The tennis center, planned for a site along Ridgeview Road, is being touted as the first one to be built with a retractable roof. Construction to date in the sustainable resort includes On the Rocks Restaurant, a locally owned coffee shop and a handful of artists' studios. Eighteen acres are dedicated for the development of boutique retail, with the remainder to hold about 100 condominiums, 36-room Copperhead Hotel, a bed and breakfast, two chapels, an independent living home, spa and the BurnLounge Recording Studio.

Lawrence Roddick, director of the Andy Roddick Youth Tennis Program for the Austin-based Andy Roddick Foundation, says the CastleRock Texas facility will be the main training center for the foundation's nationwide program for underprivileged children. "The CastleRock project is separate from what the foundation is doing, but they're kindly using their resources to help build the center," Roddick says. "It'll be the hub for programs we're hoping to build nationwide."
