Fannin Tower LTL - Level 23 in Houston, TX

Texas Children's Hospital is renovating 21,180 square feet of space at 6624 Fannin Street in Houston's Medical Center Area. The project, filed under the name Fannin Tower LTL - Level 23, involves an interior buildout for a new clinic. This renovation is scheduled to finish in December 2027, with construction work starting in April 2026. The total estimated cost for this alteration is $7,771,484, which works out to $367 per square foot.

Powers Brown Architecture serves as the design firm of record for this project. The registered accessibility specialist is Meghan Broussard Simecek. TDLR completed the plan review process in February 2026, clearing the way for construction to begin. The project is privately funded and located on private land for private use. It is one of several major initiatives by Texas Children's Hospital in the region, joining other projects such as the Pavilion for Women and the Mark Wallace Tower.

At 21,180 square feet, this buildout is significantly larger than the median renovation size in Harris County, which is 4,000 square feet. The estimated cost also sits in the top quarter of renovation filings in the county, exceeding the median of $250,000. The scheduled build window of 615 days is longer than the county median of 92 days, reflecting the complexity of a full clinic interior buildout. The cost per square foot of $367 is above the county median of $80, consistent with high-end medical facility standards.

City of Houston permit records show four building permits on file at this street address, issued between February and March 2026. These permits describe a clinic office buildout and a high-rise clinic office remodel, aligning with the TDLR filing scope. The area is part of the densely developed Medical Center district, where other registered projects include renovations at Houston Methodist and the Hilton Medical Center. The construction activity will take place within a neighborhood with a median household income of $79,415, according to U.S. Census estimates for ZIP code 77030.
