The seat of the Imperial Council from 4 December 1883 was in the Parliament Building on Ringstraße in Vienna. Prior to the completion of this building, the House of Lords met in the Estates House of Lower Austria, and the House of Deputies met in a temporary wooden building designed by Ferdinand Fellner on Währinger Straße. The Imperial Council was dissolved on 12 November 1918, following Austria-Hungary's defeat in the First World War.
