Description

Live on top at 771 Union Street Apt #4. This is a quintessence Park Slope walk-up. Apartment 4 is located just 2 flights up and at the top of the building. Abundant light streams in through several skylights and windows ALL DAY LONG. It's also the perfect season to enjoy your WB fireplace with an exposed red brick facade located in the lovely and spacious living room. The kitchen is what cooks' dreams are made of and is large enough to reimagine into a chef's domain. There is plenty of room to add an island for an additional work surface or leave it open as is. The bedroom is large and has an adjacent room that can be used as an office or dressing space. Even this cozy room has a window with a lovely view. The full bathroom is accessible from within the bedroom. There are 2 large, deep closets that complete the bedroom space. There is original wide plank hardwood flooring throughout. Did we mention the private rooftop? It is newly redone to a blank canvas to create your extended living space. Build your dream rooftop oasis. Grow your own ingredients on your rooftop garden. The possibilities are limitless. This is an excellent building with recently updated windows and roof. The building has no mortgage. Free onsite laundry and storage are in the basement. Built in 1920, this co-op is self-managed. It is accessible to multiple modes of transportation and is closer to 6th Avenue. 771 is a sought-after location close to shopping and abundant dining, not to mention Prospect Park, Grand Army Plaza Greenmarket, the Brooklyn Museum and Library, and the lush Botanic Gardens. All showings are by appointment only.
