I sent some comment/ideas/images to the consultants working on the "Philly District 30" Plan a while ago which included some building massings exactly where they have placed a few of these buildings, but they are way more ambitious than I would have dreamed.
I thought my 650' building would be scoffed at, who'd have thought I was being way to conservative!
Anyway, the rest of my sketches
are here if you are interested (It mostly pertains to designs on capping the rail yard for development, and expanding the 30th St Station) I guess Ill have to update my designs with the new proposed buildings,
