Review of 170 East 77th Street by Carter Horsley

Diamond House at 170 East 77th Street is a pale-yellow-brick, mid-block 11-story apartment building with 70 condominium units. 

The building is half a block east of Lenox Hill Hospital. 

The building, which was erected in 1940, was renovated and converted to condominium in 2007 by Dominion Management.  Howard B. Spivak was the architect for the renovation.

Bottom Line

Diamond House has a central Lenox Hill neighborhood location that is very convenient to public transportation, shopping, restaurants, and schools. It was recently renovated and has a dramatic entrance canopy and lobby.


This mid-rise apartment building has a step-down entrance with a large metal-and-glass marquee that leads to a stunning, skylit lobby with curved glass walls. 

The building’s entrance is setback and the flanking wings have chamfered corners with bay windows.


The building has a very attractive, landscaped roof deck, and full-time doormen and concierges.  It also has a fitness center, sidewalk landscaping and storage facilities.


Apartments range in size from about 895 to 2,500 square feet.  Many of the units have sunken living rooms, beamed ceilings, kitchens enclosed with curved floor-to-ceiling partitions and washers and dryers. 

Kitchens have stainless-steel appliances by Sub-Zero and Bosch, wine coolers and dishwashers. 

Bathrooms have limestone floors, glass-enclosed showers, tea-for-two bathtubs and glass and mosaic tile walls. 

Apartment 10F is a one-bedroom unit with a foyer that leads to a 13-foot-wide dining area that opens onto a 21-foot-long sunken living room with a 12-foot-long terrace.  The apartment has an enclosed kitchen. 

Apartment 3C is a four-bedroom unit that has an entry that opens onto a 23-foot-long gallery/dining area overlooking a 25-foot-long sunken living room.  The 12-foot-square enclosed kitchen has a 12-foot-long dining alcove with a floor-to-ceiling curved partition next to the apartment entrance. 

Apartment 2B is a two-bedroom unit with an entrance foyer that opens onto a 12-foot-long dining area that overlooks the 21-foot-long living room.  The apartment has an enclosed, 12-foot-long kitchen and the bedroom has a bay window.


Built as a rental in 1940, the building was converted to condominiums by Dominion Management in 2007. 

Spivak Architects served as design architect and worked with interior designer Jacques Grange on the renovation of The Mark Hotel on Madison Avenue at 77th Street.
