Architect Leroy L. Warner introduced a new concept in 1950: “Park at Your Desk.” The center of the Cafritz office building in Washington, D.C., was a multi-story parking garage with a helical ramp, and set around this core was a ring of shallow day-lit offices. So each worker could drive into the building, drive up to their floor, park their car, and then walk just a few meters to the office.

Why didn’t this catch on? Architect Philip Steadman points out that the design constraints allowed for 150 people per floor but only 29 parking spaces, a bad mismatch. (Also, “One wonders about air quality in the offices.”)
