Narut have a look.

I found this project that resembles your skyscraper project but is also interesting in the sense that.... landscape is many times made from the leftover/residue spaces from architecture... but here landscape becomes the core program and that the infrastructure then becomes the support of it... its just this shift of roles that I find interesting.
