Chancellor House is a law office building situated at 25 Fox Street, Ferreirasdorp, Johannesburg, that once housed the Mandela and Tambo law firm of Nelson Mandela and Oliver Tambo. It is a national heritage site. The building was due to be bought by the Johannesburg Heritage Trust in 2004 and developed into a tourist destination, with R300 000 earmarked for the construction of a visitor center. As of 2008, however, no purchase had been consummated and the building reportedly continued to fall into ruin. Full restoration of the building was completed in May, 2011.
