California studio TW Ryan Architecture has completed a wildfire-resistant house in the American West that features a Corten steel exterior and pyramidal roofs that allude to the mountainous terrain.

Located in a remote part of central Montana, the Four Roof House was designed for a couple who wanted a low-maintenance home where they could age in place.

Their chosen site was a bluff overlooking a lake near the town of Helmville. The site came with challenges, such as fluctuating weather conditions and threats of wildfire.

"The micro-climate of the area is known for its harsh variability, including 30-degree temperature swings, wildfires and high snowfall, relived by summer months of wildflowers and abundant wildlife," said TW Ryan Architecture, which is based in northern California.

A key goal for the design team was to create a rugged home that could "withstand the ever-changing weather conditions, while reinforcing a refined engagement with the natural landscape of the unique site".

The team conceived a 5,000-square-foot (465-square-metre) dwelling that is sited in a way that prioritises solar orientation and views. One side of the home is set at an angle, adding a dynamic quality to the plan.
