Located in the foothills of the Berkshires, Mount Mauwee House is tucked deep into the woods on one of the highest peaks in Connecticut. Its deceptively simple form uses prefabricated trusses and traditional building methods to create intriguing spaces with efficiency, while its material palette imbues it with warmth and texture. The challenge was to design a cost-effective house within a minimal footprint to preserve the surrounding landscape. The design process began by looking at traditional colonial-era homes in the region that are built of masonry, have large eaves, and have a second story built inside the roof. These simple structures are both beautiful and extremely efficient. The exterior appearance is that of a single-story home, yet upon entering the interior opens up to a series of light-filled lofted spaces over three stories. The uppermost floor, contained within an asymmetric hip roof, extends beyond the lower level to create an exterior room with framed views of the Catskill Mountains. To minimize cost and to expedite the construction schedule, the structure is made of prefabricated roof trusses supported by standard framing. The entire roof assembly is constructed of 63 unique trusses that structurally shape evocative spaces and openings on the upper floor. The cost savings and economy of means allowed for a more robust investment in custom detailing and materials. Mount Mauwee House achieves timelessness through its simplicity, innovative use of standard construction methods, rigorous attention to detail, and responsiveness to the site.
