125 E 84Th St

Built in 1927, this intimate nine-story prewar cooperative on the Upper East Side contains a small collection of thoughtfully proportioned homes—primarily studios and one-bedrooms within a total of 17 units. The façade and massing reflect traditional 1920s Manhattan townhouse-scaled apartment houses, while interiors present a mix of preserved prewar details and updated finishes across apartments. Ceiling heights vary by unit; many homes retain herringbone hardwood floors, decorative moldings, beamed ceilings, and working wood-burning fireplaces alongside modernized kitchens and windowed bathrooms in renovated units. Common areas and services emphasize full-service living: a 24-hour doorman/concierge, a live-in resident superintendent, bike room, central laundry, and private storage bins that transfer with units. A planted roof deck and limited private outdoor spaces add gardening and terrace options for residents. The building accepts pets and permits pied-à-terre ownership in many units, with flexible board policies (including allowance for some LLC purchases and 50% financing in some listings). Located on a quiet tree-lined block just off Park Avenue, the coop places residents steps from the 4/5/6 trains, Central Park, museums, restaurants, boutiques, and neighborhood schools, delivering a classic Upper East Side lifestyle that balances prewar charm with full-service conveniences.
