Three new WTC Towers were announced yesterday to compliment the Freedom Tower. From BBC News:
“The tallest of the skyscrapers, and the last to be built, will be topped by four diamonds that will point towards the memorial park from any vantage point in the city, architects say.
Designed by Lord Foster, the diamonds will light up lower Manhattan at night.
Lord Rogers’s building will be more slender and designs show it featuring four 100ft (30m) spires – one at each corner.
Fumihiko Maki’s minimalist fourth tower will be covered in perforated aluminium, making it the lightest of the skyscrapers, according to its designer.
The landmark buildings are intended to complement Freedom Tower – which at 1,776ft (541m) is set to become the tallest building in the United States.
All building work on the site is due to be completed by 2012.”
Detailed information about the towers can be found on the Lower Manhattan Development Corporation site.
