The Flinders House was designed as a holiday house for an extended family to occupy over short periods of time. Part of the brief required the house to accommodate a large group of people (up to twenty) as any one time. with a tight budget, its size had to be contained to keep costs down. It was rationalised that the house could be separated into two separate volumes, a two-storey square box dedicated to sleeping, and a "living", single storey rectangular box connected by slender link.
