In fact, the best thing about the design isn't the lavish exercise facilities, but the way the Kroc Center has been arranged on the site by MGA and the Manayunk landscape architects at Andropogon. The new building bookends a gutted, but classically muscular, factory loft where Budd sold automotive parts. At the far end, the site is bounded by another industrial-era staple, a long, sawtooth workshop, completing a cozy U-shaped block. SEPTA trains run through the site, alongside the playing fields, and they infuse the ensemble with the promise of urban energy.
