    Set mid-block on a beautiful tree-lined townhouse street in the heart of Park Slope, 448 6th Street is a mint condition 17'-wide single-family home. Built in 1901, this townhome features nearly 3,500 square feet of interior living space spread across four floors. Two distinct outdoor spaces include a large, south-facing garden and a finished roof deck with spectacular views of the Manhattan Skyline and New York Harbor. This stunning roof deck also features an irrigated rose garden, pergola and full kitchenette and bar. A grand stoop entry leads past a beautiful brownstone and brick facade with bay windows to an open parlor floor with soaring ceilings. Restored period details include moldings, parquet floors, and a wood banister. Anchored by a central staircase, this level features two distinct living spaces. The front parlor includes a gas fireplace with a marble mantle reclaimed from the Plaza Hotel. To the rear, the full-width living room is outfitted with custom millwork and coffered ceilings. Two sliding glass doors open to a balcony overlooking a unique south-facing double-height glass solarium, a truly one of a kind luxury finish. The parlor level also features a conveniently located powder room. Below, the garden level features a luxurious kitchen and sizable dining room. The kitchen features top-of-the-line appliances and a solid hand-carved marble sink that blends perfectly with the massive island. This space leads directly to the lower level of the solarium allowing for easy indoor/ outdoor dining. The solarium is also temperature controlled and has mechanically operated windows for circulation. The garden is paved in stone with a landscaped perimeter fence. The expansive dining room features a second gas fireplace and secondary entry below the stoop. The third level of this astounding townhome features one full-width bedroom to the front overlooking 6th Street. There are two sizable bedrooms in the rear and a centrally located full bathroom. The luxurious bathroom features a wet room with an enormous shower and clawfoot soaking tub. Above, the fourth level is a full-floor primary suite. A spacious bedroom with a bay nook sits in the front, and a walk-through custom closet leads to a luxurious bathroom with a double vanity sink, oversized rain shower, and a large opaque window. This allows light to flow in while maintaining privacy. An office sits just down the hall and offers a convenient private work space. The finished basement is configured as a spacious laundry room with ample storage. The finished roof deck is a stunning addition to a house designed for entertainment. The full kitchen and bar area is surrounded by seating, rose gardens, and a picturesque pergola. The remarkable views of the Statue of Liberty and New York City skyline are simply breathtaking. Located in prime Park Slope, on a charming tree-lined street, 448 6th Street is conveniently located only minutes from Manhattan and is surrounded by shops, cafes, and restaurants in all directions. This incredible brownstone awaits a discerning purchaser seeking a turnkey, luxurious and historic home.
