Blending Centuries
Roosevelt Island Development Merges New and Old Towers
by Natalie Keith
A new 500,000-sq.-ft. apartment complex on New York City's Roosevelt Island is wrapping various construction specialties into a development that will preserve an unusual slice of the city's history.
The new $170 million Octagon development on the East River isle blends the renovation of an historic structure with two new 14-story apartment towers.
"The most challenging aspect of the project was the restoration of the Octagon Tower," said Bruce Becker, president of Becker + Becker Associates of Fairfield, Conn., the project's architect and developer.
The renovation of the five-story Octagon Tower brings back an 1841 building designed by Alexander Jackson Davis. It first served as entry and administrative space for the New York Lunatic and Pauper Society and later as Metropolitan Hospital. It was vacated in 1954 and, after fires in 1982 and 1999, only the eight exterior walls remained.
Work began in November 2004 with New York-based Gotham Construction as general contractor on the effort to restore the 30,000-sq.-ft. historic building and build the two towers, one 230,000 sq. ft. in size and the other 250,000 sq. ft. The first residents moved into a completed portion of one tower on April 17, but work will continue on the rest of the project through late fall.
Upon its completion, the complex will have 500 units, 400 of which will rent at market rates, which under a first-year promotion is $1,690 monthly for studio apartments with a home office, $1,800 for one-bedroom units, $3,015 for two-bedroom units, and $3,798 for three-bedroom units. The remaining 100 units will be reserved for middle-income individuals under an affordable housing program.
The most noteworthy aspect of the old building, which is listed on the National Register of Historic Places, is a central "flying" circular staircase that Charles Dickens wrote about it in his travelogue, American Notes.
While the project team restored the exterior to its classic look, it used a modern interpretation in reconstructing a new seven-story staircase rising into the atrium. The main support is a steel tube positioned in the center that runs up the backbone of the entire spiraling stairway, said Kevin Murphy, project manager for Gotham.
In addition to the restoration tasks, the project has various sustainable design features because the developer is seeking a silver rating under the U.S. Green Building Council's Leadership in Energy and Environmental Design program. The team is using locally produced materials, recycling construction waste, and installing 250 rooftop photovoltaic panels that will generate 50 KW - enough to power the development's common areas.
With such features, the Octagon will use 35 percent less power than the maximum amount allowed for its size under the city building code, Becker said.
The project team had also considered using geothermal technology to address power needs but scrapped that plan after drilling two 1,500-ft. test wells and discovering that the water flow would be inadequate, Gotham's Murphy said.
