Parking decks often are not much to look at or ponder, but architect Shannon McDonald has written a book that explores their history and calls for their continued evolution as important modern-day structures. “The Parking Garage: Design and Evolution of a Modern Urban Form,” includes hundreds of photographs that demonstrate how well-designed parking positively affects the urban environment. She chronicles the evolution and innovations from early elevator and ramp designs through modern, sustainable structures being built today.
