The interior renovation of a 12,296 sq ft office suite on Level 10 of Pennzoil Place in Houston has not yet recorded a final inspection with the Texas Department of Licensing and Regulation. The project, filed by Kusa Inc., dba Karoon Energy, involves the complete alteration of the space within the building’s Central Business District location.

Located at 700 Milam Street, Suite N1000, this work is classified as a Renovation/Alteration. The scope covers the design and installation of new partitions, ceilings, lighting, and finishes, along with updates to mechanical, electrical, and plumbing systems. The estimated cost for this private project is $1,750,000, which calculates to $142 per square foot.

Pennzoil Place is a prominent two-tower office complex in downtown Houston. According to Wikipedia, the building consists of two 36-story structures designed by Philip Johnson and John Burgee. The Architect's Newspaper noted that the property was commissioned by Hines for lease to oil companies and has been listed for sale. The specific suite undergoing renovation is part of this larger Type 2A office tower.

Inventure is the design firm of record for this project. William T Winning serves as the registered accessibility specialist. The project was registered with TDLR in January 2026, and plan review was completed in February 2026. Construction was scheduled to begin in February 2026 with a completion date of May 2026. Because the final inspection has not been recorded, the current status of the site remains unconfirmed in the public record.

City of Houston permit records show four building permits issued at this street address between January and May 2026. These permits include a 12,296 SF high-rise office remodel and a high-rise office restroom remodel, both referencing the 2021 International Building Code. The permits also cover the demolition of interior non-load bearing, non-fire rated walls. These local records align with the scope of work described in the state filing.
