1500 Dragon Street Demising Walls

DDD Portfolio Holdings LLC is installing tenant separation walls and a new egress stair at 1500 Dragon Street in Dallas. The renovation covers 23,000 square feet within the existing facility, with an estimated cost of $100,000. This specific scope of work focuses on interior partitioning and emergency exit improvements rather than structural expansion or new construction.

The project was registered with TDLR in September 2026, and plan review is pending. Construction is scheduled to begin in October 2026, with completion targeted for November 2026. This compressed timeline reflects a focused alteration rather than a full build-out, allowing the work to proceed rapidly once approvals are finalized.

Design and Oversight

Rees serves as the design firm of record for this renovation. Stephen A Meyer is the registered accessibility specialist ensuring the new egress stair and separation walls meet Texas accessibility standards. The private funding source is DDD Portfolio Holdings LLC, which owns the property and is undertaking the work on private land for private use.

Context and Scale

At $4 per square foot, this project’s cost is significantly below the Dallas County median of $72 per square foot for similar renovation filings. The scheduled build window of 31 days is also shorter than the county median of 92 days. While the total estimated cost of $100,000 is below the county median of $248,661, the project’s scale is driven by the specific need to update egress and tenant boundaries within the existing 23,000-square-foot structure.

The surrounding ZIP code 75207 has a population of approximately 7,850 residents, with a median household income of $84,149 according to U.S. Census estimates. The project remains under the jurisdiction of local and state building codes as it moves through the pending plan review phase.
