The Diamond House, at 170 East 77th Street, is a new condo conversion building on Manhattan's Upper East Side, offering luxury apartments for sale.

The lobby is bright and welcoming and features a translucent curved sculpture that echoes the curves of the custom canopy outside. A 24-hour doorman and concierge await your arrival and the cool slate floor and warm Anigre paneled walls provide a breathtaking backdrop.

The state-of-the-art, impeccably detailed apartments of The Diamond House combine modern elements with expansive open floor plans. Each of the newly renovated one- to four-bedroom homes boast the luxuries of solid oak wood strip floors in all rooms, bathrooms with limestone floors and glass and mosaic tile walls, beautiful Bulthaup kitchens with stainless steel appliances, including Sub Zero refrigerators and wine coolers, and advanced communication systems.
