Harriman combines the legacy of two design firms into an even stronger, more flexible and robust firm dedicated to enhancing the built and natural environment. Together we are a more comprehensive integrated, full-service practice in architecture, engineering, urban design, planning and landscape architecture. Harriman’s urban design and planning studio (formerly The Cecil Group) has a rich history of working on municipal projects in the Commonwealth of Massachusetts.

Harriman offers full services engineering including:

Harriman pursues creative partnerships to design relevant and innovative solutions to human needs. Our work is based on the belief that design is a collaborative human endeavor centered on knowledge, ingenuity, and beauty. Through practicing the art of architecture and the science of engineering, we create environments that honor context, embrace wisdom, and enhance well-being.
