11 Diagonal Street (also known as the diamond building[2]) is an iconic office tower in downtown Johannesburg, South Africa, that was built by Anglo American Property Services.[3] The 22 floor building is the 15th tallest in the city[4] and it was conceptualized in 1981 and excavations began in December that year. Construction ended in 1983 and the building was tenanted in 1984.[5] The building is designed to look like a diamond as it reflects different views of the Central Business District from each angle of the building.[6] Apart from its unique exterior, the structure was built with concrete instead of steel, demonstrating that concrete could be used instead of steel in both speed and cost.[7]

The building's architect was Helmut Jahn.[8]

Current Use

The building was used by the department of Development Planning & Local Government.[9] It is currently occupied by The Gauteng Department of Infrastructure Development.[10]
