The first floor included the room of Ben-Gurion's second daughter, Renana. It also served Ben-Gurion during the Suez Crisis (Mivtza' Kadesh, "Operation Kadesh") as a shelter and a bedroom. From this room Ben-Gurion conducted his communication with Moshe Dayan, then his Chief of Staff, and from there he received front line updates on the progress of the operation.[4]
