Residential condominium apartments at 170 East End Avenue, which is now in construction, will start at about $2 million for one-bedroom units.

The 110-unit building will have units ranging in size from 1- to 5-bedroom apartments.

It has been designed by Peter P. Marino + Architects and is being developed by Skyline Developers, LLC, of which Orin Wilf is a principal.

The new building will have an unusual facade of deeply-inset, multi-paned windows, many balconies with glass railings, and a center section facing East End Avenue clad only in glass. Vertically, the north and south wings on the avenue is broken into three sections with different pier arrangements in limestone-colored pre-cast concrete.

The two-story base on either side of the entrance will be rusticated limestone. Low-rise wings extend from the tower on the avenue along the side-streets framing a large communal garden.

When completed late next year, the building will have a garage and a children's recreation zone that includes a toddler paint room, a computer area for preschoolers, and miniature golf, video games and billiards for older children. The building will also have a squash court and an interactive driving range.

The building is expected to be ready for occupancy in Spring 2007.

The site was acquired by Skyline for about $650 a square foot, or about $165 million and an addition $20 million was spent for two nearby apartment buildings that are going to be refurbished and rented.

It is on the former site of the handsome, 14-story, red-brick Beth Israel Medical Center Singer Division between 87th and 88th Streets and it overlooks Carl Schurz Park to the east and Henderson Place to the south. The former hospital building was erected in 1929 as Doctors' Hospital and was acquired by Beth Israel Medical Center in 1987. Beth Israel is located on Stuyvesant Square at First Avenue and 16th Street and this facility was known as Beth Israel North and Beth Israel Herbert and Nell Singer Division and housed the Insall Scott Kelly Institute for Orthopedics and Sports Medicine and the Hyman-Newman Institute for Neurology & Neurosurgery. In 2001, the medical facility had about 210 beds and more than 800 employees. Beth Israel is operated by Continuum Health Care System, a conglomerate of hospitals that also includes Roosevelt Hospital, St. Luke's Hospital, Long Island College Hospital and New York Eye & Ear Infirmary.
