Set within the historic Roberts-Quay House, this architect-designed residence pairs classic European elegance with contemporary living. Fully renovated in 2021, this 2-bedroom, 2-bath home offers a distinctive two-level layout with ceilings approaching 17 feet. Towering arched windows, abundant natural light, hand-cast plaster moldings, bespoke millwork, European white oak herringbone flooring, and a carved marble fireplace create a striking sense of character and scale. The elevated second floor is centered around a custom kitchen featuring an expansive Carrara Vagli marble waterfall island beneath an oversized skylight. Matching marble countertops and backsplash, custom cabinetry with knurled brass hardware, and a premium appliance suite create a refined yet highly functional space. Just beyond, the dining area overlooks the double-height living room below, creating a unique connection between the two levels. The primary bedroom is a quiet retreat with architectural millwork, custom built-in bookshelves, warm pendant lighting, and two generous closets. The primary bath has a boutique-hotel feel, with an oversized walk-in shower clad in blue Fireclay tile, custom solid-wood double vanity, and a Bosch stacked washer and dryer. The second bedroom, currently used as a nursery, offers a comfortable and versatile guest suite with its own full ensuite bath. Additional features include a marble-tiled entry with coat storage, private fire-escape access, generous under-stair storage, and a dedicated basement storage unit, along with an on-site bike room and trash facilities. Located in desirable Washington Square West, the home is an easy 8-minute walk to Whole Foods, Acme, and MOM’s Organic Market, with Seger Park just 6 minutes away. Jefferson and Penn hospitals are also conveniently located within a short walk, while the surrounding neighborhood offers an exceptional selection of shops, cafes, and restaurants. A rare opportunity to own a truly distinctive designer residence in one of Philadelphia’s most character-rich historic buildings.
