Houston Center primarily. The Texas Eastern Corporation bought 32 city blocks and leveled all of it to build Houston Center, which was one of the largest private development projects ever envisioned. However, only a fraction of that land was ever developed to specification, leaving most of the land as vacant parking lots. Most of those blocks remained undeveloped as late as 2004. Four Houston Center was originally the designation of a 54 story office tower, which was never built. The name was subsequently adopted by the squat office building where the shops at Houston Center are.
