The original architectural style was Brutalist (especially the central building), with a large open plaza paved with concrete and featuring wide shallow stepped levels.

CCF later went into bankruptcy, and the complex was successively owned by Mitsubishi Bank, the Prudential Life Insurance Company, and Beacon Capital Partners, until it was repurchased by MIT in 2001.
