A project that will add Westchester County’s tallest building, a 44-story condominium and hotel tower called the Residences at Ritz-Carlton, topped out in October as part of a larger, two-building, $425 million development in White Plains, N.Y.

The tower – and a second building slated for a future phase – will both sit atop a 10-story podium containing the 123-room hotel, which also topped out.

Cappelli Enterprises of Valhalla, N.Y., is developing the overall two-tower project known as Renaissance Square, which will have 940,000 sq. ft. of hotel, residential, and retail space.

Work on the Ritz-Carlton, Westchester, which the Ritz-Carlton Hotel Co. of Chevy Chase, Md., is co-developing with Cappelli, began in March 2005, with George A. Fuller Co., a Cappelli affiliate, as construction manager. Costas Kondylis and Partners of New York designed the first tower, which is now taller than the county’s previous tallest building, the 39-story Trump Plaza in New Rochelle, which Cappelli also co-developed.

The 44-story Residences at Ritz Carlton tower will offer 213 units ranging from 1,200 to 5,200 sq. ft. in size at prices ranging from $700,000 to $3.5 million.

The hotel will include a luxury spa and fitness center, meeting and special-event rooms, and a street-front restaurant. Another restaurant is planned for the rooftop of the first tower.

Work began in September on a new cancer center for Yale-New Haven Hospital in New Haven, Conn. The $250 million facility is slated to open in 2010.

Designed by Shepley Bulfinch Richardson and Abbott of Boston, the North Pavilion-Cancer Hospital will have 112 beds and 12 operating rooms. Turner Construction of New York is construction manager on the 14-story, 511,000-sq.-ft. facility.

The steel-frame structure will also include three bridges and a tunnel that will connect it to existing underground corridors on the hospital’s campus.          

Battery Park City’s latest “green” condominium tower is rising at 70 Little West St. in Lower Manhattan after breaking ground over the summer.

The 33-story, 500,000-sq.-ft. tower, designed by Rafael Pelli of Pelli Clarke Pelli of New Haven, Conn., will contain 251 residential condominiums, 4,200 sq. ft. of ground floor retail space, and 40,000 sq. ft. for the Battery Park City Park Conservancy. The units will go on sale next year, though the developer, a partnership of the Albanese Organization of Garden City, N.Y., and Starwood Capital Group Global of Greenwich, Conn., has not announced its expected price scale.

The $310 million tower will feature a glass and terra cotta exterior in a curved shape, allowing for panoramic views of New York Harbor.

The project, on which Turner Construction of New York is construction manager, has multiple environmentally friendly features, such as an HVAC system that will condition, filter, and supply fresh air for each unit. It also has integrated solar panels that will produce about 5 percent of the building’s electrical load.

Another green feature is the use of wind-generated power to supply 35 percent of the building’s power needs as well as a blackwater recycling system to use bathroom and kitchen wastewater to re-supply toilets and provide replacement water for the HVAC system. Other amenities include a fitness center, pool, rooftop gardens, and lounge with a fireplace.

A set of three nine-story condominium buildings is set to open next spring in Palisades Park, N.J., on the banks of a conservation meadow, where residents will be able to view both the nearby preservation area and the Manhattan skyline.

Dubbed the Trio, the 474,707-sq.-ft. complex will have 196 units with floor-to-ceiling windows, including one and two-bedroom condos, some of which will include dens.

Tarragon Corp. of New York is developing the project with Daibes Construction of Edgewater, N.Y., serving as construction manager. The construction budget for all three buildings is $68 million.
