Halcyon at 305 East 51St Street Building Details
Halcyon is a striking 32‐story condominium tower completed in 2013, featuring 123 premier residences nestled in the serene yet well-connected neighborhood of Turtle Bay in Midtown East. Its architecture is a balance of dramatic modernity and refined materials: a predominantly glass facade with sweeping views in nearly every direction, anchored by a warm limestone base and bronze metalwork that add elegance and texture to its silhouette. Residences range from studios to four‐bedroom layouts, including duplex penthouses and units with private outdoor spaces, tailored for sophisticated New York living with generous proportions and high ceilings.

Inside, the Halcyon's homes are defined by thoughtful design and high-end finishes. Many units feature floor-to-ceiling, double-pane windows, wide‐plank smoked oak flooring, and custom Poliform kitchens with lacquer cabinetry. Counters and backsplashes are Calacatta Gold marble, complemented by premium appliances from Miele and Sub‐Zero. Bathrooms are luxurious retreats with statuary marble, deep soaking tubs, glass‐enclosed showers, radiant heated floors, and bronze fixtures. Each home also includes an in‐unit washer/dryer and individual climate control, enhancing comfort, privacy, and convenience.

The amenities are exceptional, designed to elevate daily life. A 52‐foot indoor heated pool anchors its wellness offerings, along with a spa featuring steam room and sauna facilities, a fitness center with floor‐to‐ceiling windows offering city views, and yoga or movement studio. Shared social spaces include a sky lounge with catering kitchen, library opening into landscaping and courtyard, media / dining salons, a children's playroom, golf simulator room, roof terraces, and landscaped outdoor terrace areas with fire pits. Full‐service touches include 24‐hour doorman and concierge, private storage, a parking garage (available for a fee), and pet‐friendly policies that allow cats and dogs with board approval. Nestled in Turtle Bay, Halcyon offers both peaceful residential ambiance and swift access to Grand Central, the United Nations, upscale dining, shopping, and the finest cultural institutions.
