The Colony's first Costco Wholesale swung open its doors on Friday, October 16, bringing a 155,000-square-foot warehouse and a members-only fueling station to the Grandscape development near the Plano border. The new store, located at 6060 Grandscape Blvd., joins a wave of outer-suburb Costco openings reshaping shopping habits across North Texas.
According to Community Impact, the warehouse stocks brand-name and private-label merchandise including groceries, candy, electronics, hardware, apparel and jewelry, with prices positioned below typical retail stores according to a company news release. The outlet notes Costco operates nearly 1,000 warehouses worldwide and already has a strong Dallas-Fort Worth presence, with two Plano locations and one in Frisco, plus a Prosper store that opened in March 2025.
The Costco's gas station is located at the corner of Spring Creek Parkway and Grandscape Boulevard.
How The Colony Landed Its Costco
The path to the warehouse's opening ran through The Colony's City Council, which approved the site plan for the 155,000-square-foot store and its gas station in September 2025, according to Citizen Portal. The 32-acre parcel falls within Planned Development 25, and the approval followed a unanimous 6-0 recommendation from the Planning & Zoning Commission.
The Colony launch fits into a broader wave of Costco expansion in North Texas, as Local Profile describes. The retailer opened a 158,000-square-foot store in Celina on August 26, 2026, and has filed for a Wylie location estimated at more than $42 million. Per the same report, the new warehouse expands Costco's footprint along the State Highway 121 corridor.
Grandscape's Berkshire Hathaway Backing
The Costco sits inside Grandscape, a 433-acre mixed-use development along the Highway 121 corridor.
Residential development near Grandscape is also continuing, with apartment developer JPI breaking ground this spring on Jefferson Grandscape II, a $77.8 million, 277-unit complex along Nebraska Furniture Mart Drive slated for completion in January 2028, according to WFAA.
