CHICAGO-Allston Trading LLC has renewed and extended its lease for 26,000-square-feet at the 40-story One Financial Space. The firm occupies the 12th floor of the 1-million-square-foot office building at 440 S. LaSalle, which is currently 95% occupied. Building owner Behringer Harvard was represented by Jones Lang LaSalle’s Michael Curran, while Allston was represented by Matt Carolan and Bill Sheehy, also of JLL.

Built in 1985 and designed by Skidmore, Owings & Merrill, the building is known as the southern anchor of Chicago’s Financial District and is connected to the Chicago Board of Options Exchange, which in turn connects to the Chicago Board of Trade. Behringer Harvard bought the property from Beacon Capital Partners as part of a portfolio of four buildings in downtown Chicago for $832 million in November 2007. Asking lease rates at the building range from $21 to $22 per square foot net.
