At Hampden Design + Construction, our goal is to help homeowners create comfortable additions and beautiful custom homes. We appreciate the enormity of this decision and will treat your home with the attention and respect it deserves.

About Us

Award winning, Hampden Design + Construction was founded in 2003 by Principal and owner, David Cohen. Since its inception, Hampden Design + Construction has earned several notable distinctions, including a 2020 Best of Boston Home award by Boston Home Magazine, Best General Contractors in Newton by GC Magazine, and a 2021 Readers’ Choice award winner for Contractor/Builder by The Boston Herald. In addition, Hampden’s projects have graced the pages of some of the region’s top design publications, along with being featured on PBS’s award-winning program “This Old House.”

Commitment to Quality

The majority of our business consists of residential projects – either renovation of rooms within an existing footprint or additions which blend seamlessly with your current home. We are ever-vigilant not to over-extend ourselves and compromise our commitment to quality and value.

A True Partnership

Your choice of builder is of critical importance. Depending on the scope of your project, we’ll be spending anywhere from a few months together to a few years together. We need to feel comfortable with each other and you need to feel confident that we can accomplish your goals.

About David Cohen

David, a licensed Construction Supervisor and Building Inspector, grew up always building, tinkering, and taking things apart. After getting degrees in business and economics, David worked for an investment firm, but soon realized sitting at a desk was not for him. Leaving the 9-5 behind, David joined the family business, ‘Hampden Automotive,’ a company that his grandfather started on Hampden Street in Jamaica Plain. There, David would learn the importance of a solid work ethic and hard labor. After Hampden Automotive went out of business, David focused back to his passion he decided to join the construction world, turning his hobby into a career and carrying on the family name. Thus, Hampden Design + Construction was born. Today, David resides in Newton, where he was born and raised, with his wife and three kids, living – and building – the white picket fence.

Priding himself on being a great listener to both the client and the home, David provides nothing but respect, hard work, and open communication throughout the design and construction process. “Builders, in general, are one of the last professions that start with nothing and create something,” states David, “Anybody can build a box, four windows and a ceiling, but how you create these unique spaces is a one of a kind process.”

One Tree Planted Partnership

It takes more than 20 full-grown Douglas Fir Trees to build every 1,000 square feet of structure.* At Hampden Design + Construction, it is our goal to help give back to the earth what we take from it when we build and renovate homes. We’re happy to be partnering with One Tree Planted, a non-profit organization focusing on global reforestation, where we pledge to plant a minimum of 1200 trees in North America forests each year.

This philanthropic effort is in line with Hampden’s commitment to protecting the environment and promoting sustainability with best building practices. In addition to supporting the reforestation effort, our goal is to help spread the word about this worthwhile organization and inspire others to help do something positive for our environment.
