The Harper is a 21-story condominium on Manhattan’s Upper East Side completed in 2023. Designed by ODA and developed by IGI, the building pairs Art Deco references with Bauhaus-inspired minimalism, expressed through a limestone-clad façade and a carefully finished lobby. Residences are limited to three- and four-bedroom layouts spanning generous floor plates; interiors emphasize gallery-like entry foyers, wide great rooms, and private outdoor spaces ranging from balconies to substantial private gardens. Apartments feature high ceilings, white oak flooring, Poliform-designed kitchens with Taj Mahal quartzite surfaces and Miele integrated appliances, solid-core doors with Valli & Valli hardware, side-by-side washers and dryers, and VRF climate control. Bathrooms use Crema Luna limestone and Namibia white marble, with radiant radiant-heated floors and premium WaterWorks fixtures. Building amenities include a full-time doorman, a fitness center with modern equipment, a children’s playroom, makers studio, music studio, teen lounge, multiple outdoor terraces and garden areas, and resident storage; outdoor cooking and barbecue facilities are provided at floor or building level. The property supports private appointments and immediate occupancy, and its location places it within the Upper East Side’s residential streetscape, close to neighborhood schools, parks, and transit options.
