Barwell House

The brief for this adaptable family home in Curtin focused on functional spaces, a communal living hub with connection to the backyard, and a simple exterior to compliment its leafy surrounds.

Simple, stylish and liveable

The clients came to us looking for a simple, functional and adaptable family home, with a separated parents’ area and the ability to accommodate long term guests. Their vision was for a simple and restrained exterior that complemented the home’s setting amongst many large leafy trees on a quiet cul-de-sac in Curtin.

The main living hub of the home opens up to a sunny backyard deck. A separate lounge to the front of the house allows for a second living space to be zoned off with large sliding doors for multi-purpose use. An open timber stair leads to the north facing parents’ zone – a study at the top of the stairs, ensuite and master bedroom with a roof terrace facing the street.

Simple white forms shape the exterior to catch the silhouettes of surrounding trees. The external material palette is softened with areas of cedar cladding and detailed steelwork. Outdoor areas are thoughtfully arranged around and between the building forms resulting in a sun-filled interior with outlook to private gardens from every room.
