Architect-engineer Santiago Calatrava has unveiled plans for a tower of "townhouses in the sky" for lower Manhattan, immediately adjacent to the Brooklyn Bridge -- itself a pretty inspiring piece of work.
Interestingly, the crystalline "townhouses in the sky" barely picks up on their neighbour, the Bridge, at all, whereas Calatrava's project for a new rail terminal at the World Trade Centre site (below) does almost explicitly, and beautifully.
(You can see a QuickTime video of this Twenty-First Century Grand Central at Calatrava's own site. Look for the WTC PATH Terminal, and click on the 'Video' link.)
