About Hammer Architects

Hammer Architects, with offices on Cape Cod and in Cambridge, Massachusetts focuses primarily on residential design. Our portfolio includes new homes, as well as renovations and additions that often require a sensitive integration with an existing historic or architecturally significant house. Our goal is to craft well designed buildings that are appropriate to their surroundings, make a positive contribution to their environment and are a joy to live in.

Our work is widely recognized for its design excellence and has been published in numerous books, blogs and magazines.

The size of our firm allows us to maintain close collaborative relationships and provide substantial principal involvement in all phases of our commissions. Our technical commitment enables us to arrive at innovative solutions, in response to our clients’ budgets, schedules and program objectives, and our experience permits us to discover creative ways to fulfill our clients’ expectations.

"Mark and Don designed a new summer house for us in Truro MA and updated and renovated our home residence in a suburb outside Boston. We have found that they not only have a great eye for contemporary design but also create plans that are practical and reflect our needs for space and livability. We strongly recommend them!"

"Working with Mark Hammer and Don DiRocco was a lot of fun, easy and inspiring. They listened very well to our ideas, translated them into a viable project that grew organically into a wonderful house. We could never have imagined how beautiful our new house fits into its environment."

"We worked with Hammer Architects on a substantial renovation and addition of a modern house on the outer Cape. We could not be more thrilled with the design! The house went from a nonfunctional, awkward single story plus basement to a beautiful and practical two-story that one would think should have always been this way. Mark Hammer and Don DiRocco were able to create a design that perfectly incorporated the existing structure and windows, and the end result is stunning (light, flow, everything!). In addition to the design phase, Hammer Architects was heavily involved in the construction phase and helped with landscape design. Mark and Don are great to work with and are true professionals."
