Some architectural companies are already preparing for the obsolescence of the parking garage. Andy Cohen, Co-CEO of Gensler, one of the world’s leading architectural firms, says parking structures that are traditionally built with slanted floors. His firm is already dealing with adapting parking requirements for a future of self-driving cars. Today, they are starting to build garages with horizontal floors and an exterior, rather than interior ramp, so the structures can be more easily converted from a parking deck to a traditional office space.
