I find myself revisiting a concept called revealing verticality in which spaces existing in the Z direction alters perceptions of scale and volume.

So I was speculating on the future of the city and I said, well, obviously, compared to present and future cities, New York is not going to be able to compete in terms of size anymore. It used to be a large city, but now it’s a small city compared with São Paulo, Mexico City, Kuala Lumpur, or almost any Asian city of any size. So I said maybe New York can establish a new kind of scale – and the scale I was interested in was the scale of the city to the Earth, to the planet. I made the drawing as a demonstration of the fact that Manhattan exists, with its towers and skyscrapers, because it sits on a rock – on a granite base. You can put all this weight in a very small area because Manhattan sits on the Earth. Let’s not forget that buildings sit on the Earth.

I wanted to suggest that maybe lower Manhattan – not lower downtown, but lower in the sense of below the city– could form a new relationship with the planet. So, in the drawing, you see that the East River and the Hudson are both dammed. They’re purposefully drained, as it were. The underground – or lower Manhattan – is revealed, and, in the drawing, there are suggestions of inhabitation in that lower region.

So it was a romantic idea – and the drawing is very conceptual in that sense.
