The Harper is a 21-story, 56-unit condominium completed in 2023 on Manhattan’s Upper East Side. Designed by ODA and developed by IGI, the building references Art Deco and Bauhaus influences through a limestone-clad façade and a carefully appointed public lobby. Residences are exclusively three- and four-bedroom layouts with tall ceilings, white oak floors, solid-core doors, generous built-in storage and large windows; many homes include private balconies or terraces and views over planted gardens and treetops. Kitchens are custom Poliform designs with Taj Mahal quartzite surfaces, integrated Miele appliances and premium WaterWorks hardware; primary baths are finished in Crema Luna limestone and Namibia white marble with radiant heated floors and WaterWorks fittings. Mechanical comfort is delivered via a high-efficiency central VRF system, and units feature in-unit washers and dryers and abundant closet space. Common areas emphasize family and creative programming: a full-time doorman and resident manager welcome occupants to amenity spaces that include a fitness center, two roof lounges with grilling stations, children’s playroom, makers/art studio, teen lounge, music and podcasting studios, game room with screening and billiards, pet spa, and storage and laundry support. Exterior provisions include planted gardens and multiple outdoor entertaining zones. The Harper sits within a quiet, treelined block of the Upper East Side, offering a residential lifestyle oriented toward families and buyers seeking high-spec condominium living with a robust amenity program and proximity to neighborhood schools, parks and cultural institutions.
