The plan for the Boston Sports Institute project consists of four buildings: an ice rink, field house, pool and entry. Clear spans provide uninterrupted space for the rink, pool house and field house, while mezzanines wrap shoes areas and offer patrons viewing stands as well as a running track. Below the mezzanine space was provided for locker rooms, a warm pool, offices and other support spaces. The 101,842-square-foot building was erected on a constrained site where workers only had access to three sides of the building.
