Cape & Islands Builders Group, Inc.

Cape & Islands Builders Group works at the ambitious end of residential building: custom homes, passive and net-zero houses, and accessory dwelling units, run out of Centerville as a design/build firm covering Barnstable County and the islands. Founder and president Kian Bonvan is a Phius Certified Builder for Cape Cod, the islands, Plymouth County and southeastern Massachusetts, and the company says he works directly with clients at every step. The company traces its start to 2010 and puts itself at 16 years in business. In a June 2024 Better Business Bureau 'Behind the Business' feature, Bonvan described buying out the two tradesmen brothers he started the company with, and said the business grew on customer referrals. Alongside new construction, the services it lists include kitchen and bathroom renovations, whole-home renovations and ultra-energy-efficient custom homes. Its stated service area reaches most of the Cape — Bourne, Brewster, Chatham, Dennis, Eastham, Falmouth, Harwich, Mashpee, Orleans, Provincetown, Sandwich, Truro, Wellfleet and Yarmouth — and it appears in the Cape Cod Chamber of Commerce directory. Its Massachusetts home improvement contractor registration, #180161, is active on the state registry under the company name. This is a firm for a whole house, an ADU or a high-performance build, not a small repair call. Before signing, ask to walk a finished passive or net-zero project, and get the design fees, allowances and the construction schedule spelled out in the contract.
