The Lower Broadford Guest House is sited on a 7-acre property in rural Bellevue, Idaho. Located 18 miles from world famous Sun Valley Ski Resort, this project was designed to withstand the snow and cold climate conditions of mountainous Idaho. The dwelling unit and garage building was the first of two phases, where the second phase will be a main residence. The exterior materials were inspired by the local barn vernacular while designed and detailed in a contemporary fashion. A rusted patina was applied to cold rolled sheet metal panels, creating hues of brown, red, gold and green. The rich tones of the rusted metal panels are contrasted by silver colored reveals of Galvalume Plus cold rolled hat channels. A rusted steel superstructure was constructed to perform several functions: vertical circulation to the dwelling unit, elevated outdoor living, and a off-axis visual link to the future main residence. Rough sawn western red cedar board and batten siding was stained dark brown to blend in with the rusted metal panels. Two evacuated-tube solar collecting panels provide heat to the domestic hot water and augment the hydronic radiant floor heat system in the dwelling unit and garage. Passive solar heating is utilized in the dwelling unit through southern glazing and collected in ceramic tile flooring. The lower level contains 2 oversized garage spaces and 1 workshop bay, while the upper level consists of a 1 bedroom, 1 bathroom dwelling unit. Zoning ordinances limited the dwelling unit to 1,200 square feet, resulting in a building footprint of 28 feet wide by 42 feet long.
