Why Castle Hill
Granny Flats built for Castle Hill blocks.
Castle Hill is overwhelmingly a knockdown-rebuild market — established blocks with strong land value where families want to stay in the catchment but rebuild for modern living. Wider frontages support generous single-storey and confident two-storey designs with premium street presence.
