In 1945 the Institute suffered total destruction during the liberation. As a part of the rehabilitation program, the former De Luxe Fashion School in Doroteo José was Leased Lot property for 50 years (1948-1998) and housed the high school department in 1948. In 1951, the Don Tomas B. Mapúa family acquired a piece of land from the "La Corporación Fransicana" where the present Intramuros Campus stands. The campus opened at 1956 and the building construction was completed in 1963. All college programs under deanship of Engr. Gonzalo T. Vales were transferred from the Doroteo José campus to the Intramuros Campus in 1973. Tomas B. Mapúa died on December 22, 1965 and his son Óscar Sr. took over the presidency until his death in 1998. It was under Ar. Tómas B. Mapúa, and later his son Óscar Sr., that the institute gained prominence as an engineering school. During this period, the institute took the top 10 and even the top 20 slots in most licensure exams for architecture and engineering. It also achieved the highest passing rates in the board exams among other competing schools in architecture and engineering. Tomás B. Mapúa's grandson, Ar. Oscar Mapúa Jr., took over his uties until December 1999, when the Mapúa family sold the institute to the Yuchengco Group of Companies (YGC) headed by Alfonso T. Yuchengco and appointed Reynaldo B. Vea as president. In 2002, the old RCBC Building in Sen. Gil Puyat Ave. in Makati City was purchased and converted into the Mapúa Makati Campus, where the School of Information Technology was moved from the Intramuros Campus. A spin-off of the School of IT, the Mapúa IT Center, as the Makati Campus is named, was established. The MITC offers 2-year diploma programs that eventually lead into an associate degree ladderized to the bachelor's degree (4-year) IT courses of Mapúa. Starting 2002, Mapúa, which originally was on a semestral system, adopted the quartem system. This academic system was intended to allow students to graduate faster (e.g. the original 5-year engineering programs could be taken in four years) and to focus on less, interrelated course subjects in an 11-week term. On the other hand, Mapúa High School was closed down on 2005, since it was operated in the red.
