A few more generic renderings taken from the website...
This rendering shows where the High Line meets the High Line spur, as well as the Cultural building that will be a part of the site (left, more on that later).
The large base would be the first tower.
Looking east on 33rd over the plaza and the Time Warner Center-like office and retail development.
Subway station (minus the former World Product Center proposal)
The office towers that form the eastern border will sit atop 5 levels of retail...
A hotel will also be on site, just south of Extell's former WPC site...
And a generic view of the development...
