A rare opportunity to own a beautifully renovated 1882 Gothic Victorian set on a landscaped .46-acre parcel in one of Sag Harbor Village's most charming and quiet locations.
Surrounded by historic turn-of-the-century homes, this architectural gem showcases timeless details: deep eaves, multiple gables, a striking turret, and dramatic Victorian windows that fill the home with natural light. The current residence offers approximately 2,500 SF of recently renovated living space, featuring 3 bedrooms, 4 full and one half bath, soaring 11-foot ceilings, a detached garage, and a 45′ × 12′ heated pool with an electric cover.
The property also comes with permits in place for a substantial expansion, a rare chance to create a true Sag Harbor Village compound while enjoying a fully renovated historic home today.
Approved plans let you expand well beyond the current home, adding bedroom suites, living space, a gym, a pool house, and a studio.
Plus a lower level, with room for additional bedroom suites, living space, and a gym.
With a powder room and an outdoor shower, beside the heated pool.
A flexible, standalone studio to complete the compound.
