Isleworth Clubhouse Game Room Addition, Windermere, Florida. The building is a two-story addition with 14,450 SF including a cart area at the basement level and a game area at the elevated floor. The construction included structural steel for both a vaulted hip roof and a new clerestory, exposed heavy timber trusses and rafters, prestress precast joists and soffit beams at the elevated floor and light-gauge metal trusses at the clerestory roof. This project required extra attention to details and coordination among team members.
