Save our Sirius – #SOS

Save-our-Sirius-banner

Every bus ride across The Bridge – the tail-end of my journey from Sydney’s outer-west to its CBD – involves my eye being caught by one siriusly cool building. What is it about this concrete structure, that gets me every time? Maybe it’s the fact that this form is simply a series of stacked rectangular prisms… Or that its curated planter boxes give it life and human scale. Or perhaps it’s the simplicity with which it presents itself, and the way in which it seemingly defies the architectural language of everything else on the harbour – entirely honest; and categorically, ‘brutal’.

Surely there is something special about a building that, despite being amidst monuments like the Opera House, commands one’s attention.

Until the recent threat to this building’s existence, little did I know, that this was not just a Brutalist statement, but also a social one. Actually, I didn’t even know what ‘Brutalism’ was, when I first set my eyes on Sirius, having just embarked on my journey as a student of Architecture. But I didn’t need to know – Brutalism’s truthful expression of materials and structure speaks to one and all.

And three years later, as I sit in a room full of architects and heritage enthusiasts, being addressed by Glenn Harper of PTW, on the features of Brutalism, I learn that as one of the few remaining Australian structures of its kind, Sirius needs to be kept – not only as a testament to the country’s mid-century modernist boom and thriving concrete craftsmanship of the time, but also as a testament to the country’s belief that social housing does, in fact, have a place on Sydney’s sought-after harbour-front.

The protagonist of my story, whose name you are now familiar with – Sirius – was designed in the late 1970s for the Housing Commission, by architect, Tao Gofers. Now, three decades on, the housing estate is under threat by the government, who has rejected the NSW Heritage Council’s plea to list Sirius on the state’s heritage register.  Without a heritage listing, and with the building left purposely unmaintained, it awaits an almost-inevitable fate of destruction in favour of new private-housing development.

Already seeing Sydney’s suburbs being populated with apartment blocks at an incredible rate, I wonder whether we really need a few more on the harbour, at the cost of a cultural icon that speaks of the response of an architectural movement to a social cause: housing working-class residents who would otherwise not have been able to remain in the area at the time.

Perhaps, if it weren’t for Sirius’ noble function – if Sirius was nothing but a showpiece – I wouldn’t be sympathising with its supporters. But because it stands tall for the rights of those who aren’t as privileged as others – and gives them a prime spot on Sydney’s landscape – I am compelled to admit that I am one of its supporters.

If this piece of heritage and history defies today’s money-driven development of the city I call home – if it rejects the agenda of the ridiculously rapid erection of luxury apartments that lack architectural integrity and sustainability – and if it prioritises people over revenue, then how can I not hope for its continued existence?

And as I sit here, pen in hand, in a room full of architects and heritage enthusiasts, being addressed by Glenn Harper of PTW, on the features of Brutalism, I can’t help but question how and why the architectural brilliance of the Brutalist movement – its sensitivity to scale; its simple, modular approach to form; its bold brickwork and characteristic concrete; its unapologetic expression of mechanical services; it’s strong structure and modest fenestration – has been lost to an era of tall glass boxes that have questionable narrative or connection to place, in an economic race to be the tallest, fastest and fanciest. For in a bid to be iconic, are we forsaking the icons we already hold – and frankly – cannot compete with?

I believe a city’s character lives in its history and public buildings. If we are destroying these treasures, then perhaps it is time to revaluate our priorities as a nation. Siriusly.

Architectural Window Systems (AWS) is proud to sponsor the Murcutt Building Tours, a centrepiece of the inaugural Glenn Murcutt Architecture Foundation Symposium, to be held in Sydney from 11 – 13 September 2025.

Thank you for reading this post, don't forget to subscribe!

The Symposium, presented by the Murcutt Foundation, celebrates more than five decades of architectural practice by Glenn Murcutt AO, Australia’s most celebrated living architect. The program offers three days of tours, talks and events for architects, students and design professionals, culminating in a rare opportunity to engage directly with some of Murcutt’s most acclaimed works.

As part of its ongoing support for architectural excellence and sustainable, place-based design, AWS is sponsoring the Murcutt Building Tours on Thursday, 11 September, providing a rare, guided experience led by Murcutt himself through two iconic residential projects:

  • Nicholas House
  • Simpson Lee House

“I am so pleased that so many have taken the chance to see these two projects that were designed in such close collaboration with the clients at the time, and which have been so well loved and cared for over the many decades since. It is such a joy to share this work,” Glenn Murcutt AO.

“Glenn Murcutt’s works embody a profound sensitivity to landscape, climate and material — and they are best understood by being experienced firsthand,” said Angela Bevitt-Parr, National Marketing Manager at AWS. “AWS is proud to support this extraordinary opportunity for architects to deepen their understanding of Murcutt’s work and philosophy through direct engagement with these exceptional places.”

Beyond the tours, the Symposium will feature keynote addresses from Glenn Murcutt AO and Francis Kéré (fellow Pritzker Prize Laureate), the inaugural awarding of the Murcutt Pin, and a full day of talks exploring the themes that have informed Murcutt’s unique model of practice.

“Francis Kéré is one of the great humans, and a gifted architect who really shows architecture can make a difference in people’s lives. I have a huge amount of respect and time and a wonderful friendship with this man because of his integrity. I am so pleased that Sydney will get to meet him this year,” Glenn Murcutt AO.

In late 1994, two dedicated fenestration professionals, Gavan Pead and David McCleary, took a pivotal tour of Architectural Profiles Ltd (APL) in Cambridge, New Zealand. Inspired by APL’s customer-focused business model, they envisioned bringing a similar approach to challenge the Australian market’s basic, outdated aluminium windows and doors that dominated at that time.

Thank you for reading this post, don't forget to subscribe!

This vision led to the founding of Architectural Window Systems (AWS) in January 1995, with Pead as the first General Manager and McCleary as Head of Design. AWS launched with the release of the 502 sliding window and 541 sliding door – affordable, single-glazed products that immediately stirred the market. “In those days, profiles were hand-drawn, and every detail required precise verification,” McCleary recalls. Their commitment to quality was matched by strong supplier support, relationships that remain solid today.

To bring this customer-centric model to life, AWS built a robust network of independent fabricators across Australia, now exceeding 200, with unparalleled reach and service capabilities. Steve Butcher of Great Lakes Glass, an early adopter, recalls that “their passion was infectious, and if they were starting something new, I wanted to be part of it.”

AWS quickly became a trusted name in high-performance aluminium windows, with products designed to meet the needs of architects, designers, builders, and homeowners. With the launch of ThermalHEART™ in 2007, followed by ThermalHEART™ commercial in 2012, AWS introduced its first thermally broken products, raising the bar for energy efficiency. In 2003, David’s son, Mark McCleary, joined AWS, continuing the family’s involvement in the company. In 2021, Mark took over the leadership of research and design, guiding the development of innovative window and door solutions. That same year, AWS introduced ComfortEDGE™, a significant step forward in thermal efficiency. With additional ComfortEDGE™ products set for release in 2025, AWS continues to strengthen its commitment to energy-efficient solutions for the Australian market.

Reflecting on the success of the last 30 years, AWS General Manager Greg Taylor notes that “it’s our model that differentiates us. A supplier that is not only an extrusion supplier, but a reliable, supportive, engaged business partner that understands the need for continuous improvement”.

In 2025, AWS will continue to focus on improvement, introducing a class-leading digital environment for specifiers, fabricators, and staff, along with an automated workflow connectivity solution exclusively for AWS fabricators.

From roof colour to insulation, from appliances to landscaping, all the material selections made in a project form a part of the build’s overall sustainability.

Architects and Building Designers are tasked with the most important objectives; managing client expectations, design intent, – and of course budget all within site parameters and building compliance.

When it comes to achieving or exceeding a 7-star energy rating as part of the National Construction Code, few of these choices offer as much scope for variation and flexibility as the selection and application of window and door systems as a major component of the thermal envelope of the building.

Well specified windows and doors can be the difference between a thermally efficient design which comes in on budget versus an over engineered, high performing build that can confuse the most experienced specifier and possibly exceed budget – perhaps unnecessarily.

Thermally broken windows have long held the title of one of the most energy efficient solutions by offering the broadest application for use. By insulating the pathway for thermal transmission through the window frame, it’s a clever way to make the most from the durability of aluminium while reducing its conductivity – but extra components inevitably mean more assembly and a comparatively higher price tag.

So, is there a cost-efficient way to maximise energy gains, while maintaining strength and design flexibility without turning to thermally broken windows?

That’s a question both asked and answered by leading supplier of aluminium windows and doors, AWS (Architectural Window Systems). This fundamental question was asked over 10 years ago and it led to the development of a more cost effective, energy efficient solution which also offers a contemporary design aesthetic in the current market.

Cue ComfortEDGE™

ComfortEDGE is an elegant, double-glazed solution for residential applications that rivals the energy efficiency of thermally broken products. Its embedded frames provide a sleek design comprising fewer components than thermally broken counterparts, making it a cost-effective, wholly Australian made option for Australian projects. ComfortEDGE recognises that clever design doesn’t have to be complicated, and skilfully minimises the amount of exposed frame by embedding into the timber reveal, insulating against the environment to improve energy efficiency and thermal comfort.

ComfortEDGE truly is the perfect meeting point of form and functionality. It’s stylish and high performing, with U Values as low as 1.9 – placing you in the best position to meet 7-star energy provisions while keeping your budgeton track.

Back to weighing up your options… How will you know if ComfortEDGE is right for your project?

AWS recommends consulting your specification expert early in the design process, taking a holistic approach to build sustainably and to meet energy compliance on budget. For designers looking to harness the vast possibilities afforded by Australian designed and manufactured architectural windows, give your AWS specifier team member a call and reap the rewards.
