SAN MARCOS, TEXAS — Endeavor Real Estate Group has announced plans to invest $27.5 million to revamp Springtown Shopping Center, a retail center with low occupancy along I-35 in San Marcos between Austin and San Antonio. Endeavor purchased the center in November, at which point it was 10.5 percent occupied and split among four separate owners. The developer has signed leases with two anchor tenants. EVO Entertainment Group leased 34,000 square feet to build a dine-in luxury movie theater, bowling alley and event venue called The Spot. Gold’s Gym has leased 42,000 square feet.
