Sir Norman Foster, one of the leading architects of our times, currently launches a project of world’s largest building. The building will be built in Moscow, The Sunday Times reports.

The skyscraper, dubbed as the Crystal Island, is 449.88 meters high. When completed, the building will look like a spiraling pyramid. The foot of the pyramid will be 701 meters in diameter.

The Crystal Island has already earned the reputation of the most ambitious building project in the world. The construction is evaluated at four billion dollars.

The city within the building will house 900 luxury apartments, 3,000 hotel rooms, a theater, a fitness complex, a cinema, a museum and an international school for 500 students, not to mention countless stores.

The Crystal Island will be Lord Foster’s second large-scale project in Moscow, and his third building design that resembles a volcano. Many people call the new building the Christmas tree of Moscow. However, the project may put Russia at the forefront of a new wave of city design. The Crystal Island will also symbolize Russia’s powerful economic rise.

Most likely, the skyscraper will be built about ten kilometers far from Moscow’s center. The project is set to be completed in 2014.

The exterior facade will be solar responsive and will include solar panels. The panels, along with turbines, will generate electricity for the huge building.
