Originally the offices of the Johannesburg Bar, Innes Chambers was purchased by the Department of Public Works for redevelopment as the Johannesburg offices of the National Prosecuting Authority.

Designed in 1960, Innes Chambers is a downtown landmark and a model example of 1960’s modernist architecture. Every effort was made to retain and restore original façade heritage elements.

The building’s original architect - Abramowich described the process of designing the distinctive Y-column facade screens; “the screens were created not only as an aesthetic element, but also as a shading device, to keep the building cool in summer, and reduce reliance on mechanical air-conditioning,” sketched under a tree in his garden on a Friday afternoon in 1959.
