The past years have been witness to the tremendous development in the University’s Physical Plant. The year 1965 saw the construction of a one-storey, four-room High School Building which was named as the Hantson Building. In 1968, what used to be the former San Jacinto Seminary was turned over to the College, which later became the Administration Building. In 1972, the old Ateneo High School building was renovated, and the Jesuit Fathers’ quarters were converted into High School Library and Laboratories. In 1975, a four-room building was constructed as annex to the old High School building. In 1977, with the financial assistance of the Dutch Government, the CEBEMO, two buildings were constructed: Bishop Constant Jurgens Technical Building and the CEBEMO Shop Building. The year 1978 saw the construction of the CICM District House for the CICM Fathers. In 1979, a new two-storey, eight-room concrete building (Phase I) was constructed in the High School Department. Likewise, the Saint Aloysius Building was built in 1979.
In 1980, the College gymnasium was completed. In order to meet the tremendous increase in the enrolment of the College, in 1981, the old Hantson Building was demolished and on its site was a two-storey, eight-room building, later named as San Lorenzo Ruiz Building. In 1982, a new three-storey building was erected to house major administrative offices and more classrooms. This building was named the CICM Building in celebration of the 75th (Diamond) Jubilee of the CICM Missionaries in the Philippines. The year 1984 saw the completion of the Mary Immaculate Ladies Dormitory, and in 1988, the USL stadium.
In 1999, the Bishop Constant Jurgens Technical building was renovated and expanded to a three-storey concrete building right at the center of the campus. This building was renamed as Fr. Theophiel Verbist, the founder of the CICM Congregation. This building housed the Treasury and Accounting Department, the Office of the Registrar, the Office of the Chaplain, the canteen, a bookstore, printing shop, and function room on the ground and mezzanine floors. The higher floors were supporting twenty lecture rooms and computer laboratories.
The year 2000 saw the acquisition of a 5.4-hectare lot in the hills of Leonarda, Tuguegarao City to become an extension site for the fast growing Louisian family.
The school year 2000-2001 was marked by the construction of the main High School building (Phase 3) which since then on has been housing the administrative offices for the High School Department and several classrooms. The three major buildings of the High School Department are linked together to form the so-called Charles Pieters Building.
In the summer of 2001, major movements in the facilities were undertaken. The three higher floors of the Theophiel Verbist building took a major renovation to accommodate the new, modern and fully air-conditioned Learning Resource Center (Library) of the College Department. That summer, too, preparation for the construction of the Bishop Constant Jurgens building started as the old Bishop Constant Jurgens Technical Building was renovated and renamed Theophiel Verbist Building in 1999. The Bishop Constant Jurgens building later became the Prep/Grade School Building.
With the offering of new curricular programs, buildings were put up at the Extension campus along Lecaros Street which is adjacent to the main campus. First was the Pope John Paul II Building, erected in 2004, to cater to the needs of the University’s Nursing program. It houses the Nursing laboratories, Dean’s Office and classrooms. Second was the Tjolle International Center in 2005 which serves as the hotel laboratory for the Hotel and Restaurant Management program.
To expand the Leonarda expansion site, the University purchased in 2008 an additional lot with an area of 4.6 hectares adjoining the 5.4 hectares purchased in year 2000, thus the 10-hectare area of the entire Leonarda Expansion Campus.
In the year 2011, a new High School audio-visual room with a 150 seating- capacity was added to the structure of the Charles Pieters Building. It was named Bulwagang Pacifico Casem in honor of Mr. Pacifico Casem, a former High School principal who also became a president of the then Saint Louis College of Tuguegarao. The Bulwagang Teodulfo Domingo (in honor of former Bishop of the Diocese of Tuguegarao, Msgr. Teodulfo Domingo) was earlier built as part of the Charles Pieters Building, and is used for seminars, conferences, and other related events.
The M Building was put up in 2012 to house the laboratories of the Pharmacy and Medical Laboratory Science (Medical Technology) programs, additional laboratories for the Hotel and Restaurant Management program, faculty rooms, and another dean’s office. It is named Immaculate Heart of Mary Building.
With the continuing need for classrooms, better faculty rooms, and audio-visual rooms, the N Building was blessed and inaugurated in summer 2014. It houses the new college faculty rooms and function halls. It is also equipped with simulation rooms which are envisioned to become centers for innovation in the University.
In year 2014, two other buildings were constructed, O Building and P Building, to address the increasing number of enrolment of the High School department as well as to meet the Technology and Livelihood Education (TLE) laboratories required by the K-12 Enhanced Basic Education Curriculum. In the same year, the Q Building was constructed and now houses the Student Affairs Office (SAO) and the Supreme Student Council and The Louisian Courier offices.
In school year 2014-2015, the University acquired the USL Main Campus lot from the Archdiocese of Tuguegarao, USL now having full ownership of the 4.2-hectare lot. Signing of the deed of absolute sale and full payment of the lot were done on November 17, 2014.
To house the Senior High School, an academic building was constructed in time for its opening for SY 2016-2017 in August 2016. At the site where it now stands was once the Mary Immaculate Ladies Dormitory, which was demolished. It is named Clement Daelman Building.
In SY 2016-2017, the N Extension Building, a replicate building of the N Building, was constructed. It stands on the location of the demolished San Lorenzo Building. It houses college classrooms, facilities, and administrative offices. The entire N Building has been renamed as Saint Lorenzo Ruiz Building.
As USL bursts forth as a global university, it envisions future expansion in both facilities and space; thus, the Leonarda Campus Development Plan, to be realized at the University’s property at Leonarda, Tuguegarao City, beholds the dream all Louisian stakeholders can look forward to.
