Situated at the fold between the Rocky Mountain foothills and the Great Plains, the house mediates horizons and peaks, city and alpine meadows, inside and out. Conceived as a frame for viewing the landscape, Arch11 meticulously modeled the residence within the site to ensure that planes of glass capture ridgetop views while respecting the city’s height restrictions. Built with innovative renewable energy systems and materials crafted to last centuries, the house is a model of cutting-edge sustainable design and attains a LEED gold certification. Roof gardens allow the land to literally envelop the house, and expansive, retracting glass walls provide full views of the Flatirons to the west while blurring the line between indoor and outdoor rooms. Executed with uncompromising detail, surfaces meet with quiet precision, creating a serene background for the landscape and mountains beyond.
