Almost 16 million square feet is currently listed as available in large blocks in 68 office buildings in Manhattan, according to Colliers ABR, a commercial brokerage firm. That is nearly double the space available a year ago, both in terms of the number of large office blocks — which in New York usually means 100,000 square feet or more — and in terms of total square feet.
Those figures are widely expected to go much higher, said Robert L. Sammons, the managing director of research for Colliers ABR. He said it was difficult to get a handle on exactly how much space financial companies alone might put back onto the Manhattan office market over the next year or so.
