Our specialty
Accessory Dwelling Units (ADUs)
Detached, attached and conversion ADUs designed and built start to finish — from feasibility through final walkthrough.
ADUs are our specialty. We help Rhode Island and Massachusetts homeowners turn underused property into space for family, guests, caregivers or rental income — with a single team handling design, permitting and construction.
Every ADU engagement starts with feasibility, not a sales pitch. We review your lot, zoning, utilities and access before design begins, so you know what your property can realistically support before you invest in plans.

- Detached backyard cottages and in-law suites
