N.Y. museum to expand by 22%

The Museum of the City of New York announced a $28-million expansion that will add 23,000 square feet, including a renovated lobby and a 2 1/2 -story addition at the rear of the existing building.

The museum has a collection of more than 1.5 million objects and images available to researchers and hosts exhibitions on various aspects of the city’s history.

The expansion, which will increase space by about 22% and is slated for completion in 2008, was designed by Polshek Partnership Architects, which created renovations of the Brooklyn Museum and the American Museum of Natural History.
