After Don Tomas B. Mapúa was sent to the United States in 1903-1911[1] by the Philippine-American Government to study Architecture in Cornell University, he served in the Bureau of Public Works in 1918-1927.

When the war broke out in Manila during the Japanese occupation, the Mapúa Family moved, and fortunately the mansion was spared from air raids and landmines.

After the World War II, Don Tomás and his family reacquired and reoccupied the mansion.

The mansion withstood the construction of new infrastructure adjacent to its area such as the Manila Light Rail Transit System.

To date, the mansion is undergoing restoration works by the Philippine Institute of Architects[3] and its affiliate organizations.
