A developer has registered plans with the state for four new warehouse buildings at 621 W. Prosper Trail, with construction penciled in to begin next week.
The project, called Prosper Flex Park, shows up in the Texas Department of Licensing and Regulation's accessibility database as four separate filings entered Sept. 15 and 16, one for each building. Each describes ground-up construction of a 38,500-square-foot industrial distribution warehouse.
Together, the buildings add up to about 154,000 square feet. Each carries an estimated cost of $3,464,878, for a combined total of roughly $13.86 million.
Timeline
All four filings list the same schedule: a start date of Oct. 15, 2026, and completion by July 15, 2027. Those dates come from the developer's registration and are estimates that can shift.
The owner of record is Prosper Trail Commercial LP, with a Dallas address on North Central Expressway. Dallas firm GSR Andrade Architects is listed as the designer. The filings say the project is privately funded, and none of them names a tenant, so it is not yet known which businesses will occupy the space.
