The first addition to Rec Hall was completed in 1953 at a cost of $1,021,310. A 100-foot expansion of the arena was part of the 1963-64 renovation and increased seating capacity from 5,000 to 7,200. Scoreboards, especially designed for Rec Hall and adaptable to several sports, also were installed. Recent adjustments in seating have reduced the capacity to 6,502.
