The American Institute of Architects has announced the recipients of its annual awards for excellence in housing design. The eight AIA winners in the one- or two-family housing category included the Streeter House in Deep Haven, Minn., by Duluth-based Salmela Architect. The house is constructed of simple elements such as Glulam beams, glass and structural insulated panels, better known as SIPs. Black fly-ash concrete block and pipe were left exposed inside, eliminating the need for wall finishes.
