A modern masterpiece set within the walls of supreme prewar elegance, 503 17th street is unlike any home amid or beyond its highly sought after Windsor Terrace location. The singular, completely renovated home expertly spotlights the classic details one expects in a Brooklyn townhouse while offering modern amenities that simply cannot be found elsewhere. From the outdoor shower to the perfectly manicured green roof, 503 17th street must be seen to be appreciated. Enter the parlor floor's custom mahogany doors to find a sprawling living space with its herringbone-patterned flooring bathed in both south and north-facing sunlight. The south-facing living room features a stunning decorative mantel, gorgeous crown and baseboard moldings, immaculately preserved original window shutters and a beautiful half-bathroom. Down the hall beyond the perfectly-placed wet bar lies an enormous, windowed eat-in-kitchen featuring a farmhouse sink, Smeg oven, honed Pietra Colombino countertops, Sub-Zero refrigerator, floating shelves and an exposed brick-framed window looking out over the divine green roof. Ascend the stairs to the home's second floor to find light streaming in from the skylight atop the stairs. In the rear of this level lies one of two primary bedroom options. This spectacular bedroom is framed by a semi-enclosed, exposed-brick laden private terrace that has to be seen to be believed. Meanwhile, its en suite bathroom features radiant heated floors and yet another skylight directly atop the luxurious deep soaking tub with a picture window looking down into the massive private garden. Another large, gorgeous bedroom, an office and a conveniently-positioned washer/dryer complete the second floor. Back down to the garden level lies two more swoon-worthy, enormous bedrooms lined with exposed brick walls, tin ceilings, exposed beams and wide plank white oak floors. The rear bedroom - which can also be used as the home's primary bedroom - features the most striking en suite bathroom one can find across the townhouse market. Best of all? This bathroom leads out to an enclosed portion of the extra deep backyard which houses your very own private outdoor shower. Moving outdoors, the expertly designed 50+ foot deep garden has been completely reimagined with all design and construction completed by multi-year "Best of Houzz Design" award winner Little Miracles Design. Featuring a variety of distinct spaces for cooking, dining, and relaxing, a large gravel drainage system beneath the pavers and a striking steel pergola from which a sun shade provides a space to cool off, the garden is the ultimate private respite from the city beyond. Among many other noteworthy upgrades, the residence features fully upgraded plumbing and electric, multi-zone central air conditioning and Nest-controlled heating along with heated radiant floors in the sprawling, full height basement. A true oasis set in a premier location, 503 17th street lies in the most desirable nook of idyllic Windsor Terrace. Prospect Park and the F & G trains are mere minutes away while shopping and dining options abound. Park Slope, meanwhile, is just a half-block walk.
