Collins and Turner’s three storey residence in Point Piper has recently been topped out with a slender steel roof frame engineered by Partridge Partners. When complete, this gently vaulted roof will be internally finished with a seamless woven copper lattice ceiling, creating a space that will frame sweeping views of the harbour from Blackburn Cove to the south through to the Sydney CBD skyline. At completion, the building will be characterised by a palette of warm natural materials including Wandabyne sandstone, reclaimed Western Australian Karri, copper, brass and European limestone.
