Confluence House

Project Details

Project Description

Situated on ten acres at the meeting of two rivers near Whitefish, Montana, Confluence House is a fly fisherman's dream. Conceived as a getaway for family and friends, the home’s design is derived and influenced by the geophysics of the surrounding landscape; becoming a seamless addition to the natural environment, rather than an interruption. Views from the toe of the bluff toward the river basin are lush and dynamic, while the distant mountains form a dramatic Montana backdrop.

Composed of three structures in a loose triangular form—main house, guest house, and utility structure—the two living volumes (2,282-square-foot main house and 946-square-foot guest house) are aligned with the two converging river bluffs. The utility structure (garage and wood shop) form the third leg of the triangle and screen the house from the access road. Together, the three legs form a protected central courtyard.

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.

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. Furnishings are comfortable yet durable and contribute to the carefree environment.
