Name: Cosgriff House
Designer: Christopher Polly
Location: Sydney, Australia
Cosgriff House is a minimalist house located in Sydney, Australia, designed by Christopher Polly. A substantial lower ground room is inserted under the original fabric, harnessing the fall in the site towards the rear. It extends deeply beneath the existing dwelling and outwards towards the garden to transform the original dwelling in combination with the re-crafted rear of the ground floor above.
The project retains its original envelope and significant portion of its ground floor fabric as part of its overriding environmental and economic sustainability objectives. New work is substantially embedded within the existing footprint, with only a modestly-sized 20sqm addition to the rear. Vaulted ceilings and skylights carved within the original roof form expand volumes for access to light and sky within the middle of the ground floor – while a stair hall, cantilevered balcony and generous void spatially expands to the lower level below, and upwards to views of the external environment to strengthen connections to its setting.
