Erich Mendelsohn designe the Weizmann House in 1937. This was the home of the first Israel President, Chaim Weizmann, and after his death it became the official house of the Presidents of Israel. The design concept behind the home was to keep an international style to accommodate the variety different of cultures that visit the home. The structure is centered around a cylindrical stairwell and a pool in the center, and it also focuses on using the landscape around the home (11 acres).
