Newly constructed and ready to enjoy, this exceptional waterfront estate on the Bumps River represents the finest of Cape Cod living. Combining an unrivaled setting with state-of-the-art luxury, the property features a resort-like swimming pool and cabana, a boathouse with a float for non-motorized crafts, and a deeded beach lot on Long Beach. The open floor plan seamlessly flows from a fireplaced living room with coffered ceilings to a gourmet kitchen with a Sub-Zero refrigerator, Wolf range, and Danby natural stone counters. Glass doors line the waterside of the home, opening to an expansive Phoenician Buff stone terrace surrounding a Pebble Tec pool and spa. The first-floor primary boasts 2 walk-in closets and a luxurious bath with a freestanding soaking tub. Four en suite bedrooms, a family room, and an ipe deck occupy the second level, with bonus space above. A bedroom suite over the garage accommodates guests or staff. Located minutes from everything Osterville has to offer.

ADU Potential

Massachusetts allows one accessory dwelling unit by right in single-family zoning districts statewide (M.G.L. c. 40A §3; 760 CMR 71.00, effective Feb 2025). Estimated maximum ADU size for this property: 900 sq ft (the lesser of 900 sq ft or half the 8,387 sq ft principal dwelling). Lot size: 113,256 sq ft.

Based on listing data, which indicates the property type — not the zoning district. Local dimensional, septic (Title 5), and historic-district requirements still apply. Not legal advice — verify with the municipality.
