With soaring, curved glass walls, this federal courthouse building at Niagara Square, a high-profile site in downtown Buffalo, N.Y., took four years to build. The 10-story, 265,000-sq-ft structure contains 10 courtrooms, several chambers and a 54-car underground parking garage. It will be home to the U.S. Bankruptcy Court, the U.S. Trustees, the Federal Defender and the U.S. Tax Court.
