4-FRAME
A two-storey mass-timber addition to a West Perth workers’ cottage.

On a 5 m-wide site, the structure lifts and folds to pull morning light deep into the plan while tempering the western sun.
A 64° raked roof resolves light, volume, and envelope in one move.

Planning approved.
Construction commencing Q2 2026.

WATKINS — White Gum Valley

House with ancillary on residual infill land. A sloping corner block. Two street frontages. A tight, leftover subdivision lot — great challenge!

✅ Planning Approved

The Fremantle Council minutes described the home as “a desirable well thought through proposal on an extremely challenging site.” The support letter notes that it “enhances rather than disrupts the local streetscape and residential amenity.”

A compact home shaped by constraint, with the loft folded into the roof form and a permeable timber screen softening the western sun.

PATTERNS* — early development studies for a new series of pre-designed homes.

These scale models are part of an ongoing exploration into compact, efficient and highly calibrated houses using CLT construction — chosen for its speed on site, aesthetic warmth, structural clarity, environmental performance and raw material beauty.

The ambition is simple: well-designed homes that are faster to build, lighter on the planet, and richer to live in. A quiet response to urban infill, construction cost uncertainty, and the need for more considered housing options. Conventional building methods will also be supported.

We’re still shaping the series, so we’d love to know what people are looking for in a home — size, make-up, flexibility, materials, cost, lifestyle, landscape, anything and everything.

Comment below. More soon.

DOLMEN — Yanchep

A new coastal addition for a retiring couple, designed around a simple question: how can a house become more useful, more protected, and more generous with age?

The project retained the existing 1980s project home as a place for family to stay, while the new addition created an age-in-place retreat that could support changing care needs over time, including live-in assistance or palliative care if ever required.

Set into the exposed coastal edge of Yanchep, the house was imagined as a quiet fortress against sun, wind and salt. Robust sand-cast concrete walls were explored as a way of embedding the building into its place, using local sand textures and scale-model testing to study different wall finishes, from smooth cast surfaces to rough, eroded faces.

Operable shading protected the western edge while preserving long ocean views. The plan folded into a U-shaped courtyard around an existing coastal tea tree, allowing the tree to complete the outdoor room and create a protected deck at the centre of the house.

The project ultimately did not proceed in Yanchep, with the clients selling the site. The conversation has since moved to Swanbourne, where we are now exploring the refurbishment and addition of a charming old cottage.

PROGRESS — construction steaming along at Roux House with @bruceconstructiondesign

With the roofs now on, just in time for the rains, the spaces begin to take on their intended volumes and the first feeling of the home’s spaces begin to set in.

This is a home of compression and release, making the most of the narrow block, the surrounding treescape and the onsite peppermint tree. The intimacy comes with the tension between low vs high, close vs far and dark vs light.
