A 10-year-old and fast-growing New York real estate brokerage is taking on more space at its Columbus Circle building.

Bond Real Estate New York has signed an eight-year renewal and expansion for 10,800 square feet at 1776 Broadway. The firm, which currently occupies the entire 19th floor, will also take over the second floor of the 25-story, 110,000-square-foot building, at West 57th Street. The asking rent for the lower floor was in the low $40s per square foot.

"They're doing well and hiring a lot of people," said Jeffrey Rosenblatt, the Newmark Knight Frank broker who represented the tenant in the transaction. "They hired 100 people last year, and plan to hire 75 to 80 new brokers soon."

Founded in 2000, Bond New York has four other Manhattan offices. The firm, which specializes in residential real estate services, plans to move into its additional floor in September.

Mr. Rosenblatt added that the firm was especially keen to occupy the second floor—which has a staircase accessible from the ground floor—because of its easy accessibility for clients who want to walk up for closings.
