[6] At the research level, the faculty takes part in the Doctoral Commission of Engineering Sciences and Technology, Construction and Urban Planning (CDI).

This institute is further made up of several research centres including: Other laboratories, centres and institutes were founded on particular campus, as LoCiLoCaL in Tournai,[7] Metrolab in Brussels (a trans-disciplinary institute of the Brussels Capital-Region jointly organised by UCLouvain and the Université libre de Bruxelles)[8] or the Doctoral Seminars on Sustainability in the Built Environment which are organised by eight Belgian universities (Hasselt, Ghent, Liège, VUB, ULB, KU Leuven and UCLouvain).

[13] The Dutch-speaking equivalent of LOCI, the KU Leuven's Faculty of Architecture, is still located there, on its Sint-Lucas Brussel campus.

In reality, it is a vast settlement abandoned by the Meurice Institute of Chemistry (nowadays part of the Haute école libre Lucia de Brouckère and located on the CERIA campus in Anderlecht), hidden behind residential buildings and straddling Ixelles and Saint-Gilles.

[18] In 1965, a vast international-style building was built on the Chaussée de Charleroi, n° 132 in Saint-Gilles, by architect Émile Verhaegen,[19] also founder and president of the UCL-Saint-Luc research centre in Louvain-la-Neuve.

The Wallonia-Brussels Federation decree of 13 December 2007 grants universities the right to organise studies in the field of architecture, only if they incorporate one or more architecture schools (ISA, Instituts supérieurs d'architecture, which were a separate type of institutions of higher education, next to universities, colleges and schools of arts).

[21] During its first year within UCLouvain, the newly established LOCI Faculty kept settled in the ISA Saint-Luc buildings on the Chaussée de Charleroi.

[25] In what was at the time the independent commune of Ramegnies-Chin, the Passy-Froyennes Institute was founded in 1904,[26] with a vast new neo-Gothic building that still houses Saint-Luc Tournai today.

[35] However, like in Brussels, the university started establishing plans for an independent and proper architecture campus in the Tournai city-center.

In 2012, the UCLouvain took over the Hôtel des Anciens Prêtres building (now the Hôtel des Architectes, which currently houses the administrative services),[36] bought from the city of Tournai, as well as a former building of the State Archives in Tournai (Archives),[37] which itself had moved to the former site of the Casterman printing house in 2010.

Portuguese architectural firm Aires Mateus was appointed to design the new site, including the construction of a deconstructivist connecting building.

[39] In 2017, the Tournai campus of the University of Louvain was inaugurated,[40] with its main entrance located rue du Glategnies.

[43] The Faculty was linguistically separated in 1964 into the Dutch-speaking Faculteit ingenieurswetenschappen and the francophone Faculté des sciences appliquées.

From 1973, the programs for the last three years of civil engineering were given at the new Louvain-la-Neuve site, while the candidature degrees (undergraduate) were still being taught at Heverlee.

The deanship and the central administrative headquarters of LOCI are located in Louvain-la-Neuve, in buildings still shared with the School of Engineering.
