Target Corp. will debut a redesigned store featuring a curved center aisle. On Monday, the company announced an ambitious redesign of its stores, aimed at helping people who need to dash in for essentials to get out quickly.

NEW YORK — In a move to bring shoppers back to its stores, Target is embarking on an ambitious redesign aimed at helping people who need to dash in for milk to get out quickly while encouraging those who want to wander the aisles to linger.

The new layout was unveiled by CEO Brian Cornell in Las Vegas Monday. It will feature a separate entrance and 10-minute parking for shoppers looking to pick up an online order or some essentials. New center aisles will be curved rather than squared off, to inspire people to explore, says Mark Schindele, senior vice president of Target Properties. LED track lighting will replace fluorescent fixtures, and brand boutiques meant to replicate a specialty-store feel will showcase rotating looks.

The first of the redesigned stores will open in suburban Houston this fall. About 40 more stores will get the remodel treatment by October. More than 600 of Target’s 1,800 total locations are scheduled for updates over the next three years. It expects the remodeled stores to see a 2 percent to 4 percent sales bump.

“We wanted the design to be flexible because that is what shopping is all about,” Schindele said.

The remodeling is a key part of Target Corp.’s strategy to win back shoppers and rev up sales. Unlike rival Wal-Mart, which has drawn more customers and notched higher sales at established stores, Target has seen three straight quarters of declines for that sales measure, and fewer shoppers in its stores. Investing in stores is an acknowledgment that the in-person experience remains important, even as online retailers draw shoppers away from traditional retailers.

At an investor meeting last month Target executives spoke bluntly about the shabbiness of many of the chain’s stores. It pledged to spend $7 billion on the remodeling plan and to accelerate its expansion of small-format stores, bolster its online operations, and launch new brands. “We’ve got to reimagine that store experience,” Cornell said then. “Today’s millennial shopper doesn’t enjoy shopping one of our tired stores that hasn’t been touched in 10 years.”

The Houston prototype’s separate entrances for shoppers in a hurry and those who aren’t is among its biggest novelties.

The entrance on the right will have a dedicated pickup counter for online orders.
