With an exceptionally high density of approximately 18,479 people per square mile, Cambridge, Massachusetts, presents a unique landscape for accessory dwelling unit (ADU) development, where maximizing space is paramount.

Our service is specifically geared towards the nuances of ADU construction, encompassing everything from initial design conceptualization to final occupancy permits. We focus on delivering functional, aesthetically pleasing, and code-compliant living spaces that enhance your property's value and utility.

Building an ADU is a custom project, so costs vary based on your specific choices. Site conditions are the biggest factor; if your land requires significant grading, utility extensions, or foundation work, those expenses add up quickly. Choosing high-end finishes, custom cabinetry, or complex roof lines will also push the budget higher compared to a standard design. Prefabricated units often offer predictable costs, while custom site-built structures allow for more flexibility but can be harder to estimate upfront. Exact pricing confirmed free on the call.

They can be detached or attached to the primary residence. We specialize in creating these compliant and valuable living spaces. Our focus is on meeting Cambridge's unique housing needs.

We meet all licensing and insurance requirements.
