Executive Summary
The Foundry | Plano introduces a new category within North Texas office: a curated collection of individually owned luxury headquarters buildings designed for founder-led companies, professional firms, advisors, auto enthusiasts, creators, and emerging brands seeking ownership rather than leasing.
Located within Mustang Square along Highway 121 in the highly desirable Plano-Frisco corridor, The Foundry offers businesses the opportunity to establish a permanent workstead presence in one of the nation's most dynamic concentrations of wealth, corporate growth, and professional talent. Immediate access to Legacy West, The Star, Grandscape, Stonebriar, and major regional corporate campuses places owners at the center of North Texas enterprise growth.
Unlike traditional office developments, The Foundry consists of a limited collection of standalone office-condo buildings ranging from approximately 3,500 to 3,840 square feet. Each building is thoughtfully designed across two levels, creating a natural separation between client-facing environments, team operations, executive leadership, and strategic planning spaces.
