Welcome home to 265 6th Avenue, in the heartbeat of Park Slope and zoned for William Penn, PS 321. This isn't just a home-it's a curated experience, from its structural rebirth to its final lighting fixture, this brownstone is a testament to uncompromising execution. This exceptional 19-foot-wide 4 story + finished basement (with custom dry sauna!) single family brownstone is the culmination of a 3 years, full-scale renovation-an uncompromising vision brought to life by the founder of a renowned New York based fashion brand who collaborated with award-winning interior designer Vasiliki Zannetis of Dash Design as well as the acclaimed architectural team at Archichord to transform a historic residence into a modern masterpiece of timeless design. While the townhouse is full of original charm and character like the brownstone facade, original cornice, ceiling moldings, medallions and 5 marble (currently decorative) fireplaces lovingly restored, you can sleep peacefully at night knowing that the structure and all mechanical systems were fully rebuilt between 2017-2018 including: LVL sister joists throughout all floors, a steel I-beam and completely new roof system, structurally engineered to support a rooftop hot tub and bulkhead, a new main waste line from street level to home, all-new Marvin windows and custom window partitions provide superior insulation (R-value of 4), as well as new electrical, plumbing and central heating and cooling systems. Enter your chef's kitchen, complete with waterfall Calcutta Santa Maria marble island, custom cabinetry imported from Spain, professional-grade appliances like an oversized Sub-Zero refrigerator, Wolf natural gas cooktop + convection oven and a Best Hood commercial vent system for the range. The large dining room just off the kitchen on the garden level that opens to an expansive backyard patio, landscaped by designer James McMurray, former host of HGTV's The Insider's Garden, featuring a 48"" Lynx professional grill wrapped in black granite and a bluestone facade and native plantings. With this impressive backyard as well as a parlor floor terrace complete with wet bar, Sub-Zero under counter fridge and wine fridge close by, you'll enjoy hosting indoor/outdoor dining and entertaining to your hearts content! Other unforgettable features of the home include: custom bathroom vanities and fittings by Perrin & Rowe, Waterworks, and Porcelanosa, Ann Sacks tile work, stone slab showers and steam shower with two luxury shower systems in the primary offer each bathroom a seamless, spa-like aesthetic. Engineered oak hardwood floors offer durability and style, while the walnut closet doors throughout add natural warmth. Statement Chandeliers from Circa Lighting and Restoration Hardware elegantly tie each room together. Period custom iron work, front doors and copper gutters highlight the history of the home. The entire fourth floor is dedicated to a grand primary suite-a private sanctuary featuring expansive sleeping quarters, spa-inspired bath, custom dressing areas, and serene treetop views. The 19' interior width allows joists to span without mid-wall supports-eliminating obstructive partitions and expanding usable living space which is highlighted in the expansive primary suite.
