W. Timothy Hess
Principal
Tim’s passion and capacity for designing authentic, contextual places and comprehensive, immersive environments has helped win national and regional awards for the homes, flagship retail, restaurants and neighborhoods he has designed. He earned his Bachelor of Architecture degree at Cornell University and practiced with leading design firms in New York City and Greenwich, Connecticut before moving to Massachusetts in 2004. He developed a thriving and award-winning design department in three years with a Groton Design/Build contractor, and integrates all of his broad experience in his role at DSA.
Tim founded and leads DSA|Moonlight Studio, a volunteer after-hours program whose motto is “we design like we give a damn”. The studio has designed entries for the SHIFTboston, Build-a-Better-‘Burb, New Bedford Whaling Museum, and Waltham’s Embassy Park competitions, placing 2nd in New Bedford. Other Moonlight projects include a deep-green 20-acre artists’ co-housing neighborhood and farm, and a light-green house for the North-Central MASS chapter of Habitat for Humanity.
Tim is an advocate for sustainability and community as a member of the International Living Building Institute and the Congress for the New Urbanism. He has served the Town of Groton on the Planning Board, Open Space and Recreation Committee, Station Avenue Design Guidelines Committee, and Cultural Council. Tim has taught in the Architecture+Design program at the University of Massachusetts Amherst, and is a frequent guest critic in undergraduate and graduate studios there.
