Owing to the increase in students this century, the school finally brought in architects to redesign the campus. But because the land is uneven and has its back to the bay, the school sprawled into a mix of closely packed buildings of all kinds of architectural styles.
本世紀因為學生增加，校方才請建築師設計、規畫校園設施，但由於面山背海的柏克萊佔地不大，地形又凹凸不平，系所不斷擴張，一直往四周加蓋，使柏克萊形成許多建築風格各異、卻緊鄰的小區域。
