Seattle is a city that has undergone radical urban transformations, one of which was the project of regrading the hills that run down into Puget Sound. The regrade involved lowering may existing masonry buildings as the ground was removed from beneath them. In other areas, the streets were raised so that the ground floor of entire neighborhoods became the basement. Following in the spirit of seemingly irrational urban development that fills Seattle's past, Air Space was a project which posited outcomes of radical zoning limitations and the possibility of vacating air space rights above alleyways. The proposal, although absurd, simultaneously seems to be par for the course within the historic Seattle building culture. The images were not developed as a rigorous design proposal, but as observational snapshots of an irrational future, that seems somewhat plausible when viewed through the lens of the past.
