Obsidian House
A private residence in dark board-formed concrete, detailed to weather without patina.


Five sectors. One office. The same people from survey to handover.
We organise by sector because that is how the constraints differ — a housing envelope, a bridge deck and a depot yard are three different problems wearing the same word.
What does not change is who does the work. There is no hand-off to a delivery team, because the people who drew it are the people on site.





Private houses and multi-unit housing, from elevation to envelope.

Offices and retail where the elevation carries the tenancy.

Bridges, crossings and grade separation on live networks.

Schools, civic and healthcare buildings built to outlast a budget cycle.

Warehousing, depots and plant where structure is the architecture.

A cast-concrete office elevation stepped to hold afternoon shade across its west face.

A pedestrian river crossing — post-tensioned deck, single pier, forty-metre clear span.

An eight-metre cantilever carrying a shaded terrace over the approach court.

A distribution depot with hardstanding sized for full articulated turning circles.
