New Walmart headquarters to bring in natural light

Walmart plans to do away with the "inefficient" current campus of its corporate headquarters — a sprawling collection of more than 20 buildings in Bentonville, Ark. — and replace it with new facilities that will encourage a more efficient business.

The buildings are "expensive and inefficient to maintain, costing millions of dollars of accelerating upkeep every year," wrote CEO Doug McMillon in a company blog post.

The new headquarters, integrated into the city's trail system, will encourage employees to walk or bike to work. Employees will also see "improved parking, meal services, fitness, and natural light — yes, natural light," he wrote.

Walmart has been acquiring land in the area and expects the new campus to take as many as seven years to complete.
