This Indian Building Surpasses Pentagon To Become World's Largest Office

The building will be officially inaugurated by Prime Minister Narendra Modi in November this year. It took four years to complete its construction.

For 80 years, Pentagon was the world's largest office building. But that title has now been taken by a building in Gujarat's Surat that will house a diamond trading centre, according to a CNN report. Surat is known as the gem capital of the world where 90 per cent of the world's diamonds are cut. The newly-constructed Surat Diamond Bourse will be a "one-stop destination" for over 65,000 diamond professionals, including cutters, polishers and traders, the outlet further said.

The 15-storey building is spread across 35 acres of land and has nine rectangular structures, as per the CNN report. They are all interconnected via a central spine.
