Coherent - Zone 1 Diamond Growth

Coherent is renovating 12,500 square feet of existing storage space into a production area at 16479 N. Dallas Parkway, Suite 400, in Addison. The project, filed with TDLR as Coherent - Zone 1 Diamond Growth, involves converting the support level of an existing building to serve production needs. Existing building utilities will support the renovated space, eliminating the need for new utility infrastructure. The estimated cost for this renovation and alteration is $3,500,000.

The work is scheduled to have begun in August 2024, with a completion date listed on the filing as March 2025. MJDII Architects, Inc. is the design firm of record for this project. The project is privately funded on private land for private use. TDLR completed plan review in June 2024 and construction was scheduled to finish in March 2025; TDLR has not yet recorded a final inspection, so the current state of the site is not confirmed in the public record.
