Minimal Pettit & Sevitt bush house with natural materials

Architectural legacy

In the 1960s and 1970s, Pettit+Sevitt pioneered architect-designed project homes, and in doing so, created what could be considered the first truly Australian architectural homes.

Collaborating with renowned architects like Ken Woolley and Russell Jack, they tailored efficient, affordable, modern and functional designs to the local landscape and made them accessible and affordable to the masses.

Today, well-kept Pettit+Sevitt homes are collector’s items, and this one is no exception.

Project context

Perched on the edge of sprawling bushland, this updated 1967 Pettit+Sevitt MKII is a brilliant reinterpretation that respects the original Ken Woolley design while adapting to the needs of a contemporary family.

The challenge on this project lies in simultaneously honouring an iconic design whilst also meeting the stringent requirements of the BAL FZ (flame zone) bushfire zoning.

The result is a home that engages with its natural surroundings and stands as a more resilient and valuable collector’s item.

Design response

Step one in this project was the removal of a 1980’s addition to make way for the new, for more space and comfort for the family of five who live there.

The skillion roof, a defining feature of the original design, was replicated to preserve the home’s architectural identity.

Oregon beams, another signature element of the home, have been retained and stained black to bring a modern feel to the home’s historic roots.

Spatial experience

Openness, space and visual connections were priorities in the redesign for the family who call it home.

Reconfiguring the layout has enhanced the flow of the interiors and lines of sight (both within the home as well as to the views outside), creating an environment that feels expansive and also intimately connected.

Bushfire response

BAL-FZ materials, required for bushfire compliance, were made with careful considerations in order to meet regulatory requirements, harmonise with the natural environment and maintain a beautiful, aesthetically pleasing home.

Compliance is one thing, enhancing a home’s intrinsic value is another, and the update to this Pettit+Sevitt MKII has been a success in achieving both.
