Shadowbox is a Montana retreat that epitomises rest, reflection and recovery

Architect Cavin Costello, the creative mind behind Shadowbox, a weekend retreat for a private client in Montana, offers a captivating story when asked about the project's origins and what attracted him to it. His practice, The Ranch Mine, is based in Arizona but has been busy expanding with work outside their home state - with dedicated personnel in Bozeman, Montana, a short ride from Whitefish where this minimalist architecture project is located.

'The Ranch Mine was founded to create homes for modern pioneers, the trailblazers who know the path to a better future starts at home. The clients perfectly fit this description. They wanted to do something original, to create a one-of-a-kind retreat in the heart of Montana’s wilderness, a sanctuary where modern luxury met the natural splendour of the area,' said Costello. 

'Our origins are in the desert but we have been growing our team and experience to specialize in working in the mountains as well. Mountains are more than just a place to us, they often define a way of life.  This project was exciting as it gave us an opportunity to show our unique approach to residential architecture in a different climate, a wet pine forest in the Rocky Mountain area of Northwest Montana.'

The scheme is a holiday home - a getaway haven in the mountains, designed to allow its guests to connect with the environment and enjoy serene escapes in a subtly luxurious, design-led environment. The house includes four bedrooms and three bathrooms, including an expansive living space which opens up to dramatic views of the surrounding forest nature. 

Costello and his team spent time on the site, taking in the natural context before finalising their design. The result was 'inspired by the crisscrossing mountains that form the nearby glacial valleys of Glacier National Park. Shadow Box's silhouette captures the essence of these timeless marvels,' he explained. 

The structure's simple, geometric volume is clad in black standing seam metal siding, with different rib patterns alternating along the elevation. This echoes the differing ridges and furrows of the surrounding pine tree bark - while the dark colour creates a striking contrast to the green trees around it. A recess clad in hemlock marks the main entrance.

Costello also spoke of the project's challenges, as measures needed to be taken to ensure the space is safe against weather fluctuations and fire: 'Designing in the mountains also comes with challenges such as rapid and extreme fluctuations of weather and often living in areas where wildfires are common. The property is in the Wildfire-Urban Interface, or WUI, a term used for areas that experience wildfires.' 

'Specific attention was taken in the design to harden the structure and reduce the threat by creating defensible space around the house in the landscape, using a Class A metal roof assembly that is effective against severe fires, non-combustible metal siding, WUI-compliant decking, and significantly reducing exterior vents and other common fire prone building elements.'

Everywhere in the house, the outdoors becomes a key focal point as guests travel through the interior - either through large openings or other connections, such as the covered patio containing the sauna, fire pit, and sunken hot tub.

'The house is all about the unique experiences it creates while being there, it’s not about trying to pretend to be a cowboy or trying to take on the rustic identity of the old American west. Whether enjoying the framed view of the forest in the sauna or stargazing by the fire pit or in the hot tub beneath the Montana sky, every moment was designed as an opportunity to commune with nature,' said Costello.

'The great room ceiling soars to over 25 feet tall and has windows on all sides for ample natural light and to take in the majesty of the surrounding pine trees and landscape, creating a snow globe like effect in the winter. When designing homes in mountainous regions we focus on providing a place of refuge from the severe environment to recover, rest, reflect and re-energize before heading back out on the next adventure, and I think this house epitomizes those ideas.'
