📰About Idemitsu
The renovation project at Four Oaks Place in Houston is complete. TDLR closed the project file in August 2026, marking the end of the accessibility review process for this construction. The work involved a 7,854 sq ft office renovation at 1330 Post Oak Blvd. Suite 1100, with an estimated cost of $744,000. This placed the project in the top quarter of cost for similar renovation filings in Harris County, which had a median estimated cost of $250,000.
Scope and Specifications
The filing described the work as an office renovation including updates to lighting, power, and finishes. The project was registered with TDLR in October 2025, with plan review completed the same month. Construction began in October 2025, and the scheduled build window of 127 days was longer than the county median of 92 days. The final inspection passed in April 2026, confirming that the construction met the required standards before the file was closed.
Four Oaks Place Operating LP served as the owner of record, while Inventure was the design firm of record. Janel Carona Bloom was the registered accessibility specialist for the project. The work was privately funded on private land for private use.
Context and Comparison
The estimated cost of $744,000 for the 7,854 sq ft renovation resulted in a cost of $95 per square foot. This figure is above the county median of $80 per square foot for similar renovation and alteration projects. The owner, Four Oaks Place Operating LP, has five other TDLR-registered projects in Houston, with costs ranging from $185,000 to $1,078,000. Inventure, the design firm, has six other registered projects in the area, including work at 515 Post Oak and 1801 Post Oak.
Third-party descriptions of the building complex vary slightly on management, with some sources citing CBRE and others Transwestern, but all identify it as a prominent office campus in Uptown Houston. The specific suite renovation covered here is one of several projects associated with the Four Oaks Place address. City of Houston permit records show four building permits issued at this street address between April 2026 and August 2026, including high-rise office remodels. These permits align with the timeline of the final inspection and file closure for the TDLR-registered work.
