Our Process
01
Feasibility Study
Before you spend a dollar on construction, we navigate the "what-ifs." We conduct a comprehensive site audit and zoning analysis to confirm exactly what can be built on your lot, providing a clear budget and a predictable path forward.
Identify the Potential.
02
Design, Engineering, and Permitting
From Possibility to Permits.
We translate your vision into reality. Our team handles the heavy lifting of structural engineering and architectural design, creating a space that isn't just beautiful, but is optimized for your specific lot and built to the highest modern standards. During permitting, we are your professional advocate for City Hall, managing submission and approval quickly and efficiently.
From Foundation to Finish
03
Construction Management
We bridge the gap between paper and pavement. By partnering with vetted General Contractors, we ensure your project is built to your exact specifications. We monitor progress and quality, ensuring your ADU is delivered on time, on budget, and exactly as envisioned.
Financing Your ADU
Building an ADU is a significant investment. Most projects in Greater Boston run between $250,000 and $400,000 depending on scope, site conditions, and whether you're converting existing space or building new. The good news is that MA homeowners have more financing options today than ever before, and the state is actively adding new ones.
