Ace Hardware is doubling the size of its huge distribution center south of Dallas in Wilmer.

The Illinois-based retailer opened the shipping hub near Interstate 45 with 450,000 square feet of space in 2014.

Now Ace Hardware is adding more than 450,000 square feet of shipping and warehouse space to the complex on Pleasant Run Road in Sunridge Business Park.

"We look forward to breaking ground on the expansion of our Wilmer retail support center, an important piece in Ace's overall supply chain," Lori Bossmann, Ace's executive vice president and chief supply chain officer, said in a statement.

"Ace's continued volume growth has driven our need for a larger facility to accommodate our growing business demands. This expansion will enable faster service for Ace retailers and ultimately our valued customers."

The addition to the Ace Hardware warehouse is set to open in mid-2020.

Developer CenterPoint Properties, which built the original building, estimates that the project will create about 250 construction jobs.

Ace Hardware's Wilmer building serves about 300 Ace Hardware retail locations in Texas, New Mexico and parts of Oklahoma.

The retailer said the expansion will create about 70 more jobs.

"The city of Wilmer and the Wilmer Economic Development Corp. are excited to have Ace Hardware increase their presence in Wilmer with the 450,000-square-foot expansion of their current retail support distribution center in Sunridge Business Park," said David D. Miracle, the city's executive director of economic development.

"Ace has been a terrific corporate citizen through their support of local charities and events in Wilmer, and the city looks forward to continuing its valued relationship."

Ace Hardware is a retailer-owned hardware cooperative with more than 5,200 locally owned and operated hardware stores in approximately 70 countries.
