Close enough for Sunday dinner. Independent enough to feel like home.
Most of the ADUs we build are generational — a place for a parent on their own to live next door. Private, single-level, built for the way your family actually lives.
The law finally caught up with the need
As of February 2025, Massachusetts allows accessory dwelling units up to 900 square feet by right in most single-family zones — no special permit fight, no town meeting. (Town-specific requirements still apply; we handle the permitting and know what each of our towns expects.)
That changed everything for families who’d been putting this off. A parent keeps their independence and their own front door; you keep them close. And when the time comes, the space flexes — guest house, home office, or rental income in a market that needs it.
Detached Cottages
A small home of its own in the yard — the classic generational setup, with full kitchen, bath, and laundry.
Garage Conversions
The structure’s already there. We convert and connect it — insulation, systems, and finishes to full-home standard.
Attached Suites
An addition with its own entrance — closest connection, easiest care, still separate front doors.
Typically a 4–5 month project
From design and permit to move-in, a typical SCB ADU runs four to five months. We handle design, permitting, and construction — single-level living, accessibility options (zero-step entries, wider doors, curbless showers) built in from the start, not retrofitted later.
Considering something bigger? See the Family Compound at 11 Walnut & Julia Lane — the same multigenerational idea, at neighborhood scale.
