It was built in 1920 after the fashion of the Presidential Building in Taipei in terms of style and materials. The museum was owned by Ku Wei-fu and later donated by the Ku brothers as a public attraction. It occupies an area of 1,900 pings (68,400 square feet). Even by modern standards it still commands an air of greatness and dignity.
這棟大宅，佔地一千三百多坪，建成於民國九年，其建築師與建材都和台北市總統府相同，房宅內外與前後庭院，以現代眼光看來，仍覺堂皇富麗、氣派非凡。
