Explanation of Article 663
The article clarifies that if a person constructs a building or plants using materials owned by others on his land, he becomes the owner of those materials because the structures are considered part of the land. He must pay their value to the owner, and the owner cannot demand their retrieval because they have become part of the land. If the owner of the materials suffers damage as a result of their use, he must be compensated for this damage, unless the parties agree otherwise.
