Walmart Inc. has unveiled its plans for its new high-tech headquarters complex in Bentonville, Ark., which it expects will help it lure talent and accelerate its digital transformation.

Walmart plans to open the new headquarters gradually between 2020 and 2024, the retailer said in a May 17 blog post on its website.

Walmart expects to start demolition, infrastructure and utility construction in summer 2019, while designing and construction of support and office buildings is expected to start in the next 18 to 24 months. The retailer did not disclose the cost of the headquarters in the May 17 blog post. The retailer said the complex will include solar panels, energy-efficient lighting systems and mass timber construction.

Walmart said its new headquarters, which it first announced in September 2017, will have a variety of food options, parking spaces, fitness facilities and a child care facility.
