Description

The Foundry | Plano introduces a new category of office ownership in North Texas: a limited collection of individually owned, standalone headquarters buildings designed for businesses seeking a permanent home rather than leased space.

Located within Mustang Square at the intersection of State Highway 121 and Razor Boulevard in the highly desirable Plano–Frisco corridor, The Foundry places owners at the center of one of the nation's most dynamic concentrations of wealth, corporate investment, and professional talent. Legacy West, The Star, Grandscape, Stonebriar Centre, Toyota, Samsung, AT&T, and many of North Texas' premier employers and destinations are all just minutes away—creating an address designed for long-term business growth and asset appreciation.

The campus consists of twelve standalone, two-story office buildings ranging from approximately 3,500 to 3,840 square feet. Every building is delivered as The Foundry Standard—a fully finished, premium-ready office designed to accommodate a wide range of businesses from day one. Following execution of the Purchase and Sale Agreement, owners may choose to build the standard plan exactly as designed or begin a collaborative architectural, engineering, and design process to tailor the building around their specific business, operational needs, and long-term vision.

The result is a building that functions as more than office space—it becomes a permanent business asset, thoughtfully designed around the company it serves.
