Project: Streeter House Location: Deep Haven, Minn. Architect: David Salmela, Architect Owner: Kevin Streeter The client, a contractor of high-end custom homes for the last 20 years, built this house for himself, setting a simple goal of using prefabricated systems and materials and set a standard for sustainable construction methods. With a small parcel of land that many had deemed unbuildable because of an easterly pond and a westerly wetland, the architect developed a design generous in its functions, sensitive in its relationship with the land, and honest in its expression of materials. The house comprises a simple kit of parts: glass, concrete block, Glulam beams, structural insulated panels (SIPs), and pipe. The architects worked with a local manufacturer to make the 12-inch x 12-inch by 24-inch black fly-ash concrete block specifically for this project. The intent was to leave them exposed on the exterior and interior, eliminating the need for standard wall finishes. Similarly, the poured and polished concrete floor is left exposed on the main level and all galvanized and plastic pipes for the electrical and mechanical conduit are left raw and exposed like veins throughout the house.
