North of Dallas in the suburb of Plano there has been an explosion of corporate development known as Legacy. Mid-rise office buildings and company headquarters relocation has led to massive construction projects. Toyota's $350 million US headquarters project is not an exception. The buildings are designed by Dallas-based firm Corgan and the grounds are designed by the Office of James Burnett, the same mastermind behind the highly-lauded Klyde Warren Park in downtown Dallas.
