Article 607

If the usufruct is constituted on immovable property of which a building forms part, and the latter should be destroyed in any manner whatsoever, the usufructuary shall have a right to make use of the land and the materials.

The same rule shall be applied if the usufruct is constituted on a building only and the same should be destroyed. But in such a case, if the owner should wish to construct another building, he shall have a right to occupy the land and to make use of the materials, being obliged to pay to the usufructuary, during the continuance of the usufruct, the interest upon the sum equivalent to the value of the land and of the materials.
