Burj Khalifa – Dubai, U.A.E: The year started on a literal high, as the world’s tallest skyscraper opened for business on Jan. 4, 2010. The Burj Khalifa tower, designed by Skidmore Owings & Merrill, stands at 2,717 feet, more than 160 stories high, with an Armani hotel, offices, and homes all included in the massive structure. The architecture industry has been reeling in recent years, walloped by everything from mortgage meltdowns to the deep-rooted global recession. As the financial crisis has hit home(s), construction has slowed on both residential and commercial projects, leaving architects and builders to come up with creative ways to keep their firms afloat. Here are some of the projects set to open their doors, break ground, or gain attention in 2010.
