The title of the world's largest office has been taken off of Pentagon after 80 years by a building in Surat that will be home to a diamond trading centre. Ninety percent of the world's diamonds are cut in Surat, which is referred to be the gem capital of the world. Over 65,000 diamond professionals, including cutters, polishers, and merchants, will use the newly built Surat Diamond Bourse as a "one-stop destination."

According to a CNN source, the 15-story tower features nine rectangular buildings and is situated on 35 acres of ground. They are all connected through a spine in the middle. The business that constructed the enormous facility claims that it has a floor area of more than 7.1 million square feet. Prime Minister Narendra Modi will formally dedicate the structure in November. The building was built over the course of four years.

The property contains a 20 lakh square foot parking area and recreational zone, according to the SDB website. It is a non-profit organization supported by SDB Diamond Bourse, a business established for the establishment and promotion of Diamond Bourse in Surat, Gujarat, and registered under section 8 of the Companies Act of 2013. Mahesh Gadhavi, the project's CEO, told CNN that the new building complex will prevent thousands of individuals from going by train to Mumbai frequently to conduct business.

The CNN report showcased numerous luxurious features, including marble floors and sunlit atriums that connect more than 4,700 office spaces. These spaces can also serve as compact workshops for diamond cutting and polishing. The development, valued at 32 billion rupees ($388 million), boasts 131 elevators and offers a range of amenities such as dining, retail, wellness, and conference facilities.

Following a global design competition, the building was created by the Indian architectural firm Morphogenesis. "Surpassing the Pentagon was not part of the competition brief. Rather, the project's size was dictated by demand," said Mr Gadhavi.
