The project

Project brief & construction scope.

This Castle Hill home was renovated and extended on a steep, sloping block. Construction photographs show the two-storey structure fully scaffolded and rebuilt from the front elevation back, with a Panadium site sign and liveried ute on site confirming the build. At the rear of the block, a new indoor pool and spa room was built, with a curved wall of glazing opening the room to the garden and a servery bar along one side. A rooftop terrace sits above, reached by an external stair tower with curved glazing, and looks out over the treetops to a distant view of the city skyline. Inside, the finished home includes a living space with a tall glass-block feature wall beside the stairs, a main bedroom with sliding doors to a balcony and an open walk-in wardrobe, and more than one upgraded bathroom — one with a freestanding bath and full-height tiling, another finished with a floor-mounted toilet and a pedestal-style basin. The result is a renovated and extended home that resolves a difficult, sloping site with connected indoor and outdoor living across its levels.
