One of North Sydney's best-known commercial buildings could become hundreds of new homes, with insurance giant Zurich Australia lodging a State Significant Development Application (SSDA) to transform 5 Blue Street into a mixed-use residential development above North Sydney Station.

Rather than demolishing the existing building and starting again, Zurich is proposing an adaptive reuse project that would convert the landmark office building into a 15-level residential development delivering 62 apartments, 86 affordable co-living dwellings, activated retail and significant upgrades to the Blue Street Plaza.

The proposal reflects a growing trend of commercial property owners repositioning ageing office assets into residential housing as Sydney grapples with housing supply shortages and changing workplace demand.

Located directly above North Sydney Metro and train station, the 3,051 sqm site occupies one of the most strategically positioned parcels of land on Sydney's Lower North Shore.

Designed by fjcstudio, the proposal seeks to retain and adapt much of the existing structure while creating a contemporary residential address that better connects with the public domain surrounding North Sydney Station.

The application proposes two basement levels, ground floor retail, affordable co-living accommodation across the podium levels, and apartments above, while preserving and enhancing the publicly accessible Blue Street Plaza.

Rather than pursuing maximum apartment numbers, Zurich has opted for a housing mix heavily weighted towards larger owner-occupier residences.

The proposal includes 62 build-to-sell apartments comprising 12 one-bedroom, 19 two-bedroom, 29 three-bedroom apartments and two premium penthouses. It also incorporates 86 affordable co-living dwellings, which would be managed in perpetuity by a Community Housing Provider.

That balance between traditional apartments and affordable housing reflects the NSW Government's push to increase housing diversity around major transport infrastructure.

The proposal has been lodged concurrently with a rezoning application, with Zurich arguing the site is ideally positioned to support additional housing given its immediate proximity to public transport, employment and services.

"The proposal aims to respond to the housing challenges facing Sydney through the delivery of diverse housing types in a highly accessible location," the design report by fjcstudio states. It also seeks to improve pedestrian amenity through upgrades to Blue Street Plaza while creating a high-performing residential building that responds to the surrounding context.

<img alt="Zurich" data-entity-type="file" data-entity-uuid="36082e15-c636-4481-bb68-5a5f6443fe39" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-07-22%20at%2010.41.36%E2%80%AFAM.png?VersionId=5P6VD.fvmqjQfIG3TWWMRXxQWiQBjeFB" />

Rather than replacing the commercial building, fjcstudio has developed a design that works with the existing structural framework above the rail corridor, an approach that significantly reduces demolition while allowing the site to be repositioned as a mixed-use residential precinct.

The existing structural constraints have informed much of the building's design, including its relationship with Blue Street and surrounding public spaces.

The building has been designed as a slender tower rising above a clearly defined podium, with vertically expressed façades intended to reduce the perceived bulk while reinforcing North Sydney's emerging skyline.

According to fjcstudio, the architectural language responds directly to the surrounding commercial towers while maintaining a finer grain expression more closely aligned with the neighbouring Lavender Bay streetscape.

The tower incorporates articulated façade elements, landscaped podium edges and recessed upper levels to soften its appearance and improve pedestrian amenity below.

A significant component of the proposal is the revitalisation of Blue Street Plaza.

The existing public space has long served as one of the primary pedestrian connections between North Sydney Station, Greenwood Plaza and Blue Street, yet its role is expected to become even more important following the opening of Sydney Metro.

Zurich's proposal seeks to strengthen that role by improving landscaping, introducing new retail frontages, enhancing pedestrian permeability and creating more active edges throughout the day and evening.

Ground floor retail would wrap the plaza, while separate residential and co-living entries have been designed to improve wayfinding without reducing street activation.

Landscape design has been integrated throughout the podium and public realm, softening what is currently one of the most heavily urbanised parts of North Sydney.

&nbsp;

&nbsp;

fjcstudio has carefully oriented apartments towards Sydney Harbour and the CBD while using privacy blades and articulated façades to minimise overlooking between neighbouring buildings.

Large framed openings along the western elevation maximise harbour outlooks, while the eastern apartments have been angled towards the south-east to improve privacy from neighbouring development.

The project forms part of the continuing transformation of North Sydney from a predominantly commercial CBD into a genuine mixed-use city centre.

Since the completion of Victoria Cross Metro Station, developers have increasingly shifted their attention towards residential projects capable of leveraging the area's unparalleled transport connectivity.

&nbsp;

FiveX recently lodged plans for a 61-storey, 490-apartment tower that would become one of the tallest residential buildings in North Sydney if approved.

Aqualand continues to expand its Lower North Shore presence following the completion of AURA on Walker Street and its recent St Leonards and Roseville proposals.

Developers are also progressing projects throughout Walker Street, Miller Street and the Victoria Cross precinct as demand for well-located owner-occupier apartments continues to strengthen.

Busy developer Aqualand Prestige has formally taken the next step in its expansion across Sydney's Lower North Shore, lodging a State Significant Development Application (SSDA) for its long-held Archer Street site in Chatswood.

The application covers <a href="https://www.apartments.com.au/new-apartments/51-55-archer-street-chatswood-nsw-2067">51-55 Archer Street</a>, a 1,767 sqm amalgamated site on the eastern edge of the Chatswood CBD, where the developer is seeking approval for a 45-level mixed-use tower delivering 114 apartments, including a significant affordable housing component, alongside retail, commercial space and six basement levels of parking.

The SSDA marks the latest milestone for a project Aqualand has been quietly progressing over the past two years. The developer first secured the site for its Aqualand Prestige platform before undertaking an alternative design excellence process with PTW Architects, ultimately avoiding a formal design competition through the Housing Delivery Authority pathway.

The proposal has evolved considerably from Aqualand's original concept. The revised scheme has been designed around larger owner-occupier product, with an unusually high proportion of three and four-bedroom apartments, targeting the more affluent buyer profile, and downsizer, emerging across the North Shore.

<img alt="Archer St" data-entity-type="file" data-entity-uuid="0171204c-5811-41b5-9b09-2335d1b7c3d0" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-07-22%20at%208.52.48%E2%80%AFAM.png?VersionId=6YTuxfq.puZo7k2wbfgemcO5K3QfXYGQ" />

The 114-apartment mix comprises six studios, 27 one-bedroom apartments, 18 two-bedroom apartments, 50 three-bedroom residences and 13 four-bedroom homes. A quarter of the building will be dedicated to affordable housing, well above the mandated 15 per cent&nbsp;

PTW has structured the building vertically, with affordable housing across levels one to six, premium apartments through levels seven to 31, duplex skyhomes on klevels 32 to 43, a penthouse on level 44, and a rooftop plant level above. Six basement levels will provide resident parking and servicing.

The tower is proposed to reach approximately 154 metres, placing it among a growing collection of residential high-rises transforming Chatswood's skyline.

Rather than competing purely on height, PTW says the design has been driven by creating a slimmer tower capable of delivering significantly larger apartments.

"The primary objective of this project was to create a distinctive building that stands out from the recently approved or built structures in the Chatswood area," the design report states, noting the structural efficiency allows greater investment into apartment quality and resident amenity.

Residents would have access to more than 450 sqm of communal open space including landscaped gardens, swimming pool, rooftop entertaining areas, fitness spaces, community gardens, children's play areas and barbecue facilities.

A major focus of the design has been the public domain.

The ground plane has been opened up through landscaped terraces inspired by Willoughby's sandstone ridges, with native planting, public seating, artwork, retail activation and a series of gathering spaces intended to soften what has traditionally been a hard commercial streetscape.

The landscape strategy references Blue Gum forests once common throughout the area, while incorporating Indigenous storytelling, public art and lighting installations to strengthen the connection to Country.

Chatswood has been one of Sydney's busiest apartment markets over the past 12 months, with a steady pipeline of both new project launches and fresh development applications.

Hyecorp recently launched Celine, a 122-apartment development just along Archer Street, while Changfa and Huirong Group are progressing The Anderson, an 84-apartment project on Anderson Street.

Develotek recently secured approval for a 101-apartment tower on Pacific Highway, while Tian An LFD received the green light for Hammond Greens, its apartment development on the edge of the Chatswood Bowling Club.

Commercial property developer FiveX is also making its move into the residential market. Last month it lodged plans for a 61-storey tower with 490 apartments, which, if approved, would become one of the tallest residential buildings in Chatswood.

Aqualand is also expanding its development pipeline following the launch of its luxury residential brand, Aqualand Prestige. The developer has delivered a string of high-end apartment projects across Sydney's affluent suburbs over the past decade, most recently AURA by Aqualand on Walker Street in North Sydney.

[smartcode_project:default project_id=30959 project_image_fid=292863]

It has since quietly assembled its next wave of projects.

Earlier this year Aqualand launched Boronia in Roseville, a boutique 111-apartment development on Larkin Street. The project is one of the first significant apartment developments to launch in the suburb ahead of what is expected to become one of Sydney's most active new housing precincts under the NSW Government's Low and Mid-Rise Housing reforms, which allow greater density around train stations.

[smartcode_project:default project_id=152095 project_image_fid=373685]

The developer has also lodged plans for a two-tower, 413-apartment development on Herbert Street in nearby St Leonards, further strengthening its presence across the Lower North Shore.

Beyond that, Aqualand remains behind the final stage of Barangaroo, where plans will deliver a five-hectare mixed-use precinct comprising new homes, retail, hospitality and community facilities, alongside a new Metro entrance and more than two hectares of public open space, completing the Barangaroo precinct.

Mass timber is becoming an increasingly popular construction material in apartment developments, but Adelaide developer <a href="https://www.apartments.com.au/developers/otello">Otello</a> is taking the approach a step further.

At its new <a href="https://www.apartments.com.au/new-apartments/flowe-bowden-18-gibson-street-bowden-sa-5007">Flowe Bowden</a> development, the exposed cross-laminated timber (CLT) structure isn't just about reducing the building's environmental footprint. It also forms the foundation of a broader wellness strategy, influencing everything from indoor air quality and natural materials to the way residents move through and experience the building.

The 115-apartment mixed-use development, designed by Melbourne-based architecture practice Fieldwork, will occupy a prominent island site opposite Bowden Village Reserve, combining one, two and three-bedroom apartments with retail and a dedicated wellness destination.

[smartcode_project:default project_id=152022 project_image_fid=375528]

Wellness isn't confined to a gym or shared resident facility at Flowe. Instead, Fieldwork embedded the concept into the building itself.

The development has been split into two residential wings connected by a naturally ventilated central breezeway, replacing traditional enclosed corridors with open-air walkways that improve natural light, encourage cross ventilation and create more opportunities for neighbourly interaction.

"Rather than treating wellness as something that only happens on the ground floor, our response integrates it throughout the building, which led us to ask what it really means to design a healthy building," Fieldwork Director Quino Holland said.

[smartcode_project:default project_id=152022 project_image_fid=375531]

The building's architecture also reflects Bowden's industrial heritage. The lower podium references the area's historic brick and sandstone buildings, while the upper levels transition to exposed CLT, allowing the timber structure to become a defining feature throughout the apartments and shared spaces.

The use of mass timber sits alongside a range of sustainability initiatives, including a fully electric, gas-free design, rooftop solar and a targeted 5 Star Green Star rating.

[smartcode_project:default project_id=152022 project_image_fid=375524]

Inside the residences, the focus remains on natural, durable materials. Blackbutt engineered timber flooring, exposed CLT ceilings, porcelain surfaces and warm timber joinery create a calming interior palette, while low-VOC finishes and responsibly sourced materials have been selected to improve indoor air quality.

Kitchens have been designed as the centrepiece of each apartment, featuring porcelain island benchtops, timber-look cabinetry and brushed steel tapware, with layouts that maximise natural light and ventilation.

[smartcode_project:default project_id=152022 project_image_fid=375530]

The more traditional interpretation of wellness comes in the form of Level Eleven, a two-storey wellness club spanning the ground floor, mezzanine and first floor.

The facility will include a gym, yoga and reformer Pilates studios, Finnish and infrared saunas, magnesium hot and cold plunge pools, and dedicated recovery spaces. Unlike many residential wellness facilities, Level Eleven will also operate commercially, allowing the broader Bowden community to access the venue while giving residents exclusive membership benefits.

The ground floor has also been designed around everyday living. A café overlooking Bowden Village Reserve will activate the street frontage, while a bike workshop with tool storage, co-working space and dog wash has been incorporated to support daily routines and encourage interaction between residents.

"Flowe brings together my two biggest passions, creating places and creating healthier lives," Otello founder Daniel Harris said.

"We wanted to create something Adelaide hasn't seen before, a genuinely healthy building, where the way you live is lifted without even trying."

Flowe is positioned directly opposite Bowden Village Reserve and within walking distance of Bowden Railway Station and the Adelaide Entertainment Centre, placing future residents just minutes from the Adelaide CBD while remaining connected to one of the city's most established urban renewal precincts.

Not all apartment amenities are immediately visible.

Swimming pools, gyms, rooftop terraces and residents' lounges have long featured on buyers' wishlists, but as the way Australians live has changed, so too have the features that make apartment living more convenient.

Increasingly, buyers are placing value on the practical aspects of day-to-day life. Fast internet, EV charging, secure bike storage, flexible workspaces and parcel management are becoming just as relevant as lifestyle amenities, reflecting changing habits and expectations.

Online shopping has been one of the biggest drivers of that shift.

Australians spent a record $82.6 billion shopping online in 2025, with almost one in every four retail dollars now spent digitally, making parcel deliveries a routine part of everyday life rather than an occasional convenience.

For apartment residents, however, receiving those deliveries isn't always straightforward.

Without someone home to accept a parcel, deliveries can be redirected to a nearby Post Office, left in building foyers or common areas, or require building management to temporarily store packages. As apartment living continues to grow across Australia's cities, parcel management has become an increasingly important consideration for both residents and developers.

Australia Post's Parcel Locker network is one response to that shift.

<iframe allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen="" frameborder="0" height="315" referrerpolicy="strict-origin-when-cross-origin" src="https://www.youtube.com/embed/KPZ9j5FRdsQ?si=Qztc1dNP3ZvEIUhb" title="YouTube video player" width="560"></iframe>

Rather than relying on home delivery, eligible parcels can be directed to a nominated Parcel Locker, where they're securely stored until collected. Once a parcel arrives, residents receive a notification through the AusPost app or SMS and can retrieve it using a one-time code or QR code at a time that suits them.

The network has expanded to more than 1,500 locations nationwide, with Parcel Lockers positioned at Post Offices, shopping centres, supermarkets, transport hubs and, increasingly, within or alongside residential developments.

That growing presence reflects a broader change in how apartment buildings are being planned.

Developers are increasingly considering the operational side of apartment living alongside traditional lifestyle amenities. Just as secure mailrooms, bicycle storage and EV charging have become more common inclusions, parcel management is emerging as another feature that supports everyday convenience.

It also helps preserve the arrival experience within a building. Carefully designed lobbies and communal spaces can quickly become cluttered when deliveries accumulate, while secure parcel solutions reduce the likelihood of missed deliveries or parcels being left unattended.

For buyers comparing apartments, these everyday details are becoming part of the decision-making process.

Location, floorplans and finishes remain fundamental, but the features that simplify daily life are carrying greater weight than they once did. As online shopping continues to shape consumer behaviour, secure parcel delivery is increasingly becoming another amenity worth looking for.

Parcel delivery is joining the apartment amenity checklist

Inca Property Group has lodged a State Significant Development Application (SSDA) for Dawn, a 53-apartment oceanfront development overlooking Mona Vale Beach.

The proposal, at 35-39 Darley Street East, would replace an existing 18-apartment strata building with a new owner-occupier-focused development comprising 53 two and three-bedroom apartments, including nine affordable built-to-rent residences delivered under the State's infill affordable housing scheme.

Positioned on a 2,679 sqm elevated site around 280 metres from Mona Vale Beach, the development has been designed to maximise panoramic ocean views while responding to the site's sloping topography.

<a href="https://www.apartments.com.au/developers/inca-property-group">Inca Property Group</a> Managing Director Josh Thompson said the State Significant pathway provided greater certainty for projects of this scale.

"This State Significant pathway gives the team real certainty to progress <a href="https://www.apartments.com.au/new-apartments/dawn-35-39-darley-street-east-mona-vale-nsw-2103">Dawn</a> through to completion," Thompson said.

"It allows us to acquire a one-off site, design it carefully and deliver the right offering for the suburb, assessed by the NSW Government's planning department."

The project is one of the first developments in the area to be assessed under the NSW Government's Low and Mid-Rise Housing policy, with the site sitting on the edge of the policy's designated inner area.

The proposal includes three basement levels providing 124 car spaces, alongside a range of resident amenities including a swimming pool, gym, sauna, wellness facilities and private plunge pools for selected ground-floor and penthouse apartments.

<img alt="Dawn" data-entity-type="file" data-entity-uuid="fc1a1daf-0ce4-4f12-9076-b1fa553c7a91" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-07-21%20at%208.42.11%E2%80%AFAM.png?VersionId=4GZ9h.gpNkTljbxyAET8Jfhv51XUamDm" />

Thompson said Dawn had been designed specifically for owner-occupiers and downsizers, a buyer profile that has driven demand across Inca's recent Upper North Shore developments.

"The majority of buyers in our recent North Shore projects have been downsizers, and we are learning exactly what this market is looking for. Beyond the location itself, we have included resort-style amenities to deliver a genuine lifestyle offering," Thompson said.

Located within walking distance of Mona Vale Beach, the town centre, Mona Vale Golf Club and the Royal Motor Yacht Club, Dawn represents Inca's first Northern Beaches project following the sell-out of Tara on Park in Waitara and Ellis Residences, currently under construction in St Ives.

Construction will be undertaken by Inca's in-house construction arm, GOP Constructions.

Dawn is the latest major apartment proposal for Mona Vale, with the suburb emerging as one of the key beneficiaries of the NSW Government's new Low and Mid-Rise Housing policy.

New developer One Living, led by industry veteran Joseph Scuderi, recently secured a site on Mona Vale Road, on the border of Mona Vale and Pymble, where it is planning around 140 apartments.

IPM is also planning its third project in Mona Vale, significantly increasing the scale of its previous developments with an 82-apartment proposal at <a href="https://www.apartments.com.au/new-apartments/159-167-darley-street-west-mona-vale-nsw-2103">159-167 Darley Street West</a>, opposite Bayview Golf Course and less than 800 metres from Mona Vale town centre.

Air Conditioning

<html><body>
EXPERT OBSERVERS
 
It might be blisteringly hot outside, but if you work in an office building, the chances are it’s always reassuringly cool (or cold, depending on your preference) once you walk inside.
In Australia and much of the rest of the world, it’s become standard practice for offices to be cooled or heated to a uniform 22℃. In many Australian offices, this temperature is even officially enshrined in <a href="https://www.propertyobserver.com.au/https://www.emeraldinsight.com/doi/full/10.1108/17561451211211714" target="_blank">commercial tenancy agreements</a>.
And yet temperature is routinely one of the sore points of office politics – many office workers constantly feel too hot or cold at work. Of course, that might simply be because the air conditioning doesn’t work very well where you work. But it’s also reasonable to ask whether 22℃ is really such a magic number after all.
Our review of the available research, <a href="https://www.sciencedirect.com/science/article/pii/S0306261918318233" target="_blank">published recently in the journal Applied Energy</a>, suggests not.
The air conditioning industries certainly view 22℃ as the magic number, judging by guidelines published by the <a href="https://www.rehva.eu/fileadmin/Promotional_material/PPTs/Nr_6_Indoor_Climate_and_Productivity_in_Offices.pdf" target="_blank">European</a> and <a href="https://www.ashrae.org/technical-resources/ashrae-handbook/description-2017-ashrae-handbook-fundamentals" target="_blank">US</a> industry peak bodies. Both claim that office workers’ cognitive performance at different temperatures follows an “inverted U” shaped curve, which <a href="https://indoor.lbl.gov/publications/room-temperature-and-productivity" target="_blank">peaks at 22℃</a>.
<img src="https://images.theconversation.com/files/261648/original/file-20190301-110150-ggyjuv.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="">Inverted-U function between temperature and cognitive performance. CREDIT
This explains why 22℃ has prevailed as the chosen figure all over the world, regardless of <a href="https://www.sciencedirect.com/science/article/pii/S0378778815302632" target="_blank">how much it might cost</a> to heat or cool work spaces to that temperature in different climates. In the heat of an Australian summer this typically involves lots of cooling, but the view is that the prodigious output of comfortably cool workers more than justifies the electricity bill.
But are things really as simple as the graph above would have us believe? To answer that question, we critically reviewed almost 300 studies from a wide range of disciplines including physiology, psychology, ergonomics, neuroscience, sports science, human-technology interaction, and more.
We concluded that the relationship between temperature and performance is not an “inverted U” but rather an “<a href="https://docs.lib.purdue.edu/cgi/viewcontent.cgi?article=1023&amp;context=jhpee" target="_blank">extended U</a>”. The evidence in fact suggests that human performance remains relatively stable across a broad range of acceptable temperatures, but then rapidly deteriorates once it gets any hotter or colder than this. The boundaries of the acceptable ranges depend on a lot of factors, such as the type of task you are doing, how demanding the task is, how adverse the temperature is, how skilled and motivated you are in doing your task, to name just a few. Our previous research found that workers <a href="https://theconversation.com/chill-out-a-slightly-warmer-office-wont-make-it-too-hot-to-think-93789" target="_blank">perform just the same at 25℃</a>, for instance.
<a href="https://images.theconversation.com/files/261600/original/file-20190301-22837-ii9h2v.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/261600/original/file-20190301-22837-ii9h2v.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a> Extended-U relationship between temperature and cognitive performance. CREDIT, Author provided
This is because humans are not just simple, passive machines. We can adapt in all sorts of ways to moderate levels of thermal stress. Common ways of <a href="https://www.sciencedirect.com/science/article/pii/S0378778897000534" target="_blank">adaptation</a> include behavioural adjustment, physiological acclimatisation, psychological habituation, and probably most important of all, expectation adjustment.
So it turns out that our brains can still be at their sharpest even if it’s not exactly 22℃. But that’s not the only reason why the magic temperature is a myth. The existing rationale conflates “cognitive performance” with “office productivity”, when in reality these are two very different things.
“Performance” is a person’s ability to produce “goal-directed activity”. In performance science, a job or task is often broken down into different performance components, such as memory, concentration, logical thinking, executive function and so on. “<a href="http://soh.iums.ac.ir/uploads/0415237920_95689.pdf" target="_blank">Productivity</a>” is the extent to which an organisation is progressing towards its systemic goals, whether that be the amount of products they sell in a year, or the number of customers served within a specific period of time and how satisfied those customers are with the quality of service they received.
But there is no standard way to <a href="https://www.propertyobserver.com.au/https://www.emeraldinsight.com/doi/abs/10.1108/14630010710845730" target="_blank">quantify office productivity</a>. The common practice is to use performance measures as a proxy for overall productivity, but this is problematic for several reasons.
The first is that simulated performance tasks do not accurately represent the nature of real work carried out in actual workplaces. Standard cognitive tasks testing your memory, concentration and vigilance performance might not faithfully capture your ability to generate useful contribution towards achieving your company’s goals.
Second, productivity can also depend on many factors besides workers’ ability to perform. These might include workplace culture, organisational structure, job security and satisfaction, workload, management style, and personal factors such as injury, loss of sleep, life events, health and well-being, or financial stress. Distracted, disgruntled or worried workers aren’t going to be very productive, regardless of what the office temperature will be.
There are practical implications to this. Office managers might be wasting money chasing the “best” temperature for maximum productivity while ignoring other factors that have a much larger bearing on it.

Why the 'perfect' office temperature is a myth

<html><body>
Air-conditioning giant Daikin has secured two new industrial trade centres, in Brisbane and the Gold Coast, just before the onset of the summer season.
Daikin had tasked Savills to assist with finding suitable facilities.
The deals were negotiated by Savills’ Shaw Harrison and Callum Stenson.
Both of the new Daikin stores open this month, with the Brisbane store located at 1/210 Robinson Road in Geebung totalling 710 sqm, and the Gold Coast store located at 26 Lawrence Drive in Nerang totalling 809 sqm. 
It will pay a combined rental of $263,750 per annum.
Daikin has committed to a three-year lease on both properties.
“While Daikin were particularly specific with their requirements we identified well over 20 suitable locations after conducting an extensive market search,” Harrison said.
The Geebung property was vacant prior to Daikin signing the lease, and the property owner assisted with renovating the building to suit Daikin’s showroom fit-out requirements. 
“The main road frontage along Robinson Road was exactly what they were seeking for their Brisbane display centre, with other trade-based industry users also located along this busy strip,” Harrison said.
The newly constructed Nerang facility in the Gold Coast was being marketed by GC Commercial after the previous tenant was involved in a major fire which required the building to be completely rebuilt.

As the weather heats up, Australian households won’t just be cranking up the air conditioning for themselves. Some households will be turning it on for their dogs or cats. 
Our research on energy demand and household cooling highlights a recent trend towards air-conditioning rooms or homes for pets. As well as cooling homes occupied by both humans and their furry friends, air conditioners may be left on when dogs or cats are home alone. 
Some pet owners also leave doors and windows open for their dogs and cats to move between indoor and outdoor areas. This means that air conditioners have to work harder and use more energy to maintain indoor temperatures.
Our research is consistent with an emerging international trend towards the “humanisation of pets”, which is contributing to energy use in households. 
A 2013 study released by E.ON UK (a UK power company) on “hot-dogs and thermo-cats” found that more than half (52%) of UK pet owners turn up the heating for their pets when they go out. Some UK households also leave radios or televisions on for pets so that they don’t get lonely when their owners leave the home.
In other areas of everyday life, cats and dogs now play iPad games, eat specialised diets, have heated mats or air-conditioned kennels, and have their own fashion accessories and electronic toys.
The energy impacts of home cooling
On average across Australia, heating and cooling make up 40 percent of our energy use in households, not including hot water. 
Most Australians who live in southern states use cooling in their homes sporadically, turning it on during hot summer afternoons and evenings when they get home from work or other activities. The rapid growth in residential air conditioning for this purpose has been one of the main contributors to Australia’s peak electricity demand, which has increased energy bills.
Trends in pet cooling could change the energy demand for cooling in homes. Australia has one of the highest rates of pet ownership in the world, with 63% of households keeping an animal as a pet. 
According to a 2013 report by the Animal Health Alliance, there are 4.2 million pet dogs and 3.3 million pet cats in Australia. Of these, 76% of dogs and 92% of cats are kept exclusively or partly indoors. 
Providing air conditioning for pets during the day when people aren’t at home would raise residential energy demand. It could also extend and possibly increase electricity peaks if more areas of the property (such as kennels or garages) are being cooled for a longer time.
What makes pets hot?
Although cats and dogs differ in their physiology, in general older, sick or overweight pets may be less resilient to the heat. Some breeds may also be more vulnerable than others. 
For example, short-snout dog breeds (Bulldogs, Pekes and Pugs) are more likely to suffer from heatstroke. This also applies to short-faced cats like Persians or exotics. 
Many things can exacerbate heat stress for pets. For example, people living in apartments may find it more difficult to provide cool outdoor spaces for dogs, or to engage in “waterplay”, as recommended by Pets Australia.
How to keep pets cool
Advice on how to keep pets cool varies and is different for cats and dogs. Pets Australia recommends providing cool spaces such as shade, cold tiles or digging holes in the soil. Other examples include giving dogs cool treats like frozen meat, providing lots of water for hydration and stopping exercise. 
Some websites recommend keeping pets inside on hot days, preferably with an air conditioner or fan turned on. Other sites recommend cooling mats or vests such as gel pads, which can be refrigerated or frozen prior to use. 
Murdoch University provides advice on how to recognise heatstroke warning signs, and what to do if you suspect your pet is suffering from heatstroke. The growing market for pet cameras is one way to keep an eye on pets while owners are out of the house. 
What needs to be done?
As climate change continues to increase the severity and duration of heat waves, the incidence of heatstroke in pets is likely to increase too. This applies especially to those living in energy-inefficient housing or with access to poor-quality outdoor environments. 
There is a clear need to seriously consider pet cooling in the design of energy-efficient housing and in energy policy that targets households.
It may also be timely to reconsider pet types and breeds appropriate for the Australian climate. Siberian huskies, for example, prefer cooler climates and may be more likely to suffer from heatstroke than breeds with smooth or short coats.
More research is also needed to understand how Australian households are changing the ways they keep their pets cool, and what can be done to reduce heat stress in pets without increasing energy demand or electricity peaks in homes.
In the meantime there is a range of advice on how to keep pets cool. Many creative solutions are available that don’t require leaving the air conditioner running.

Hot dogs and cool cats: keeping pets cool without blowing your energy bill

<html><body>
GUEST OBSERVER
Governments and private companies could save millions of dollars and drastically reduce their carbon footprint with a simple adjustment to the way they use air conditioning.
Air conditioning systems were generally fixed at what is considered to be an optimal 22 degrees based on an arbitrary standard which took no account of outside temperatures and employee comfort levels. It turns out that we heat and cool the built environment to a fixed 22 degrees. Why? Because it is the thermal comfort level of a forty four year old man which was determined by the Americans in the 1950s. I kid you not. This is an arbitrary point that makes little sense and which costs governments and industry millions of dollars a year to say nothing of the impact on the environment. In 2008 the United Nations, as a publicity stunt at its New York headquarters, adopted a temperature range of 19-25 degrees. A month later the UN estimated the savings at one hundred thousand US dollars. In Australia some 40 percent of our energy is consumed in the built environment and a large amount of that energy is used in heating and cooling. The question is why wouldn’t you adopt some flexibility with regard to your air-con temperature settings? If we did this in Australia in office buildings and shopping centres, it would save a hundred million dollars and three hundred thousand tonnes of carbon emissions per year and it would not cost a cent. Now let’s run that out through all the other property in the country including residential and then run that out around the world and we are talking billions of dollars and millions of tonnes every year. Irrespective of the dollar savings, it was incumbent upon governments and industry to make that adjustment as part of their social responsibility.

Air conditioning at 19 to 25 degrees would save millions of dollars: Tony Crabb

<html><body>
Governments and private companies could save millions of dollars and drastically reduce their carbon footprint with a simple adjustment to the way they use air-conditioning, according to new research by Savills. 
In a presentation posted to the online knowledge clearinghouse TED (Technology, Entertainment and Design), Savills Australia’s national head of Research, Tony Crabb, said air conditioning systems were generally fixed at what is considered to be an optimal 22 degrees based on an arbitrary standard which took no account of outside temperatures and employee comfort levels.
"It turns out that we heat and cool the built environment to a fixed 22 degrees. Why? Because it is the thermal comfort level of a 44-year-old-man which was determined by the Americans in the 1950s. I kid you not," he said.
"This is an arbitrary point that makes little sense and which costs governments and industry millions of dollars a year to say nothing of the impact on the environment.’’
By way of an example, Crabb said that in 2008 the United Nations, as a publicity stunt at its New York headquarters, adopted a temperature range of 19-25 degrees. A month later the UN estimated the savings at US$100,000.
"In Australia, some 40 per cent of our energy is consumed in the built environment and a large amount of that energy is used in heating and cooling. The question is why wouldn’t you adopt some flexibility with regard to your air-con temperature settings?
"If we did this in Australia in office buildings and shopping centres it would save a hundred million dollars and three hundred thousand tonnes of carbon emissions a year and it would not cost a cent. 
"Now let’s run that out through all the other property in the country including residential and then run that out around the world and we are talking billions of dollars and millions of tonnes every year,’’ Crabb said. 
Irrespective of the dollar savings, he said governments and industry should make the effort to adjust the air-conditioning as part of their social responsibility.
