Surat Diamond Bourse: World's largest office building that overtook Pentagon

The title of the world's largest office building, which was held by the Pentagon for 80 years, will soon be taken over by a building in Gujarat's Surat, according to a CNN report.

The newly-constructed Surat Diamond Bourse will be a one-stop destination for over 65,000 diamond professionals, including cutters, polishers and traders.

The 15-storey building is spread across 35 acres of land and has nine rectangular structures. They are all interconnected via a central spine. It comprises over 7.1 million square feet of floor space. The complex has a recreational zone and parking area spread across 20 lakh square foot.

The building has been designed by Indian architecture firm Morphogenesis, based in New Delhi. The project took about a period of four years to complete. As per CNN, the projects costs about 32 billion rupees.

It aims to save thousands of people from the hassle of daily travel to Mumbai for business purposes.

The building will be officially opened later this year by Prime Minister Narendra Modi, and host its first occupants in November, as per the report.
