Get a Free QuoteGreenwich is one of the most architecturally diverse markets in Fairfield County. Old Greenwich and Riverside are dense with post-WWII colonials and cape-cods — these homes are in high demand, which means remodels are investment decisions with clear market returns. Kitchen and bath upgrades in these neighborhoods consistently recapture 70–85% at resale in Greenwich's price environment.
Cos Cob's Victorian and craftsman homes require contractors who understand period woodwork, plaster walls, and the material choices that preserve character while meeting modern code. We don't spec these homes the same way we'd spec a 1980s ranch — and we're upfront about the difference in cost when original materials need preservation.
Backcountry Greenwich estates on 2–10 acre lots are a different scope entirely. Additions here involve significant structural work, long permit reviews with Greenwich's Building Department, and sometimes ARB (Architectural Review Board) involvement for properties with deed restrictions. We've done this before — permit timelines here can run 6–8 weeks for additions.
Greenwich's building department at 101 Field Point Rd is thorough. Plan submissions for additions require architectural drawings and often engineer sign-offs. We manage the entire submission and revision process — you don't call the building department.
Kitchen remodels in Greenwich typically range from $45,000 to $100,000+. Old Greenwich and Riverside homes frequently invest $60,000–$90,000 for full custom kitchen remodels. Backcountry Greenwich estates can run higher with premium appliances and custom millwork. We provide detailed cost estimates upfront with no commitment required. See our kitchen remodeling page for full pricing detail.
Yes — structural, electrical, and plumbing work in Greenwich requires permits from the Greenwich Building Department at 101 Field Point Rd. Greenwich has one of the more thorough permit review processes in Fairfield County, particularly for additions and structural changes. Permit timelines range from 3–6 weeks.

Home additions in Greenwich typically take 4–6 months from permit approval to completion. Greenwich's permit review process for additions can run 4–6 weeks (longer for Backcountry properties with deed restrictions or ARB involvement) before construction begins. We manage the entire process including architectural review, permit submission, and final inspections.
