About this property
Set on just over an acre and including a transferable slip in the community marina, this stunning 4,800+ sq. ft. estate combines timeless French Provincial architecture with modern luxury. Designed by Elliot Johnson, AIA, and built by C&A Builders, this five-bedroom, five-and-a-half-bath home showcases exceptional craftsmanship and thoughtful design.
The grand entry opens to a formal dining room with a dramatic wall of windows and an arched brick ceiling. Across the hall, a 500+ bottle climate-controlled wine cellar makes a striking impression. The front office features a walk-in closet currently used as a gift-wrapping station and can serve as a fifth bedroom or guest suite. A powder room and an additional main floor private guest bedroom with ensuite bath and patio access complete the main gallery.
The gourmet kitchen includes Thermador Professional appliances, dual islands, a wine bar, and a spacious pantry. Two living areas offer versatility: a formal room with fireplace and built-ins, and a large family room with a cabana bath and access to the outdoor living area.
The primary suite is a peaceful retreat with white oak flooring, a sitting area, and direct pool access. The spa-like bath offers a soaking tub, oversized shower, dual vanities, and a custom walk-in closet with built-in dressers and a packing island. Upstairs features two ensuite bedrooms and a third living area.
Outdoor living shines with two covered patios, a flat yard, and a complete outdoor kitchen with grill, fridge, icemaker, and sink—perfect for year-round entertaining.
Vineyard Bay is a gated lakeside community featuring a private marina, renovated pool and cabana complex, clubhouse with gym and sauna, tennis and pickleball courts, and secure boat storage.
