The White House (Ikulu), also known in English as the State House, is the official residence and principal workplace of the President of the United Republic of Tanzania. The current building, then called Government House, was constructed under the first British Governor of Tanganyika Horace Byatt in 1922 to the designs of architect John Sinclair. It is built on the remains of the original building constructed by the German administrators of German East Africa that had been damaged by the Royal Navy in December 1914. The south wing was added in 1956 to honour the visit of Princess Margaret, Countess of Snowdon and retains the name The Princess Margaret Wing to this day. The building was renamed State House on independence.
