The brief for this project was to completely reimagine an existing single-story bungalow by raising the roof and adding an entirely new floor. The new highly insulated upper level houses two en-suite bedrooms, including a generous master suite with a walk-in wardrobe.

Externally, the geometry of the new roof is expressed through two striking pitched gables, clad entirely in a rainscreen of Douglas Fir. The natural warmth and vertical grain of the timber sits above a dark, monolithic base.

The architectural language is driven by an adherence to elemental materials: timber, marble, and steel.

At the center of the plan, a double-height void connects the two floors. Within this bright, white space sits the core architectural intervention of the house: a sculptural, brilliant red helical stair.

The stair is an exercise in structural purity. It has no central supporting post; its structural integrity relies entirely on the outer 8mm steel balustrade plate, which was rolled into a continuous sweeping curve from a single sheet of steel.

Upstairs, the roof form creates dynamic internal volumes. The entire underside of the new pitched roof is clad in large, single sheets of high-quality birch-faced ply. The warmth of the ply acts as a continuous canopy over the upper floor.

To keep the ceiling planes entirely clean, lighting is handled via precise, linear LED strips set perfectly flush into the face of the birch ply, emphasizing the sharp angles of the roof geometry.

The same elemental approach is applied to the new bathrooms, which are clad entirely in real Italian marble, providing a heavy, luxurious contrast to the lightness of the ply and the glass. The house is fitted with an MVHR system for continual air exchange and underfloor heating throughout, hidden behind the precise material finishes.
