The ambitious architects at Foster + Partners have announced another huge project, in fact this might be the huge project. They have unveiled renderings for Crystal Island, a £2 billion "city inside a building" in Moscow which will be the world's biggest building. Now note, I didn't say tallest, although it is tall. This one is all about the sprawl, it will be have four times the floor space of the Pentagon building in Washington D.C., more floor space than any other structure on Earth. The building will stretch almost 1,500 feet into the sky and will be a multi-use structure. The building will include 900 apartments, 3,000 hotel rooms, a school for 500 students, a movie theater, a museum, a sports complex and dozens of shops. Some critics say it resembles a giant Christmas tree (the tower does spread downward from the top peak, and will be a vulgar blight) on the Moscow cityscape. The structure will be placed on a peninsula located five miles from the city center and it is expected to be completed in six years.
