Property Details
Description
ESTATE SALE — Offered is an exceptional 7,500 SQFT DOUBLE LOT with 5,625 SQFT of buildable FAR, located just steps from the water and offering beautiful views (including water views).
BACK ON THE MARKET.
This serene property presents extraordinary potential and undeniable value. Opportunities of this size are exceptionally rare on City Island, made even more compelling by its prime Bay Street location, with private beach access.
Do not let the current footprint deceive you — this home feels spacious, airy, and contemporary. The layout features three generously sized bedrooms, a large living room with bay windows and lovely water views, and an open-plan kitchen ideally suited for transformation into a chef’s kitchen. The adjoining bright and spacious dining room opens directly onto a large deck, creating an ideal setting for indoor-outdoor entertainment.
The potential is substantial; envision a second-story addition with sweeping water views, an additional deck, and even the possibility of a pool beneath the beautiful mulberry tree (inspirational only; all plans subject to DOB approval).
Not included in the square footage is a full basement with high ceilings, along with a finished den—perfect as a family room, home office, or guest suite—with the opportunity to add a full bathroom.
Estate sale — sold as is.
Additional Highlights:
• Low annual taxes: $7,013
• No flood insurance required
• Central HVAC
• Hardwood floors
• Private driveway
