Established in 1986 by Peter Haig AIA and John Ingwersen AIA; the firm's two award-winning principal architects hold degrees from Harvard and MIT and bring to each project over 30 years experience working with top Boston firms and clients on Cape Cod; the Islands and beyond.

The firm's portfolio includes over 500 projects ranging from new custom homes to major additions and renovations. As a testimony to the firm’s exceptionally personalized design process; the style of each home is as diverse as the backgrounds and personalities of each client.
