UBS Warburg officially completed its expansion effort that added 338,000-sf of space to its existing headquarters property at 677 Washington Blvd. The expansion includes an addition of 36,000 sf to its existing trading floor. The addition brings the total size of the trading floor to 103,000-sf, the largest of its kind in the world, UBS Warburg officials maintain. The floor can now accommodate up to 1,400 traders and staff.

"This expansion demonstrates our continued momentum in growing our investment banking and capital markets presence in the U.S. market," says John P. Costas, chief executive officer of UBS Warburg. "Today, we are one of the largest institutional traders and are making significant inroads across the full product spectrum."

In addition to the trading floor, the expansion program includes additional technical and related operations, as well as a seven-floor mechanical area and 500-car garage.
