Cushing Terrell has designed Confluence House, conceived as a getaway for family and friends. Situated on a 10-acre (4-hectare) plot at the meeting of two rivers near Whitefish, Montana, USA, the residence is composed of three structures in a loose triangular form — 2,282-square-foot (212-sqm) main house, 946-square-foot (88-sqm) guest house, and utility structure.
The flat-roofed living structures allow the complex to disappear into the horizon line. The main house, aligned with the west bluff, holds all the usual living spaces plus a study, piano room, large mudroom and pantry, and well-appointed master suite. A model of efficient space planning, there are no hallways. The guest house is separated from the main house to provide privacy. Connected via a covered porch, and aligned with the east bluff, the guest house contains two suites that can be combined to create a family-style suite, as well as a second study/exercise room. The covered porch between the house and guest house features a wall-mounted TV for outdoor movies. The utility structure, reminiscent of old railway maintenance sheds in the region, serves to screen the house and courtyard from the access road. It’s topped with an expansive solar PV system. The breezeway between the garage and shop ceremonially brings guests into the courtyard which is planted with native, drought-tolerant vegetation, mirroring the landscape around it. A stream bed flows through the courtyard, collecting rainwater that pours onto it from scuppers on the roof. Strategically sited boulders, and plantings of grasses and such perennials as Alberta penstemon and wild bergamot, meld with the surrounding ecosystem.
Exterior building materials are tough to match the local climate and feature dark-stained locally-sourced wood and stone, and a metal roof. Large, floor-to-ceiling, energy-efficient windows provide dramatic views to mountains, rivers and the valley. Inside, polished, exposed-aggregate concrete floors subtly recall the gravel beds of the nearby rivers while whitewashed Douglas fir ceilings suggest the soft, natural tones of weathered wood. Furnishings are comfortable yet durable and contribute to the carefree environment.
