“Architecture is the medium between the artificial and natural worlds. Building Physics makes this medium the best it can be by working with both the artificial and the natural worlds.”
Expert thermal performance consulting across Australia. From Passivhaus to NatHERS — we make buildings comfortable, efficient, and compliant.
We don't start with compliance checklists. We start with what matters to you — then use building science to balance your design.

Alex Slater is an architect who found his inner nerd and turned it into a superpower. After years of designing buildings, he had an existential crisis and realised he cared more about how they performthan how they photograph (he didn't realise a building knew how to use a lens cap for many years).
Certified Passivhaus Designer, Accredited NatHERS assessor, and firm believer that thermal comfort is a no-brainer available to all — not a luxury reserved for people who enjoy reading insulation datasheets (though he does enjoy that too).
Alex also leads Shared Space Architecture, where design and building physics go hand in hand — like a well-detailed window frame.

Podcasts, talks & presentations
In this episode of Passive House Podcast, co-host Matthew Cutler-Welsh reconnects with Alex Slater from Shared Spaces to delve into the latest advancements and challenges in sustainable design. Alex shares his recent work on the Passive House Planning Package (PHPP) and its application in compliance with Australian building regulations. They discuss the significance of energy efficiency, the impact of thermal mass in various climates, and the importance of education and humility in promoting sustainable practices. Alex also reflects on the recent Thrive24 conference, emphasizing the need for a collaborative approach to advancing Passive House standards in Australia.
When a Mad Scientist becomes really excited about what they want to tell their clients, this is the kind of pattern which can happen… first we say something and show a graph… then we say something else and show another graph… and we keep going until the client has no idea what’s going on… and then a bit more. This prompted me to start working on something for my reports. It is called RePHorter. Imagine a report where I can copy and paste decent graphs into an A4 format in word and not have to recreate these again and again! This was the thought going through my mind which eventually took hundreds of hours to create graphs which are easy to read to the least sophisticated creative nerds… our clients, mainly the visual type.
“Alex is the Dr Carl Sagan of Building Science or The Science of Better Building. He makes it easy for people to understand.”
“We've enjoyed working with Alex in his role as a Sustainability Consultant - providing Passivhaus services for a number of our early projects that were aiming for the Certified Passivhaus Standard. His knowledge about Building Physics extends beyond the theoretical, to a comprehensive practical understanding of how these homes are constructed. We love that he's a spreadsheet nerd - which meant we could collaborate and focus on our strengths to deliver outcomes for our clients that met their expectations (and sometimes exceeded them too!).”

For each project, we generally suggest a free initial 30-minute consultation where together the scope and compliance requirements of the project can be worked through and clarified.
Our mailing list is irregular and typically insightful. We aim to demonstrate ideas, challenge the status quo and be a friendly voice with a message.
