What we do

Modular homes and structural insulated panel (SIP) homes combine precision-built components with on-site craftsmanship. Colin built his first modular home on Martha's Vineyard in the 1990s, and we have been refining the process ever since.

Why Green Island: Decades of modular experience on the islands — we handle the site, the set and the finish so the house is truly custom.

What's included

  • Modular: factory-built modules set on a foundation we prepare
  • SIPs: insulated structural panels for walls and roofs
  • Site preparation, septic, foundation and utilities
  • Set coordination, weather-tightening and close-in
  • On-site finish work, decks and porches
  • Landscaping to complete the property

How we approach the work

  1. Conversation and site visit — we learn the property, the goals and the constraints.
  2. Clear scope — what is included, what still needs to be decided and what information we need.
  3. Scheduled, coordinated work — one team managing the phases in the right order.
  4. Walk-through and follow-up — we finish what we start and stand behind it.
