The Space from the inside ✨

Window and door openings are still wrapped and protected from the weather, but even at this stage the space already feels like a cosy shelter from the outside.

With the HRV and electrical rough-in now in place, it’s exciting to see the layers coming together and the project starting to feel more like a home. It will be lovely once the windows are in and we can experience the spaces with natural light instead of improvised site lighting.

Love this stage of the build, when the spaces are already formed and you can finally start to feel how good it’s going to feel to be in them.

Glass brick install day at The Sunny ☀️

I’ve always loved glass bricks. There’s something nostalgic and timeless about them... I saw them a lot in Brazil, bringing soft light into homes while keeping privacy.

Beyond the aesthetics, they’re actually quite interesting thermally too. The sealed air cavity inside the blocks gives them better performance than standard glazing, while the textured glass diffuses sunlight and slows heat transfer compared to clear glazing, creating a gentler quality of light and warmth throughout the day.

For the building science nerds: some glass block systems can achieve Uw values around 3 W/m²K with SHGC (g-values) around 0.68 allowing useful winter solar gains when used intentionally for passive heat gain, while still bringing in plenty of daylight and diffusing glare. The blocks are also inherently airtight as individual sealed units, and when detailed correctly as an assembly they contribute to a well-sealed envelope, with most performance depending on the perimeter detailing and junctions.

Watching the install was fascinating as wel: slim framing brackets, EPS insulation wrapped around the opening, reinforced steel within the mortar joints… all the little details that help make these assemblies durable and perform well over time.

A very big day for a very small building.

Last week, The Space arrived on site as a prefabricated high-performance shell by .com.au and within hours, walls and roof panels were standing in the middle of a cold Blackheath day.

This little project is targeting Passivhaus certification and designed to be a space focused on comfort, health, low energy use and thoughtful small-scale living. Seeing months of drawings, coordination and problem-solving suddenly become a physical space was honestly a bit surreal.

The reel shows the step-by-step assembly process, crane lifts, first panels going up, and the structure slowly taking shape throughout the day.
Also featuring: my very glamorous flu voiceover and impressively blocked nose narration. Premium architectural commentary...

Prefabrication like this helps reduce weather exposure during framing, improve build quality and speed up construction on site... Which feels particularly valuable in the Blue Mountains climate.

Huge effort from everyone involved on the day. Watching it all come together was pretty special.

A big thank you to:

Window install day at The Sunny ☀️

This Extend & Enhance project in Blackheath has been warmly nicknamed “The Sunny” after the clients’ wish to create a space where they could soak up winter sun without feeling frozen during the cold and gloomy mountain days.

Today the high-performance double glazed windows and doors started going in and it’s incredibly exciting to see the project beginning to come to life.

Behind the scenes, a lot of care has gone into creating a healthy, comfortable and durable extension to this beautiful existing heritage home. The slab was insulated, walls with additional insulation, and appropriate membranes and internal airtightness layers will be carefully installed to improve thermal performance and longevity.

The builders were new to high-performance construction methods and have done such a great job learning the systems and applying the products with care throughout the build process.

I’ve also included a few renders showing the intended finished outcome... including the warm, light-filled bathroom featuring a beautiful glass brick opening and earthy tile palette selected by the clients.

A project grounded in warmth, light, comfort and thoughtful detailing.

The decisions we make today will shape what gets built tomorrow.

I’ll be speaking at as part of that conversation.

Innovation for a Better Built World is the theme, so it’ll be a valuable few days for anyone working in design, construction and development.

On the drawing board...

Feeling incredibly lucky to have lovely clients who place their trust in us.

This beautiful new home draws inspiration from Scandinavian design, grounded within the Australian bushland landscape. A modest footprint, natural materials, passive solar principles and high performance design come together to create a warm, calm and energy efficient mountain home.

Vertical natural timber cladding, black detailing and a strong connection to nature give this home a quiet simplicity that feels both modern and sophisticated.

We can’t wait to see how this design evolves and look forward to sharing the process with you.

Building in Blackheath means working with the weather, not against it.

Prefab panels help by getting the structure up quickly and reducing exposure to the elements.

It’s a smarter, more controlled way to build.

The catch?
You need to commit to the design early. Once fabrication starts, changes are limited.

Front-load the thinking, simplify the build.

For this project, we’re installing the bottom plate, a key set-out element fixed directly to the slab. It sets the alignment for the prefabricated system, so getting this stage right is crucial.

Wall and roof panels are being prefabricated off site and will arrive in a single delivery. They’ll be lifted straight into place by crane.

The panels are lightweight, pre-insulated, and come with internal and external membranes already applied. On site, it’s about fixing them together and carefully taping all joints to maintain the integrity of the envelope.

It’s a controlled, efficient process that supports build quality and performance, while reducing time on site. Less time exposed to the weather means a drier, more protected building envelope from the start.

Slab day always feels significant. There’s so much happening beneath the surface here, with every pipe and connection placed exactly where it needs to be before being covered. Now it’s all set in place and finally we can see some real life scale of The Space.
