The Surat Diamond Bourse (SDB) is a landmark commercial edifice built in Surat, Gujarat, India, to foster the trading of rough and polished diamonds, gems and jewellery. Developed by SDB Diamond Bourse with an estimated investment of Rs34bn ($409m), the project is part of the larger Surat Diamond Research and Mercantile (DREAM) City initiative by the Gujarat government.
Spanning a floor area of 6.6 million ft² (613,160m²) and standing 81.9m (268.7ft) tall, it has surpassed the Pentagon in the US to become the world’s largest office building.
Construction of the project commenced in February 2015 and reached completion in the first half of 2022. The building was inaugurated by Indian Prime Minister Narendra Modi in December 2023.
The Surat Diamond Bourse is strategically located on 14.1 hectares (ha) of government land within the DREAM City master plan area, adjacent to Khajod village and near Dumas airport, in southern Surat.
DREAM City master plan
The DREAM City project is a burgeoning business district covering 700ha, designed to accommodate the growing needs for commercial and residential spaces in Surat. The city is known globally for diamond production, with Gujarat accounting for approximately 80% of the world’s diamond processing, primarily concentrated in Surat.
The master plan includes residential areas, commercial spaces, a golf course and a metro rail network.
The Gujarat government established the DREAM City special purpose vehicle to manage the project, with Royal HaskoningDHV Consulting and Knight & Frank India appointed as consultants in December 2015.
