Occasionally, a big name architect will produce an interesting looking parking garage, but such efforts are not typical. Car parks occupy marginal space in buildings, which is a slight improvement over the outside parking lot which tends to dominate a building site. The LED revolution will at least make the interior experience more bearable, and maybe even safer.
Self-driving cars, Uber, and expanded public transportation will not result in the abandonment of parking garages. In fact, we can expect even larger and more sophisticated structures in the near future. Forward the foundation.
