Baker House is the first major building to synthesize European Modernism with the regional material vernacular of New England. It is also a pivotal building in architect Alvar Aalto's career and the most significant of his works in North America. The building is an undulating slab clad in the rough brick of the region’s Georgian vernacular. A series of spaces, axially turned back toward the campus, bisect the slab near its midpoint. The termination of this axis is a dining pavilion, clad in limestone with wood framed ribbon windows and Aalto's signature bank of circular skylights. On the north facade hangs a great stucco-clad stair whose rough, Constructivist aesthetic is a direct response to the industrial East Cambridge neighborhood in which the building was originally set.
