Texas Children's Hospital is renovating 20,908 square feet of interior space at 6624 Fannin ST in Houston. The project, registered with TDLR as Fannin Tower LTL - Level 21, involves the build-out of a new clinic space within the Medical Center Area of Harris County. This substantial alteration is estimated to cost $7,691,860, which works out to approximately $368 per square foot. The filing specifies that the work is a renovation and alteration of existing facilities to create dedicated clinical areas.
