Superficies

Superficies is a Latin legal term referring to anything which is placed upon and attached to the ground, and most commonly refers to a building erected on land owned by another.

== Roman law == Under Roman law, ownership of a building was considered inseparable from ownership of the land beneath it. A person with the right to use the land for a superficies, known as a superficarius, enjoyed a right to use the superficies, bequeath it to his heirs and encumber it, despite not "owning" it outright. The right was known as a Jus Superficiarium.
