Building a home in Osterville and Oyster Harbors
Osterville is one of the seven villages of Barnstable, on the south side of town along Nantucket Sound, with its center on Main Street, the Wianno shore on East Bay, and Oyster Harbors, a gated community on Grand Island reached over a drawbridge.
A new house in Osterville is permitted by the Town of Barnstable, and the lot usually decides the order of the work. Near West Bay, East Bay, and the sound, the FEMA flood map and the Conservation Commission’s 100-foot buffer shape the foundation and where the house can sit. Most lots are on septic, so the Title 5 design sets the bedroom count before the plans are final.
Many new homes here replace an older house. Barnstable refers the demolition of a building more than 75 years old to its Historical Commission, so we file that early. In Oyster Harbors, we also confirm gate access, work hours, and any association requirements before we schedule trades and deliveries.

“Mussato Building Group has been a loyal and trusted partner of ours for over ten years and one hundred projects. Their professionalism and quality of work are second to none. We look forward to working with them far into the future.”

- Conservation Commission filing if the work is within 100 feet of a wetland, a pond, or a coastal bank.
- Plumbing, gas, and electrical permits pulled by licensed tradespeople, with town inspections at each stage.
- Barnstable Historical Commission review if a building more than 75 years old is being demolished.

Custom Home Builder in Osterville: FAQ
Who issues the building permit for a new house in Osterville?
The Barnstable Building Department issues it. Before that, the Board of Health approves the septic design, and the Conservation Commission reviews any work within 100 feet of a wetland or the shore. We prepare and file all of it.
Do you build custom homes in Osterville village and Wianno?
Yes. We build all over Osterville, including Osterville village, Wianno, and Oyster Harbors. Our base in South Yarmouth is about 12 miles away.
Do you build in Oyster Harbors?
Yes. Oyster Harbors is part of Osterville, so the permits come from the Town of Barnstable. Because it is a gated community, we confirm gate access, work hours, and any association requirements before we schedule.
Do you work with my architect?
Yes. We coordinate with your architect and engineer before construction and build from their drawings. If you do not have plans yet, we work with an architectural and structural design team.
