11 Diagonal Street, High-rise building in Central Business District, Johannesburg, South Africa.
The 20-story glass structure stands 80 meters tall and features a geometric facade that mirrors different views of the surrounding cityscape from each angle.
German architect Helmut Jahn designed this commercial building, which began construction in 1983 and opened its doors to businesses in 1984.
The building's angular glass exterior draws inspiration from South Africa's diamond mining heritage, incorporating this element into modern architectural design.
Six elevators serve the building's 20 floors, providing access to approximately 20,000 square meters of office space in the business district.
Each face of the building's glass exterior creates different reflections throughout the day, altering the appearance of the structure as sunlight moves across its surface.
