into how widely flammable cladding has been used on high-rise buildings in the state.
The Victorian Cladding Taskforce will be jointly chaired by former premier Ted Baillieu, who is also an architect, and former deputy premier and minister for planning, John Thwaites, according to the Real Estate Conversation.
The taskforce will comprise of representatives from Worksafe Victoria, the Metropolitan Fire Brigade, the Victorian Building Authority, the Municipal Association of Victoria and Emergency Management Victoria.
Leading strata management body Strata Community Australia (Vic) has welcomed the government move.
But it said in a media release that flammable aluminium cladding was just the ‘tip of the iceberg’ and the taskforce’s terms of reference must be widened to address unsafe glass panels, and other materials risking lives. 
The Grenfell Tower fire in June killed more than 80 people, and stoked up the fire safety issue around high-rises, both in England and in Australia. 
British audits have revealed 120 high-rise buildings use cladding and insulation similar to that installed at the Grenfell Tower.
In 2014, aluminium composite cladding, similar to that used on the Grenfell tower, was found to have contributed to the spread of a fire at the Lacrosse building in Melbourne's Docklands.
Strata Community Australia had earlier expressed concerns that hundreds of apartment and unit complexes in Victoria may be underinsured.
“The underinsurance of apartments and units could be catastrophic, potentially resulting in millions lost for property owners,” it said.
Commenting on the taskforce, Victorian Minister for Planning Richard Wynne said: "We’re bringing together the key agencies to better detect and address the issue of materials used in a non-compliant way.”
A separate stakeholder reference group, including the building unions, the Master Builders Association of Victoria, and the Housing Industry Association, will also be created, the Real Estate Conversation reported.
The taskforce will be set the mandate of inspecting thousands of apartment blocks built in the last 12 years, but instead of inspections focusing on just one material, Strata Community Australia (Vic) is pushing for the taskforce to make these visits a ‘done once, done right’ experience. 
“The news of thousands of buildings receiving government funded inspections and testing in Victoria is excellent progress, but the building defects crisis unfortunately is not isolated to one material alone,” its general manager Rob Beck said. 
With the growing popularity of glass panel facades and cladding, the threat of substandard products of this variety coming into the market rise too and should prompt quick action, added Beck.
“Similar to the recent Grenfell fire regarding flammable aluminium cladding, we must not wait until a glass panel explodes on a couple sitting on their balcony, or falls to the street below crashing down onto pedestrians.
“There is ample information to suggest this is a problem right now, and we are eager to see these high risk materials dealt with at the same time as flammable cladding, not after.” 
He also said it was not desirable to expect Victorian property owners to bear the expense for remediation “while those causing the issues escape any penalties”.
Though there were no deaths in the Lacrosse Apartments blaze, the owners last year served a $16 million dollar bill to rectify the building, roughly sitting at $40,000 per owner, he said.

The fire at the Grenfell Tower in London has naturally led to speculation about the causal factors and the potential for it to happen in Australia.
Understandably, some have raised questions about the role of building products and the extent to which they contributed to fire and its spread.
It is understood that authorities in London will undertake extensive inquiries into the Grenfell Tower tragedy and it is appropriate to let these run their course. As is the norm, Australian authorities will no doubt monitor these inquiries and make improvements to local laws if appropriate. A 2014 incident at the Lacrosse Tower in Melbourne caused authorities to carry out inspections on building products used in the construction of similar buildings to ensure products were fit for purpose.
The relevant laws we have in Australia are comprehensive and under almost continuous review.
Recent changes to the ABCC laws, for example, gave the Office of the Federal Safety Commissioner a bigger role in monitoring building products used in construction projects funded by the Commonwealth Government. The issue has been on the agenda for various COAG committees, including the Building Ministers Forum.
Master Builders and our members understand the importance of ensuring building products are fit for purpose and installed correctly, but there is always a risk that some products entering Australia don't meet minimum requirements.
Everyone in the building supply chain including manufacturers, importers, and wholesalers, retailers, building designers, builders and contractors have a shared responsibility to ensure building products are safe and fit for purpose.
While the focus is often on builders, greater attention should be given to those involved in importation and distribution. Making sure these products don't enter the Australian market in the first place is a position that Master Builders has made clear in submissions to government and other inquiries.

London apartment tower fire and possible issues in Australia

GUEST OBSERVER
Despite the horror of the fire at Grenfell Tower, UK regulations for tall buildings are ahead of the curve in comparison with other countries.
There have been huge improvements in construction materials and technological solutions throughout the modern era. And testing and certification methods have became even more rigorous, to ensure the quality of new products.
Of course, many people are now asking what more could have been done to prevent the tragic loss of life in the Grenfell blaze. The truth is, while architects and engineers can work to mitigate the risk of fire, it cannot be completely eliminated. The addition of some materials to buildings, such as cladding, will obviously now come under scrutiny. But there are several improvements that can be made to old 20th-century tower blocks like Grenfell, to make them safer places to live.
When it comes to managing the risk of fire, builders and architects are guided by three simple principles: prevent risk, evacuate users and minimise damage – in that order. But updating or “retrofitting” older buildings to meet modern safety standards isn’t always straightforward. That’s why architects, builders and other experts work alongside fire engineers to ensure evacuation systems are adequate for the building’s structure, function and users.
There is no single formula. Each building is studied in detail by a design team, which works together to decide what approach is best. It’s important to consider how the building is being used; for instance, while offices are at risk because they contain large amounts of flammable stationary and electronic equipment, in residential units the biggest risks arise from cooking, heaters and other domestic equipment, which can start fires.
Human factors such as forgetfulness, physical limitations and human error must also play a role in fire safety planning – especially when children or elderly people are frequent users. People are also more relaxed at home, which can lead them to lose awareness of some of the risks. People often leave pans on the hob or place heaters near curtains and other combustibles for example. A team must bear all these factors in mind, as they decide how to approach each project: smoke and heat detectors can prevent some accidents, placing sockets away from windows can also help.
Safe evacuation routes
Some buildings rely heavily on evacuation routes to keep users safe when disaster strikes. This requires sound alarm systems, fire barriers in the form of fire doors and walls, and smoke extractors. These features are especially important in historic buildings, where escape routes are narrow or intricate, and have not been designed in accordance with current building regulation standards. Wherever possible, fire stairs should be partly sealed, to prevent smoke from entering, while automatic ventilation systems can be installed, which allow smoke to escape upwards like a chimney.
Done right, this can provide a safe, smoke free escape route. But it is not always possible to achieve this standard in existing buildings, which is why users are sometimes advised to stay in their flats and steer clear of stairs and corridors where smoke can build up. Smoke inhalation is the most common cause of death in fires so residents are often advised to remain in a smoke-free zone and wait to be rescued. It appears this was the case at Grenfell Tower link to stay put.
Likewise, technical considerations can prevent the use of certain types of fire safety technology – for example, when there is no space to accommodate the installation. Installing sprinkler systems is not always feasible because they often require large tanks to store water, which are heavy and need space to allow access for maintenance.
Proper emergency access
It’s hugely important for buildings to be designed to accommodate emergency responses, by making space for fire fighters to take control of and extinguish fires, if and when they occur. Some measures affect the internal layout, such as the installation of fire-fighting lifts. Others relate to the areas surrounding the building and the provision of services. For this reason, large structures must have a water source available, to reinforce the fire brigade’s own supply.
Fire engines can only reach certain heights and cannot cover the upper floors. In new buildings, dry risers are installed, providing an empty vertical pipe which fire fighters can use to pump water up to the higher storeys. In order to function properly, these need to be regularly tested and maintained. They might not be not suitable for some retrofits, due to the lack of space.
Pavements around buildings are often required to be a specific width and strength, to take the size and weight of local fire engines. All of these design measures help fire fighters keeping us safe but they are also highly reliant on maintenance. Residents of Grenfell Tower reported obstructions to emergency access routes, in one of a series of complaints about the safety and maintenance of the building.
Measures to minimise damage
When planning for fires, the team will also try to find ways to minimise the damage to the structure. This is to avoid the risk of collapse, as well as preserve as much of the building as possible, in case it can be reused after the fire.
To do this, the design team can use new building modelling software (BIM) to predict with reasonable accuracy how quickly a fire could spread through a building. All construction materials come with a set of technical data, which designers can input into the software in order to select the most suitable technology and materials for the building.
If a material is highly combustible, then alarm systems become more relevant, while escape routes require better protection and ease of movement. When a building or refurbishment is completed, the designer hands over the key and a maintenance manual to the landlord. Maintenance manuals are very detailed, providing contact information, time schedules and guarantee documents for the upkeep of the building.
A fatal flaw
But even with all these measures in place, there’s still a one major problem: materials are tested in isolation, which means that their technical data does not take into account how they will react when used in combination with other technologies – or when there are human errors in the design or assembling process. These issues are not picked up by BIM software.
Fire can spread rapidly in the small gap between the external face of the building, and the internal walls. Thermal insulation is often placed inside this cavity, and sometimes it is part of the external cladding. Some aluminium panels are made with a rock wool insulation – these are fire resistant. But aluminium gets hot and expands very quickly, heating the insulation layer. If this layer is combustible, fire can spread at speed by travelling through the cavity – which acts as a chimney – producing vast amounts of toxic smoke.
Fire barriers can be used to create compartments within the cavity, installed horizontally and vertically between the cladding and the internal wall at critical points to delay the spread of fire. But this product has to be installed with great skill for it to work efficiently, and it’s not always possible to use it for retrofits, depending on the type and condition of the existing walls.
This explains why, despite all the design efforts, the risk of fire cannot be completely eliminated by design. What’s more, designers and managers can only predict human factors and behaviours to a certain degree. For this reason, communities and schools must work together with designers, fire brigades and building managers to help prevent fires. Meanwhile, building contractors and maintenance professionals must use these techniques to ensure that residents are properly protected from harm.

Grenfell fire aftermath: how 20th-century buildings can be made safer, not more dangerous

GUEST OBSERVER
In the middle of the night, while most residents were sleeping, a devastating fire started at Grenfell Tower in London.
The emergency response was rapid and robust: more than 200 firefighters attended the scene, with assistance arriving just six minutes after the first calls were made. Emergency services have confirmed that 12 people are dead. More remain missing and dozens are injured. Already, people are asking how the fire spread so rapidly and why it was so difficult for residents to escape. 
Doubtless, in time, a thorough investigation will reveal the full details of what caused the disaster. But from an engineering perspective, there are a number of factors in the design of the 24-storey tower block that may have contributed to the speed and scale of the blaze.
Most of the current guidelines across the world contain detailed design requirements for fire safety such as evacuation routes, compartmentation and structural fire design. But Grenfell Tower was built in 1974. At that time, the rules and regulations were not as clear and well-developed as they are now. 
Evacuation and compartmentation
The evacuation route is one of the most important design elements when it comes to fire safety. The route should allow occupants to escape the building as quickly as possible, while sheltering them from smoke and flames. Some tall buildings have staircases installed on the outside to prevent people from getting stuck in the corridors and provide access to fresh air while they escape. Other options include installing high-power fans inside buildings, to clear the evacuation route of smoke in the event of a fire. This feature is included in the design of Dubai’s Burj Khalifa, the tallest building in the world. 
It’s clear that residents were not happy with the fire safety of the escape route from a blog posted in November 2016 and the design below would suggest there was only one set of stairs for evacuation. Investigators will need to determine what evacuation routes were available.

Another key strategy is to correctly design fire compartments to keep the fire from spreading quickly. This entails placing barriers in the building – such as fire-resistant doors and walls – to confine the fire to a local area, or at least slow the speed at which it can spread. These compartments are designed based on the function of the buildings by architects, so residential and commercial buildings will have different compartment design strategies. 
In current design practice, some buildings even include special design measures for fires, such as refuge rooms for occupants in the higher storeys, who could have trouble escaping down stairs. There are also active fire protection methods such as using sprinklers. Though a parliamentary report following the 2009 Lakanal House fire in Camberwell, London, in which six people died, recommended that sprinkler systems be installed in tower blocks across the UK, it’s not clear that these measured were implemented in Grenfell Tower. A local residents action group also claimed that their warnings about a lack of fire safety measures “fell on deaf ears”.
Materials matter
The fire risk level of any building also depends on its structural design – that is, the capacity of its materials to resist fire. Different materials receive different fire ratings in each design. For example, steel buildings are normally required to have structural elements such as beams or columns that can stand for one to two hours with the help of fire protection material such intumescent paint, which swells up when heated to protect the material beneath. 
According to reports, the key structural components of Grenfell Tower are mostly made of concrete – a material which rates highly in terms of fire resistance. While other materials can buckle in high temperatures, concrete structures can help to prevent the collapse of a building in case of fire, as well as making it safer to use helicopters – which can dump up to 9,842 litres of water at a time – to extinguish the blaze. 
There were also reports relating to cladding added as part of an £8.7m refurbishment in 2016. The material used for the cladding was primarily aluminium, which is not fire resistant. What’s more, aluminium has high conductivity – so the cladding itself could have heated up very quickly, failing to prevent the fire from travelling through the windows and up the exterior of the block from one storey to another.
In truth, most old buildings do not conform to the latest guidelines for fire safety design, so it is imperative to update them by installing sprinklers, fire alarms and extra fire evacuation staircases. While those affected may have to wait for some time before the causes of the fire become clear and responsibility is taken, landlords and local councils can act now to help prevent another disaster of this scale from happening again.
