Sales Launch at Tamarkin’s UWS School Conversion at 555 West End; See its Incredible Solarium and Library Apartments

Weeks after school started, sales have launched on the much-anticipated condo conversion at 555 West End Avenue, a former Catholic school. Originally built by William A. Boring in 1908, Upper West Side residents and visitors have long admired its architectural details, filigreed windows, limestone window bays, and turrets. Over 100 years later, with Landmarks’ blessing, architect and developer (in partnership with CL Investment Group) Tamarkin Co. restored the historic building to its former glory while adding a discreet penthouse and turning the institutional interior space into luxurious homes.

The 13 residences at 555 West End Avenue comprise spacious apartments with no more than two per floor, townhomes with private West End Avenue entrances, and two truly creative homes: The Library is a duplex apartment named for its previous use, but its 18.5’ ceilings, expansive Great Room, and five bedrooms and baths were not there in the school days. Elsewhere, the school’s gym was transformed into the Solarium Penthouse, a three-bedroom home with 20’ barrel-vaulted ceilings, a skylight, and a private terrace.

Regardless of layout, all interiors offer refined palettes, inviting entry foyers, bright and expansive Great Rooms, soaring ceilings, towering windows, excellent closet space, and abundant natural light. Kitchens are outfitted with hand-crafted cabinetry by Christopher Peacock, marble slab countertops and backsplashes, and top-of-the-line appliances. Marble master baths are adorned with Lefroy Brooks fixtures and white oak vanities by Christopher Peacock.

Amenities like a 24-hour doorman, fitness center, lounge, recreation room, private storage units, cold storage, and stroller valet were designed to meet the needs and comforts of modern New Yorkers. 555 West End Avenue is only two blocks from the 86th Street subway and pleasantly located between Central and Riverside Parks. The American Museum of Natural History, Beacon Theater, and much of the Upper West Side’s top dining and shopping are a short walk away.

Apartments at 555 West End Avenue start at $7.9 million. The Library is listed for $10.5 million, and The Solarium comes in at a stunning $18 million. At an average of $3,542 per square foot, the prices come in well above the Upper West Side average of $2,513 per square foot for similarly sized units (CityRealty listings). However, this may be warranted given the rarity of unique uptown conversions, the building’s celebrated architectural credentials both past and present, and residences unlike any other in the neighborhood, if not the city.
