About This Home

40 Grand Street

Nestled in the heart of historic Stonington Borough, this rare European-inspired countryside estate stands as a triumph of privacy, exclusivity, and architectural sophistication. A true showpiece of design, the property seamlessly fuses bespoke detail with modern luxury, surrounded by professionally maintained grounds long celebrated as a standout jewel of the Stonington Borough Garden Tour. The exterior grounds have been designed as an idyllic sanctuary for both grand-scale entertaining and quiet retreat, the meticulously manicured grounds offer a series of refined outdoor spaces. Broad stone terraces, intimate patios, and an elevated upper balcony look out over lush plantings, framing a crystal-blue in-ground pool that anchors the estate's resort-like outdoor ambiance. Upon arrival an open foyer greets guests offering seamless flow to both wings of the residence and opening directly onto a serene garden terrace. Fully renovated to cater to host and chef alike, the main kitchen features premium Thermador appliances, rich quartz countertops, and French doors leading to an expansive entertaining patio. A dedicated catering kitchen and butler's pantry streamline party logistics with effortless style. Separated from the kitchen by grand pocket doors, this sophisticated room is anchored by hand-painted wallpaper, a dramatic crystal chandelier, and one of the home's six fireplaces. French doors open out to the patio for fluid indoor-outdoor dining.
