The house is one of a pair of heritage-listed semis, built in 1972 on a steep waterfront site looking across the Parramatta River towards Iron Cove to the south, and Birkenhead Point to the west.
Built at a 45 degree angle to the street, the semi zig-zags along the south boundary to side-step trees and sandstone outcrops. Its three-storey concrete pillar and slab construction was infilled with floor-to-ceiling fixed glass. The superstructure was solid, but its timber cladding and windows were beyond repair. Inside, much of the original interior had been covered up and painted, concealing its materials and character. With no opening windows to the south and west facades, and an uninsulated flat roof, the building suffered extreme heat gain in summer and loss in winter. It relied on a commercial-scale air-conditioning whose mechanical plant occupied half the lower ground level
The pair of semis were owned by the eminent Melbourne architect Sir Roy Grounds and his son Marr Grounds, an architect, university lecturer and sculptor.
It is believed that Marr commissioned Stuart Whitelaw to design and oversee the construction of the semis (no. 6 and no. 8). Marr had occupied semi no. 6 while Roy used no. 8 as his Sydney pied-a-terre.
