Maison Shalom invested in a range of infrastructure and services to increase financial autonomy, create jobs, and contribute to the development of the Eastern Region of Burundi.
The first bank of Ruyigi was established thanks to the advocacy of Maison Shalom, which also made one of its building available to the bank. A second bank would later open in another building of Maison Shalom, inside the enclosures of the Cité des Anges.
Aside from renting its buildings to the banks, Maison Shalom started catering and accommodation services, the Guest House Frieden, and guest houses "Villa des Anges". These were the first structures in Ruyigi offering good quality accommodation and catering services. Visitors who previously preferred to staythe night in Gitega, the second largest city in Burundi, could finally stay in Ruyigi and receive all the necessary services there.
