About Us
Allsopp Design, Inc. is a design/build firm located in historic Hamilton, Massachusetts. Our enthusiastic staff loves a challenge and enjoys taking on tough projects. Our understanding of the regulatory process allows us to work within sensitive areas so we can work with ease whether your project takes us to an island, atop a mountain or down the street.
Our Staff
Our seven person staff includes a creative design team and our own experienced construction crew of licensed construction supervisors.
Just as we strive for excellence in our projects, we are as concerned about the excellence of our employees. We encourage all team members to grow professionally. We have established a generous benefits package including 401(K), profit sharing, vacation time and education/ license reimbursement programs.
Principal & Affiliations

Jeffrey Allsopp established Allsopp Design, Inc. to offer quality service in a field where significant amounts of time and money are often lost due to poor communication between developer, architect and construction crew. ADI’s excellent reputation has been built upon a foundation of collaboration with our clients, a creative spirit and top quality workmanship. 

Jeff Allsopp’s commitment to excellence has earned him recognition and his memberships and affiliations support his focus on protecting the cultural, scenic, ecological and agricultural aspects of his community.
