On the day of the reopening, President Chen made a speech announcing a plan to expand the museum, solving the space limitations it was facing. This plan was formulated by the Council for Cultural Affairs, and will see the museum's premises extended into the former premises of the Land Bank across the road.
為了解決展出空間侷促的問題，陳水扁總統在開館日蒞會致詞時，特別指示文建會規劃台博館擴建計畫，也就是串聯對街已遷離閒置的土地銀行舊址，朝地下層擴展。
