About Us

An integrated architecture and construction firm

For more than 20 years, Polhemus Savery DaSilva has collaborated with individuals, families, and institutions to design and build exceptional homes and select civic and resort buildings that celebrate creative design and quality craftsmanship, honor their natural environments, and set the stage for lasting memories—for generations to come.

As a leading integrated architectural design and quality construction firm on Cape Cod and in coastal southeastern New England, we provide a highly collaborative process that is as special as the buildings we create. Our single-source approach ensures seamless communication among the project team—and with our clients—to ensure we meet deadlines, stay on budget, and deliver quality workmanship that realizes the client’s vision.


A cross-disciplinary leadership team

PSD was founded in 1996 as one of the region’s first fully integrated design and construction firms. Today, the team consists of about 50 employees. Under the stewardship of its leadership team, the firm has set a high standard of quality and service that continues to inspire our work—and elevate client expectations.
