World`s Biggest Buildings..

The Grand Egyptian Museum, Giza, Egypt

Like many new extreme forms of architecture, Giza’s planned Grand Egyptian Museum was the outcome of a competition. The $550 million museum is slated to open in 2013, despite Egypt’s political turmoil. The 210-acre project, a mile from the Giza Pyramids, will include a main structure made with translucent alabaster and a large atrium for ancient Egyptian artefacts and statues like the 3,200-year-old Ramesses II.

Abraj Al-Bait Clock Tower, Mecca, Saudi Arabia

 This mega–clock tower broke several world records when it opened in 2011. For now, it’s the tallest clock tower in the world, the tallest hotel in the world (the Fairmont Makkah Clock Royal Tower) and the world’s largest clock face — visible from 16 miles away and topped by a golden crescent minaret whose massive loudspeakers emit prayer calls to a distance of four miles

Burj Khalifa, Dubai, UAE 

The hymenocallis flower may have inspired the design team at Chicago’s Skidmore, Owings & Merrill, but the Burj Khalifa has an aggressive look, seeming to pierce the sky like a crystal weapon. The tower’s flashiest occupants are the 160-room Armani Hotel and an extra 144 Armani Residences. It may not cling to its status as world’s tallest building for long; Mecca’s Kingdom Tower is scheduled to complete construction in 2016.

 Skipark 360, Stockholm

 A lack of high mountain peaks won’t stop Swedes from skiing close to home. C F Møller began designs for an architectural ski resort powered by geothermal, solar, wind and hydropower, which when it opens in 2015 will make it the world’s biggest indoor ski resort — and the greenest. A 700m-long downhill slope and a drop of 525ft meet the requirements for hosting the World Cup.
