What we do
Detached garages, barns and workshops give you room for vehicles, equipment, hobbies and storage. We build them to match the main house and to stand up to coastal weather.
Why Green Island: Outbuildings built with the same care as the main house — designed to match and built to last.
What's included
- Detached and attached garages
- Barns and carriage houses
- Workshops and studio space
- Foundations, slabs and sitework
- Roofing, siding, doors and windows to match the home
- Lofts, storage and finished space above
How we approach the work
- Conversation and site visit — we learn the property, the goals and the constraints.
- Clear scope — what is included, what still needs to be decided and what information we need.
- Scheduled, coordinated work — one team managing the phases in the right order.
- Walk-through and follow-up — we finish what we start and stand behind it.
