LEVEL 18 RESTROOM RENOVATION

Construction on the Level 18 Restroom Renovation at 1 Post OAK Central concluded in December 2024. This 415-square-foot interior renovation was registered with the Texas Department of Licensing and Regulation (TDLR) in August 2024, with a scheduled build window of 61 days. The project involved the alteration of existing interior buildout on the 18th floor of the building located at 2000 Post Oak Boulevard in Houston.

The estimated cost for this renovation was $190,000. This figure places the project below the median estimated cost of $250,000 for similar renovation and alteration filings in Harris County over the last 24 months. However, the cost per square foot of $458 is significantly above the county median of $80 per square foot, reflecting the specialized nature of high-rise restroom upgrades.

Project Details and Stakeholders

Parkway Properties served as the owner of record for this project. Ziegler Cooper was the design firm of record, responsible for the architectural and engineering aspects of the renovation. William T Winning was the registered accessibility specialist ensuring the work met state standards. The project was privately funded and carried out on private land for private use.

TDLR closed the project file in September 2026, which marks the end of the accessibility review process for this construction. The final inspection passed in December 2024, confirming that the work met the required codes before the file was officially closed. Parkway Properties has six other TDLR-registered projects totaling $1,936,000, including other renovations at 1 Post OAK Central and 11 Greenway Plaza.

Ziegler Cooper has been involved in six other registered projects totaling $859,450, with work completed at locations such as The Westchester and Heritage Plaza in Houston. The specific scope of this project was limited to the interior renovation of the existing interior buildout, distinct from larger structural changes often seen in commercial developments.

City of Houston permit records show seven building permits on file at this street address, issued between May 2026 and August 2026. These permits include descriptions for high-rise office restroom remodels and restaurant buildouts, indicating ongoing activity within the building. The TDLR record specifically covers the Level 18 restroom renovation registered in 2024.
