Target Corp. has unveiled design elements of a major store makeover, including an enhanced grocery department design that will feature a wider assortment of fresh produce as well as quick grab-and-go options and meal solutions.

The retail chain has committed to investing billions of dollars over the next three years to reimagine hundreds of existing stores. The first fully reimagined store is expected to open in October in the Houston suburb of Richmond near Grand Parkway Southwest.

“With our next generation of store design, we’re investing to take the Target shopping experience to the next level by offering more elevated product presentations and a number of time-saving features,” said Brian Cornell, chairman and chief executive officer. “The new design for this Houston store will provide the vision for the 500 reimagined stores planned for 2018 and 2019, with the goal of taking a customized approach to creating an enhanced shopping experience.”

In addition to the Houston location, 40 stores will receive elements of Target’s next generation re-design when they are updated in October 2017. Target said it will use guest feedback as it moves forward on plans for the 500 stores being reimagined in 2018 and 2019.

In addition to the enhanced grocery department design, Target said the new design will offer two entrances, each with a specific guest need in mind. Guests may enter through one entrance to find displays of exclusive brands and seasonal offerings, or a second entrance for pick-up of on-line orders and groceries.

Target’s investment to reimagine 600 stores by 2019 is part of the company’s strategy to create a “smart network,” with stores, digital channels and supply chain working together to meet guests’ needs. The company’s announcement follows Target’s previously shared plans to open more than 100 small-format stores over the next three years.
