Halcyon is a contemporary 33-story condominium tower completed in 2013 in Midtown East, Manhattan, offering one- to three-bedroom residences within a predominantly glass façade accented by warm limestone and bronze detailing. Units emphasize generous proportions with approximately ten-foot ceilings, floor-to-ceiling double-pane windows, wide-plank smoked oak floors, and high-end finish packages—Poliform cabinetry, Calacatta marble countertops and backsplashes, Miele and Sub-Zero appliances, plus built-in pantry and laundry rooms. Bathrooms are spa-oriented with white statuary marble, radiant heated floors in primary baths, deep soaking “tea-for-two” tubs, separate glass showers, and premium bronze fittings. Common interiors and services include a residential lounge and library, movement studio, sky lounge, playroom, a windowed fitness center with aqua spa and sauna, and a glass-enclosed lap pool around 50–55 feet. Landscaped courtyard gardens, outdoor kitchens and private outdoor spaces appear on select homes; on-site conveniences include bicycle storage and a garage. The building’s design aesthetic blends contemporary glass volumes with a warm material palette; it sits within Midtown East, providing direct access to major transit options, restaurants, and cultural destinations.
