Lewis Land has opened the first completed sky home for inspection at Harbour Shores, giving buyers their first opportunity to step inside one of just three double-storey residences crowning The Waterline.

Each sky home comes with its own private marina berth, rooftop terrace and Broadwater views, combining the scale of a larger home with direct access to the boating lifestyle that underpins the wider <a href="https://www.apartments.com.au/new-apartments/harbour-shores-biggera-waters-564-oxley-drive-biggera-waters-qld-4216">Harbour Shores</a> masterplan.

[smartcode_project:default project_id=113271 project_image_fid=366708]

Lewis Land Head of Development Michael Long said the inclusion of a berth with every Sky Home had become increasingly valuable as marina access across the Gold Coast tightened.

“Marina berths are becoming increasingly difficult to secure across the Gold Coast, so including one with every Sky Home makes this a genuinely rare offering,” Long said.

“The private 70-berth marina will accommodate boats up to 12 metres in length and is positioned just 2.5 kilometres from the Broadwater, placing the open ocean only 15 minutes away.

“Being able to step out of your home onto your boat is a rare luxury, and it’s something residents here can look forward to when it opens later this year.”

[smartcode_project:default project_id=113271 project_image_fid=366709]

The display opening comes as construction completes on The Waterline, with the first residents expected to move in from mid-October.

The three Sky Homes range from 282 sqm to 367 sqm and each feature three bedrooms, three bathrooms, multiple living zones, expansive kitchens with butler's pantries and large balconies taking in the Broadwater outlook.

Each residence also has three secure basement car spaces and additional storage.

“This is the first opportunity the Gold Coast has had to step into Harbour Shores and see, touch and feel what we’re bringing to life here,” Long said.

“There are only three Sky Homes within The Waterline, ranging in size from 282sqm to 367sqm, with each residence featuring three large bedrooms, three bathrooms, multiple living zones, expansive custom-built kitchens with butler’s pantry, and large balconies capturing Broadwater views.”

Residents of The Waterline will have access to a private pool, along with Harbour Shores' wider collection of amenity including a lagoon pool, social clubhouse, tennis court, gym, yoga facilities and sauna.

Lewis Land partnered with Studio Collective to furnish the completed display, with the interiors designed to demonstrate how the residences could function as permanent homes rather than simply as show apartments.

Studio Collective Director Melissa Park said the surrounding waterways informed the interiors, but in a more restrained way than a traditional coastal scheme.

“We drew inspiration from the canals and coastal surrounds, but our approach was to interpret that subtly through layered materials and a grounded palette of earthy tones, rather than literal coastal references,” Park said.

“We introduced hero moments of green and teal to reference the surrounding waterways, while mirrored elements help reflect natural light.

“The result is a residence that feels elevated yet comfortable, somewhere buyers can genuinely imagine themselves living, entertaining and unwinding.”

Sky Homes are priced from $3.65 million.

Lewis Land is also offering private marina berths with The Residences, its limited collection of three and four-bedroom villas positioned directly along the Harbour Shores waterfront boardwalk.

Three-bedroom villas are priced from $2.99 million, while four-bedroom residences start from $3.19 million.

Harbour Shores is being marketed by Colliers International.

Lewis Land opens sky home display as The Waterline completes at Harbour Shores

St Vincent de Paul Society Housing Australia has filed plans for a major mixed-use housing precinct on the southern edge of the North Sydney CBD, adding another significant proposal to a pocket around North Sydn​ey Station that is quickly becoming one of the LGA's busiest development zones.

The State Significant Development Application covers a 5,990 sqm site at <a href="https://www.apartments.com.au/new-apartments/1-19-mackenzie-street-lavender-bay-nsw-2060">1-19 MacKenzie Street and 211 Blues Point Road in Lavender Bay</a>, immediately south of Nor​th Sydney Station and between the commercial core and the lower-rise Lavender Bay Heritage Conservation Area.

Designed by Wardle, the proposal would deliver a new residential tower comprising 88 build-to-sell apartments and 19 affordable apartments, alongside a separate co-living building with 57 rooms and a building manager's studio.

It would also see the significant restoration and upgrade of St Francis Xavier Catholic Church, the adaptive reuse of the former school building, new parish facilities, retail, a new public square and around 1,000 sqm of publicly accessible open space.

<img alt="Vinnies North Sydney" data-entity-type="file" data-entity-uuid="d5dd7f87-a617-463e-b577-17541e01f0e9" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-08-26%20at%209.10.13%E2%80%AFAM.png?VersionId=4R8TsFN3P_LrrXO2HswTOIrx2blil8lh" />

The project is seeking a concurrent rezoning of the site to R4 High Density Residential and an increase in the maximum building height to allow a tower reaching RL120, or up to 20 storeys. The proposal was progressed through the NSW Government's Housing Delivery Authority pathway.

The build-to-sell component will be weighted toward larger apartments, with just six one-bedroom apartments compared with 31 two-beds, 43 three-beds and eight four-bedroom residences.

The 19 affordable apartments will comprise two studios, 15 one-bedroom apartments and two two-bedroom apartments, taking the total apartment component to 107 residences before the 58 co-living rooms are included.

<img alt="Vnnies" data-entity-type="file" data-entity-uuid="7d568ca5-cb90-4e18-96c6-d9795dba0c56" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-08-26%20at%209.10.05%E2%80%AFAM.png?VersionId=GY2R5M9VtQh0EKy1vajaea19PSLOPuRD" />

Wardle's design for the Vinnies site has sought to negotiate that emerging high-rise context while retaining the lower-scale character of MacKenzie Street and the adjoining heritage conservation area.

The main building adopts a three-storey podium and tower arrangement, with the podium aligned to the ridgeline and front setback of St Francis Xavier Church.&nbsp;Wardle has designed the podium with colonnades, seating, recessed entries and active ground-floor frontages, with sandstone-toned precast concrete and face brick referencing the materiality of the existing church.

The tower then steps back eight metres to the south and six metres to the north before rising in a sculpted form comprising four interlocking quadrants. Wardle has also introduced rounded forms and chamfered corners to reduce the tower's perceived bulk and improve view sharing with neighbouring development sites.

Resident facilities and outdoor areas are planned at the separation between the podium and tower at Level 3, oriented toward Sydney Harbour and the CBD skyline.

The tower itself will feature a glass reinforced concrete facade, with recessed balconies and deep reveals used both to provide shading and privacy and frame views toward the harbour and city. The lower levels take a different architectural approach, using brick and sandstone-toned finishes intended to establish a stronger relationship with St Francis Xavier Church. The Church itself will be conserved and upgraded for its continued use, while the former school building will be adaptively reused as part of the co-living component.

<img alt="Lavendar Bay" data-entity-type="file" data-entity-uuid="2d4418ad-90aa-4d49-af93-c80b140aea80" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-08-26%20at%209.09.47%E2%80%AFAM.png?VersionId=Kv4gzbsACaGvZSRuaqcfGC54jEJRXIDJ" />

&nbsp;

The proposal adds to an increasingly concentrated pipeline of residential development around Blue Street, MacKenzie Street and Lavender Bay.

Just west of the site, Central Element lodged plans earlier this year for one of the most significant residential developments proposed in Lavender Bay in recent years.

Central Element's SJB-designed scheme at 64-66 Lavender Street and 3-7 Middlemiss Street would deliver 163 apartments across two towers rising 23 and 32 storeys, replacing five existing apartment buildings containing 32 homes. The project also forms part of the Housing Delivery Authority pathway.

Immediately around North Sy​dney Station, another two significant proposals have emerged at 5 and 15 Blue Street.

Zurich Australian Insurance Properties is seeking to adaptively reuse its longstanding commercial building at 5 Blue Street, directly above North Sydney Station, rather than demolishing the structure.

Its SSDA proposes converting the building into a 14-storey mixed-use development with 62 apartments and 86 co-living rooms, together with ground-floor retail and a major refurbishment of Blue Street Plaza. The application is currently at the Response to Submissions stage.

When the opportunity arose for South Australian developer Palumbo to return to Kent Town, where it had previously delivered East Park Apartments and the East 
Rundle Apartments, it wasn't one the longstanding developer-builder was going to pass up.

The decision was quickly vindicated, with more than 30 apartments sold within the first month of launching <a href="https://www.apartments.com.au/new-apartments/royal-apartments-kent-town-2-8-north-terrace-kent-town-sa-5067">Royal Apartments</a> to the market.

The 206-apartment development, which will bring significant new supply to Adelaide's tightly held eastern city fringe, also gives <a href="https://www.apartments.com.au/developers/palumbo">Palumbo</a> the opportunity to bring new life to one of Kent Town's most recognisable watering holes.

[smartcode_project:default project_id=6109 project_image_fid=376073]

Royal Apartments incorporates the historic Royal Hotel, a venue Palumbo Managing Director Daniel Palumbo said has a longstanding connection with the local community.

"Everyone in the area has history with the Royal Hotel," Palumbo told Apartments.com.au.

"It was quite an active pub and social gathering place for locals. We want to bring it back to its former glory."

[smartcode_project:default project_id=6109 project_image_fid=376072]

The wider development will comprise two residential towers alongside the restored hotel, sitting on North Terrace opposite the Adelaide Park Lands.

For Palumbo, the project also marks a return to familiar territory.

The developer completed East Park Apartments next door more than a decade ago and jumped at the opportunity to develop in Kent Town again when the Royal Hotel site became available.

"The opportunity emerged, and we moved to secure the site," Palumbo said.

"We were approached by the previous landowner, who said they had extensive commitments in Sydney and weren't in a position to deliver the project.

"We took over the site and within six months recut the design scheme to be more in keeping with the type of development we want to bring to Adelaide.

"Now we're on the market and those changes have really resonated with local buyers."

That has translated into a strong start to sales, with 33 apartments transacting in the project's first 35 days.

Palumbo said the early purchaser profile had been consistent with the group's traditional focus on owner-occupiers rather than investor-led apartment stock.

"Local owner-occupiers have always been our market," he said.

"There are always some investors, but we've never developed what would be called traditional development stock. Owner-occupiers are very much our market."

[smartcode_project:default project_id=6109 project_image_fid=376068]

The buyer mix has been diverse so far, with downsizers and younger professionals both accounting for a significant portion of early sales.

South Australia's current stamp duty settings, which allow&nbsp;eligible homeowners in South Australia aged 60 savings of up to $103,830 on stamp duty when they downsize to a new property valued at up to $2 million,&nbsp;have helped encourage downsizer activity, while younger buyers in their late 20s and early 30s have been attracted to the opportunity to live immediately outside the CBD while still being able to walk into the city.



Location has been a major part of the proposition for both buyer cohorts.

[smartcode_project:default project_id=6109 project_image_fid=376075]

Royal Apartments sits on North Terrace directly opposite the Adelaide Park Lands, with residents able to walk through the parklands toward the East End, Rundle Street and Rundle Mall.

Apartments have been positioned to capture views across the parklands, Adelaide skyline, Botanic Gardens and Adelaide Hills.

Palumbo believes the scarcity of developable land along this section of the Park Lands makes the site particularly difficult to replicate.

"There's very few allotments on that side that can be developed," he said.

"If this location was in New York and you were sitting on Central Park, you'd be talking about a $60 million apartments."

Royal Apartments will offer a broad mix of residences, ranging from one-bedroom apartments through to four-bedroom sub-penthouses and penthouses.

Current listings include one-bedroom apartments from $680,000, while larger three and four-bedroom residences are priced around $2.5 million.

Residents will have access to a swimming pool, gym, barbecue and recreation areas, residents' lounge and dining space, and a communal deck.

[smartcode_project:default project_id=6109 project_image_fid=376067]

The apartments will feature generous balconies, while secure parking, bicycle storage and storage cages will also be provided.

A porte-cochère-style arrival and drop-off area has also resonated with buyers, particularly those attracted to being able to walk into the CBD during the day while retaining secure vehicle access at home.

Palumbo is acting as developer, architect and builder on Royal Apartments, continuing the vertically integrated model it has used across its South Australian portfolio.

The group was also behind the $150 million Sofitel Adelaide, the 251-room five-star hotel and residential tower which opened in 2021.

Palumbo said Royal's launch had come at an interesting time for the broader Adelaide apartment market.

Buyer confidence had initially been impacted by uncertainty surrounding the Federal Budget and broader economic conditions, but Palumbo believes sentiment is beginning to improve against a backdrop of significant investment flowing into South Australia.

He pointed to increased activity across defence and resources, including Olympic Dam, as potential long-term drivers of the state's economy and housing market.

"Money is starting to flow into Adeliade, significant amounts as Adelaide bucks the trend of the rest of the country.," Palumbo said.

"There's a lot of activity in the economy over the next decade. I think more investment will come into this market."

Early works on Royal Apartments are expected to commence this year, with major construction activity and cranes anticipated on site from early next year.

Palumbo's return to Kent Town strikes early chord with buyers

Go-to builder-developer <a href="https://www.apartments.com.au/developers/graya">GRAYA</a> is continuing to bulk out its already impressive and diverse apartment portfolio across South East Queensland. Their latest milestone is securing development approval for Silk, its boutique riverfront apartment development in St Lucia.

The approval clears&nbsp;the way for the team to begin construction planning for the 22-residence project.

<a href="https://www.apartments.com.au/new-apartments/silk-st-lucia-16-18-sandford-street-st-lucia-qld-4067">Silk</a> will rise 15 levels from an 810 sqm site at 16-18 Sandford Street, occupying a prominent bend of the Brisbane River with a prized northern aspect across Orleigh Park toward the Brisbane CBD.

The approved scheme will comprise 16 split-floor and six full-floor residences, continuing GRAYA's move into larger-format apartment developments targeting Brisbane's prestige owner-occupier market.

The project has been designed around the site's broad river frontage and dual-direction views, with GRAYA prioritising larger residences, privacy and outlook over apartment yield.

<img alt="Silk St Lucia" data-entity-type="file" data-entity-uuid="aa5c2349-f96c-4914-a812-1f2cd6827af8" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-08-26%20at%208.25.44%E2%80%AFAM.png?VersionId=WY0vEU_7vYjeRJKQHiCwFdMxu8PvFh52" />

GRAYA Co-founder and Chief Executive Officer Rob Gray said the project had been shaped around local homeowners wanting to remain in St Lucia without maintaining a traditional family home.

"St Lucia is one of those suburbs people do not want to leave," Gray said.

"They know the river, the trees, UQ, the golf course, Toowong and Indooroopilly, and that familiarity is hard to replace.

"True riverfront opportunities here are exceptionally scarce. What we have designed at Silk is a way to stay in the suburb people love, with the scale and privacy of a private home and far less to maintain.

"This is not typical apartment product. It is a proper home on the river, and that is exactly what this market has been missing."

The approval comes as new apartment development continues to increase across the St Lucia and neighbouring Toowong corridor, although direct riverfront sites remain considerably more tightly held.

GRAYA Co-founder and Managing Director Andrew Gray said securing the approval had removed a significant element of development risk from Silk.

"Genuine riverfront sites of this quality in St Lucia are not something that comes up regularly," Gray said.

"The approval removes a substantial layer of execution risk, and the location underwrites demand in a way very few inner-city sites can.

"The fundamentals here are as strong as anything we have assessed in Brisbane."

<img alt="Silk St Lucia" data-entity-type="file" data-entity-uuid="d0f3d734-65e1-48e8-8ed3-2e0715ffcdd9" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-08-26%20at%208.25.56%E2%80%AFAM.png?VersionId=sOLSs_jdHkXLWbBKzRyayf5BfTb2vPsD" />

Silk will see GRAYA return to a stretch of the Brisbane River where it already has recent construction experience. The vertically integrated group recently completed ARC in neighbouring Toowong as builder for developer Spyre, delivering the riverfront project on a constrained site.

GRAYA will take a different role at Silk, controlling the project from design and development through construction and aftercare under its vertically integrated model.

The development will include a gym and resident leisure areas at ground level, integrated with the river's edge.

Silk joins a growing pipeline for GRAYA across Brisbane and the Gold Coast, which includes Enclave, The Gallery, Coral and Ripple.

The developer-builder has also recently lodged plans for its largest project to date, <a href="https://www.apartments.com.au/new-apartments/the-silo-19-chester-street-newstead-qld-4006">The Silo</a>, a proposed <a href="https://www.apartments.com.au/news/qld/graya-buys-frasers-newstead-site-plans-the-silo-between-james-street-and-gasworks-precincts">$700 million mixed-use development</a> in Brisbane's James Street precinct.

Silk is expected to predominantly target local owner-occupiers and prestige buyers seeking a permanent riverfront home in Brisbane's inner west.

Registrations of interest are now open, with further details on the project and construction program to be released as it progresses.

GRAYA greenlit for riverfront St Lucia apartment development, Silk

Abadeen has released the whole-floor penthouse crowning its recently completed <a href="https://www.apartments.com.au/buildings/park-residences-cremorne-2-sutherland-street-cremorne-nsw-2090">Park Residences</a> development in Cremorne, bringing the near-300 sqm residence to market for the first time.

Occupying the entire top floor of the boutique Lower North Shore development, the penthouse includes 221 sqm of internal living and a 74 sqm wraparound terrace, with a prized north-facing aspect taking in views across Middle Harbour.

The residence has been completed and fully furnished following a collaboration between Abadeen Executive Chairman Justin Brown and internationally recognised interior designer Jack Freeman, Founder and Managing Director of FREEMAN &amp; CO.

<a href="https://www.apartments.com.au/developers/abadeen">Abadeen</a> and Freeman approached the penthouse as a finished home, sourcing furniture, artwork, lighting and objects from Australia and overseas.

[smartcode_project:default project_id=114246 project_image_fid=378718]

Pieces from Parisian design house Pierre Augustin Rose sit alongside contemporary artworks and bespoke lighting, with Freeman drawing on recent visits to PAD Paris and Salone del Mobile Milano for the final collection.

Brown said the aim was to create a penthouse that felt more like a large-scale private home than a traditional apartment.

"The experience begins the moment the lift doors open. You're welcomed into an elegant dining room before the home opens into an extraordinary living space framed by sun-drenched harbour views.

"Every time someone walks through the front door they pause. It's not just the view, it's the incredible sense of space, the warmth created by the northern sunlight that fills the interiors, and the way every room connects so effortlessly.

"It has all the proportions of a luxury home, while delivering the effortless lifestyle and personalised experience of living in a world-class six-star hotel, combined with the simplicity and convenience of apartment living."

[smartcode_project:default project_id=114246 project_image_fid=378713]

A secure lift provides exclusive access to the penthouse level, opening to a dedicated arrival foyer and dining area before the residence expands into its main living and entertaining spaces.

Floor-to-ceiling glazing runs across the northern side of the home, connecting the interiors with the terrace and Middle Harbour outlook.

The penthouse also features a fireplace and substantial chef's kitchen, while the wraparound terrace has been designed to accommodate both everyday outdoor living and larger-scale entertaining.

[smartcode_project:default project_id=114246 project_image_fid=378720]

Freeman said the interiors had been deliberately kept restrained to complement the scale, natural light and outlook already established by the architecture.

"The penthouse is a serene study in quiet luxury," Freeman said.

"The interior pairs soft, sculptural forms with warm timber, pale stone and a restrained neutral palette. Curated artwork and metallic accents add depth, while abundant natural light creates a calm, effortlessly refined atmosphere. In my world, less is always more."

Freeman said the approach was centred around collecting individual pieces rather than simply decorating the apartment.

"Every material, every object and every piece of furniture has been curated with intention. I am a true believer in collecting versus decorating.

"The architecture already provided extraordinary natural light, remarkable volume and an uninterrupted connection to Middle Harbour. Our role was to complement those qualities with unique one-of-a-kind pieces of fine art and collectible design sourced from recent travels around the world."

[smartcode_project:default project_id=114246 project_image_fid=378694]

Among the collection are solid bronze sculptures by Lorenzo Quinn, alongside a curated crystalware collection and pieces sourced from international design fairs.

Park Residences sits opposite Cammeray Golf Club, Cammeray Croquet Club and Grand Slam Tennis Cammeray, around 300 metres from Neutral Bay Village and its established collection of restaurants, cafés and retail.

Brown said the combination of a whole-floor floorplan, northern aspect and proximity to Neutral Bay was becoming increasingly difficult to find on the Lower North Shore.

"Completed whole-floor penthouses with a sun-drenched north-facing aspect and sweeping Middle Harbour views are exceptionally rare," Brown said.

"Add a quiet position opposite golf, croquet and tennis facilities, a level walk to Neutral Bay Village and only minutes to the CBD, and you have a lifestyle that's incredibly difficult to replicate.

"This is a home that offers the privacy and generosity of a luxury residence together with the convenience of one of Sydney's best-connected harbourside locations."

The penthouse will be exclusively marketed by SRM Residential.

Abadeen unveils penthouse at Park Residences in Cremorne

London Fire

<html><body>
GUEST OBSERVER
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

<html><body>
<img src="https://counter.theconversation.edu.au/content/79518/count.gif?distributor=republish-lightbox-advanced" alt="The Conversation" width="1" height="1">
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.
