The Satyagraha House, commonly known as Gandhi House, is a museum and guest house that belonged to Mahatma Gandhi: he lived and worked there between 1908 and 1909. It is registered as part of Johannesburg's historical heritage.
The house was designed by the architect and close friend Hermann Kallenbach for Gandhi and himself. Gandhi slept in an attic room which he entered via a ladder, but he and Kallenbach shared the same kitchen and entertained their guests in the living room. The houses did not have connecting doors and it was necessary to leave one house in order to enter the other. Kallenbach's life was transformed by their life together and the money that he spent on himself was cut to a tenth of its initial figure.

Within these walls, Mahatma created and developed his philosophy of passive resistance: Satyagraha in Sanskrit. A pacifist method of protest that he employed in India to lead the country to independence.
