Isis is a new construction condominium with a prime Upper East Side location at 303 East 77th Street. There's more to Isis than a plum spot on the Upper East Sde, though: the condominiums for sale at Isis offer luxurious amenities and one of the rarest luxuries in Manhattan real estate -- privacy. With spacious condos for sale and just 32 apartments spread over the building's 18 floors, Isis isn't just one of the most family-friendly condominium listings on the Upper East Side. It's one of the most private condo listings in Manhattan, period.

The renowned international designer, David Collins, created a contemporary marvel with the essence of a luxury condominium and a wide range of fine amenities.
