Six Moon Hill is a residential community dwelling that was designed by The Architects' Collaborative ( TAC ) and is located in Lexington, Massachusetts. The houses were designed and built in a modernistic way, in which traditional housing aesthetics were not used. The method of desgn was rectangular, flat-roofed, timber-sided homes, which was typical for residences designed by TAC. The houses are situated on a sloping hill lining a small road that forms a cul-de-sac.
