Crews staged a topping out ceremony Monday for Four World Trade Center, the first of the buildings under construction on the site to reach the milestone. The ceremony centered on a beam signed by members of the construction crew, which was hoisted 977 feet to the top the building.

The design of the 64-story glass and steel office tower is intended as an architectural backdrop to the September 11th memorial, according to the building's developer, Silverstein Properties.
The architects, Pritzker Prize-winning Maki and Associates of Tokyo, designed the tower to be "understated and deferential," the New York Times reports. The trapezoidal building nearly disappears at some angles and, at specific times of day, acts as a mirror reflecting the sky.
“We like the idea of the building dematerializing,” Osamu Sassa, the project architect for the firm, told the Times. "Subtlety extends one’s appreciation."
Four World Trade is slated to open in 2013. About 60 percent the building has been leased to the city and Port Authority, according to Crain's.
