A western extension to the house, designed by Wrigley in 1966, is an example of the late twentieth century Sydney regional style , with its roof following the slope of the land and stained timber. Planning Section in 1957, remaining there for twenty years. The house is set below the level of the street to the rear of the block and is constructed of painted cavity brickwork, stud framing clad with timber panelling and fibre cement sheeting, concrete slab floors and galvanised steel roofing on timber framing. The original Melbourne regional style residence was a square shape, with the living areas across the north, bedrooms to the east and south and the kitchen and bathroom to the west and south. With the Sydney regional style extension to the west and a further, later extension to the east, the house is now a split-level 'L' shape.
Entry is to the north through a large courtyard under a pergola.
The centrally located front door opens directly into the living room on axis with the fireplace, a significant design feature of the house. It was designed by Wrigley, with an angled back of pre-cast concrete and is open to the sides with voids extending up behind the brick openings to below ceiling level. The enclosing brickwork has square openings below ceiling level to allow warm air to circulate. Down a wide, five step staircase is the family room, kitchen and dining room. These rooms comprised the first extension and all overlook the west rear garden through full height and width glazing.
