When establishing itself in a new city or country, the Cenacle looks for a house with a dual purpose: to house the community and to host retreats. Unless they are fortunate enough to find a benefactor who offers a suitable building from the very beginning, the founders usually have to rent a temporary location. Purchasing, or then possibly building, are only considered at a later stage.
The Directory of the Congregation specifies which criteria to follow when choosing a house. Once on site, the sisters adapt the layout.
At the invitation of Pope Pius XI, the Congregation decided to transfer its motherhouse to Rome. This was an opportunity to launch a new construction on land on the outskirts of the city, in a rapidly growing neighborhood.
