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. The formal living room leads out to a private patio, a hidden wet bar, and an sun-drenched four-season sunroom. Down the hall, a cozy den features a built-in entertainment system and gas fireplace, while an adjoining private office offers a tranquil space for work or quiet reflection. Tucked away for maximum privacy, the main primary suite features French doors to a secluded terrace, a generous dressing room, and a spa-inspired bath equipped with a steam shower, jetted soaking tub, and dual vanities. The second floor of the main residence offers three generously proportioned, tastefully appointed bedroom suites. Each room captures breathtaking vistas of the manicured grounds through oversized windows, cozy sitting nooks, and access to a panoramic upper balcony. Positioned above the attached two-car garage is an equally exquisite, fully independent primary suite. Complete with custom built-in shelving, a large dressing room, and a picture-perfect bath, this secluded suite provides an ideal layout for a guest retreat, au pair quarters, or long-term family visitors. While the upper floors offer quiet respite, the lower level is dedicated to health, leisure, and late-night indulgence. A fully functioning "modern speakeasy" with wet bar is set beside a dedicated wine cellar, perfect for tasting rare vintages. The private cinema is a deep-seated, cozy theater space built for movie nights at home. Additionally, a versatile recreation space is ready for your private gym or fitness studio. An unparalleled sanctuary of style, detail, and location, this extraordinary property represents one of the finest coastal estate offerings in Southern New England. Embodying effortless luxury, this residence is being conveyed fully furnished, curated with precise detail and refined aesthetic poise. Acquiring this turn-key sanctuary allows the next owner to immediately experience its elevated lifestyle without the need to recreate its perfection-every carefully chosen piece, thoughtfully placed finishes, and harmonious interiors are already in place, awaiting your arrival.
