The Avalon Multipurpose Center is a school gymnasium for the K12 school district in Avalon, Texas. The facility features a full-size basketball court, four locker rooms, synthetic glass front, foyer, restrooms, concessions, and seating for 720 spectators.

The Monolithic Dome is 124-feet (37.8 m) in diameter by 25-feet (7.6 m) tall atop a 12-foot (3.7 m) tall spray-in-place stem wall with a total height of 37-feet (11.3 m) and encompassing 12,000 square feet (1,122 m²) of floor area. Monolithic served as construction manager with Dome Technology as the dome contractor. The Airform was inflated on May 1, 2002, with the ribbon-cutting ceremony on November 14, 2002 — two months ahead of schedule and $50,000 under budget.
