A rare architectural gem in one of Prospect Heights’ most convenient locations, this move-in-ready one-bedroom duplex has been meticulously reimagined to blend pre-war charm with modern luxury. Fully redesigned with exceptional architectural vision, this home features charming pre-war detail, custom-built storage, top-tier appliances (Wolf, Miele, Liebherr), and grey-stained hardwood floors illuminated by recessed and cove lighting. The living room is open and inviting, with natural light streaming in through two beautiful arched windows. There is also the perfect setting for a dining table with room for a reading nook or a home office. The custom built kitchen serves as a design-forward focal point, outfitted with seamless white oak cabinetry, a waterfall-edge quartz island featuring a breakfast bar, and appliances including a Liebherr refrigerator, vented Wolf range and oven, Miele dishwasher, and a cleverly concealed microwave shelf. One flight below leads to a tranquil retreat, with original exposed brick and arched detail, high ceiling beams, and polished concrete floors — a calming space to rest and recharge. Storage is masterfully integrated through white oak built-ins, dual full size wardrobe closets, custom shelving, and under-stair compartments, offering abundant storage space. The bathroom offers a true spa-like experience, featuring a seamless walk-in shower with integrated trench drain, white oak vanity, linen closet, and a timed ventilation system for comfort and efficiency. A stacked Bosch washer/dryer rounds out the home’s extensive amenities. 521 Dean Street is a well-maintained, self-managed 10-unit co-op near Chelsea Piers’ new fitness club, Barclay’s Center, and acclaimed dining like Olmsted, Sofreh, and Radio Bakery.
