McKinney Flex Park is a planned 6.2-acre mixed-use development at 1990 N McDonald St — roughly 75,000 SF across 40+ units from 1,800 to 3,500 SF, including about 20,000 SF of retail and showroom frontage. It is built for businesses that need operations space and customer visibility at the same address.
Most small-bay parks are operations-only: you get a warehouse bay and a door, and customers never visit. McKinney is planned differently.
Roughly 20,000 SF of the build fronts McDonald Street as retail and showroom space, with flex bays behind and beside it. That matters if your business has two halves. A flooring company can put samples and a design desk in the front while cutting and staging in the back. A specialty retailer can sell from the storefront and hold inventory twenty feet away instead of paying for offsite storage. A service business can meet clients somewhere that looks like a real business.
Collin County has been among the fastest-growing counties in the country for a decade, and McKinney sits at the center of it. Rooftops arrive ahead of the commercial space that serves them, which is exactly the gap small-bay flex fills — the contractors, trades, and local businesses that support new housing need somewhere to operate from.
The site fronts N McDonald Street (State Highway 5), a primary north-south corridor through McKinney, north of the historic downtown square and inside the city's growth path rather than behind it.
The park is in design and permitting now. Registering interest before construction means you can influence unit sizing and configuration for your operation rather than adapting to a finished shell.
Because McKinney pairs storefront frontage with working bays, the tenant mix runs wider than a pure industrial park. These are the businesses it is built for.
Not sure your use is allowed? Can you run a gym, church, or retail in flex space? covers what to check before you sign.
We build both, so here is the honest comparison rather than a pitch for whichever is closer to you.
If you need space sooner and your customers rarely visit, Rockwall is the faster path. If foot traffic and storefront visibility drive your revenue, McKinney is worth the wait.

Mixed-use: roughly 75,000 SF across 40+ units combining retail, showroom, and flex industrial space, with about 20,000 SF of retail and showroom fronting McDonald Street. Unit sizes run 1,800 to 3,500 SF.
Groundbreaking is planned for Q4 2026, with delivery expected in late 2027. The site is secured and currently in design and permitting. Early interest registrations get first look at unit selection.
Yes. Unlike a purely industrial park, McKinney is designed with retail and showroom frontage on McDonald Street specifically for customer-facing businesses, with flex bays for operations behind them. Confirm your specific use — our guide to permitted use explains what to check.
Rockwall is a pure small-bay flex park of 30 units from 1,500 to 3,000 SF delivering Summer 2027. McKinney is larger and mixed-use with retail frontage, breaking ground Q4 2026. Choose Rockwall for operations-first, McKinney if customer traffic matters.
We build and operate these buildings, so we would rather you lease the right space than the nearest one.
