Las Colinas continues to be the biggest in the Dallas-Fort Worth area when it comes to our list of the Largest North Texas Office Parks with 24,299,622 completed square feet. Leanne Weymouth of the Irving Economic Development Partnership, who along with John Bonnot is the leasing agent for the area, foresees Las Colinas as continuing to find ways to grow. Even though there are 200 completed buildings and close to 7,500 tenant companies, additional planned square footage is set at 500,000 square feet for the area that covers roughly 12,000 acres in Irving. Special services that are provided in Las Colinas include lakes, canals, jogging and biking trails, golf courses and convention center hotels. Legacy is a distant second on the list with 15.5 million square feet of completed space, followed by CentrePort Business Park at 14.9 million, AllianceTexas at 3,753,465 square feet and Galatyn Park with 3,739,550 square feet of completed space.
