Description

865 Union Street Adorning one of the most picturesque blocks in Park Slope, 865 Union Street exemplifies the artistic heritage and cultural fabric of this fabled neighborhood. This legal 2 unit residence currently used as a 1 family home was recently renovated with beautiful modern finishes, while retaining its original character with museum quality turn-of-the-century detail. Historically significant, this light and airy 20' wide neo-Grec brownstone was built over 1884-85 by Park Slope builder-architect John Magilligan. Built 4 stories and full-height with its gorgeous bay window accenting the front of the building. Exquisite mahogany wood, oversized Pier mirrors, original in-laid flooring throughout and fantastic banisters complete with original finials surround you from the moment you enter the front doors. With three rare exposures; the restored & original stained glass windows on the west side of the building bathe the middle of the home in dreamy light. The beautifully appointed kitchen, traditionally featured on the garden level, is completed by ebony floors, white custom cabinetry & millwork, creamy quartz countertops completed by a glass backsplash. The windowed master bath with original stained glass was custom designed and is spa-like in every way. Basket-weave marble flooring, an oversized soaking tub, double sinks with marble top and separate stall shower with glass enclosure and nickel fixtures throughout are luxurious and in keeping with the period of the house. Many modern conveniences have been seamlessly added to this home, such as two full sized washer/dryers (one on the lower level and one on the 3rd floor), a wet bar, the master en suite, the chefs kitchen as well as the custom built master walk-in closet. The professionally landscaped garden and deck off the formal dining room is lush and private. This tranquil setting is simply perfect for any size gathering or a simple family meal al fresco. 865 Union Street is a home for all seasons. Historic luxury in the heart of the North Slope.
