Potential for residential conversion in the heart of downtown Greenwich. Located just two doors from Greenwich Avenue and moments from the Metro-North train station, 37 Arch Street presents an exceptionally rare opportunity to create a one-of-a-kind in-town residence, mixed-use property, or continue as boutique commercial space. Situated within the Central Greenwich Business District zone, the property offers potential for residential, mixed-use, office, retail, or medical use (buyer to conduct all due diligence with the Town of Greenwich). This charming circa-1815 Federal-style building offers approximately 3,090 SF on an oversized 8,158 SF lot with the rare convenience of 8 on-site outdoor parking spaces plus 2 garage spaces - an extraordinary amenity for downtown Greenwich. The property is currently configured as executive office space and is in excellent condition, providing flexibility for investors, developers, or owner-users seeking immediate income while planning a future conversion or redevelopment. Prime walk-to-town location near Greenwich Avenue's luxury shopping, restaurants, parks, and transportation in one of Fairfield County's most sought-after downtown locations.
