The Surat Diamond Bourse, with a built-up area of 70 lakh sq. ft. is set to be the World’s Single Largest Office Building. The Surat Diamond Bourse aims to be an exemplar for integrating high-density commercial architecture along with efficient climate-responsive design. This Office building will be equipped with the state-of-the-art facilities that include safe deposit vaults, customs clearance house, convention centre, exhibition centers, training centers, entertainment areas, restaurants and a club, pushing Surat to becoming the world’s largest diamond trading hub. With an eye on providing a facilitating business environment to complement the diamond industry of the region, the Surat Diamond Bourse will be spread across 35.5 acres of land, with a total built up area of 620,000 square metres. The bourse is designed for 4,500 offices varying in sizes thereby resulting in affordable and modular spaces for all. Planned along a central axis aligned with the prevalent wind direction, the North-South oriented towers provide glare-free daylit offices accommodating functions of trading and selling of diamonds. The central spine is used for interconnection between towers on every level. The building form aims at maximising the potential of self-shading, thereby reducing dependency on other forms of cooling. The design enhances users’ spatial and transitional experience across the building without highlighting the expanse of the structure. The central axis connecting all the offices is designed as an interactive hub comprising of break-out spaces, green atriums and a host of visual experiences. These spaces have been designed to foster social cohesion and community engagement.
