Clay House transforms a narrow, south-facing terrace in Woollahra into a family home and built manifesto for ceramic building materials company, LOHAS. The project explores the versatility of clay across floors, walls and ceilings, as well as domestic elements including lighting and basins.
The extension is organised as two solid ‘towers’ separated by a central lightwell that draws northern light deep into the plan, creating a sequence of connected rooms rather than a single open space. This approach introduces spatial variety and depth that is unusual within such a compact footprint.
A terracotta bovedilla system forms the permanent formwork to the concrete floors and roof, reducing material waste and creating a sculptural, textured ceiling. Brick screens filter light and views at the upper level, while generous openings at ground level strengthen the connection to garden and extend the perceived width of the terrace.
The home feels like a true sanctuary where my family can properly relax.
It isn't just about how easily the outdoors flows inside, it’s also the way it wraps around us like a warm blanket. It feels protective and cozy. The perfect place to retreat to. Â
Even during heavy winter rains, the house holds a warm, cozy atmosphere that turns the elements into a peaceful backdrop rather than a challenge. The layout and materiality do not just accommodate us, they make life better. They nurture and restore us by offering a sense of safety and belonging.
