The Wait Is Almost Over
For years, the absence of a Costco in this part of Denton County has been one of those low-grade civic grievances that comes up at dinner tables and neighborhood Facebook groups with reliable frequency. Residents of The Colony and the surrounding communities have made the trek to Frisco, Plano, or beyond, membership card in hand, to stock up on bulk olive oil and oversized muffins. That drive is getting shorter.
Costco is officially under construction at Grandscape, positioned along Sam Rayburn Tollway at West Spring Creek Road. The projected opening is fall 2026 — which, given where the calendar sits right now, means the city could be cutting a ribbon before the year is out.
What This Means for Grandscape
Grandscape has spent the last several years building itself into something that defies easy categorization. It is not quite a traditional mall, not quite an outdoor lifestyle center, and not quite an entertainment district — it is all three at once, and the Costco addition shifts the development’s center of gravity in an interesting direction.
Most of Grandscape’s marquee tenants lean toward experience: places you go to spend an evening, hear live music, eat something interesting, or play a round of soccer-themed games. Costco is different. It is a weekly errand destination for the households that hold a membership, which means the Sam Rayburn Tollway corridor is about to draw a new category of regular traffic — not just people looking for a night out, but people who need paper towels and rotisserie chicken on a Tuesday afternoon.
That kind of anchor tenant changes the math for every other business in the development. Foot traffic that arrives for a Costco run does not always leave immediately, and the businesses surrounding the new location stand to benefit from that spillover in ways that are difficult to manufacture through marketing alone.
Part of a Larger Buildout
The Costco construction does not exist in isolation. Grandscape is in the middle of a notable expansion period. White Castle has already broken ground on its first Texas location within the development, a 3,430-square-foot restaurant with a double drive-thru and patio seating, with a grand opening expected in late fall 2026. That project alone is expected to bring 70 jobs to the local area. TOCA Social, the soccer-inspired entertainment venue founded by U.S. World Cup veteran Eddy Lewis, is already open and operating as the U.S. flagship. The Rustic, the well-known Dallas bar and music venue, took over the former Lava Cantina space this summer and has been drawing crowds with its nightly local musician lineups and wood-grilled menu.
Taken together, these additions represent a significant chapter in Grandscape’s ongoing development. The Costco fits within that story not as an outlier but as a practical counterweight — a tenant that serves the everyday needs of the same households that are already driving to Grandscape for dinner and entertainment.
The Sam Rayburn Tollway Corridor
The specific location matters. The intersection of Sam Rayburn Tollway and West Spring Creek Road sits at a point that pulls from multiple directions — The Colony residents to the north and east, Frisco residents to the south and west, and the steady flow of commuter traffic that uses SH 121 as a primary corridor. A Costco at that intersection is not just a convenience for The Colony; it is a regional draw that places the city at the center of a much larger trade area.
That positioning has long been part of The Colony’s economic development strategy, and Grandscape has been the primary vehicle for executing it. The development’s scale — the sheer amount of square footage and the diversity of tenants — gives it the kind of gravitational pull that smaller retail corridors cannot replicate. Adding a Costco to that mix reinforces the argument that Grandscape is not finished becoming what it is going to be.
What to Watch For
No specific grand opening date has been confirmed beyond the fall 2026 window. Residents who want to track the timeline should keep an eye on the Sam Rayburn Tollway construction site itself, which is visible from the tollway, as well as official announcements from the city and Grandscape. The Colony’s city website at thecolonytx.gov has been a consistent source for development updates, and Visit The Colony has covered the Grandscape expansion as it has progressed.
In the meantime, the construction activity visible along West Spring Creek Road is doing something that no press release fully accomplishes — it is making the arrival feel real to the people who drive past it every day. For a community that has watched Grandscape grow from an ambitious concept into a functioning destination, the sight of another major tenant taking shape is a familiar kind of confirmation that the development’s momentum has not slowed.
