Build a mega box . . . then stack four big boxes across the top.
Big-box retail, a suburban setting, and a tight site demanded an innovative precast concept for The District at Howell Mill project. The solution? Establish Walmart with a huge presence at grade level, close to well-lit parking decks and stack big-box retail on top, served by wide streets and pedestrian friendly access.
