De la propriété du sol en volume

Land property expressed as a volume: The concept of land property in the Civil Code, unitary by principle, has always been in difficulty when facing the ubiquitous "droit de superficie", as evidenced by the never -ending doctrinal debates. The modern concept of property "volume" has responded to the social need for division of the land. However, with volume, real estate properties become incorporeal things and destabilize the classical theory of property, which is synonymous with corporeal things. This thesis defines a concept of land property appropriable and divisible relative to height, compatible with the Civil Code's land law. For this, land, including the subjacent and superjacent domains, is perceived as part of the tangibl e world. This land is then comprehended in three dimensions via a geometrical approach. Land with three -dimensional significance corresponds to a new phase of conceptualization of the land that is more abstract. The physical part, however, which the concept refers to, ie the land, remains the same; only its representation has evolved. Applying this perspective, the land expressed as a volume becomes a unit appropriable on the model of land divided in two dimensions. Consequently, the concept of property in the Civil Code under its current wording, notably clause 552, but also 518 and 544, applies to land expressed as a volume as to a parcel. This property model able to divide the land vertically as well as horizontally is also capable to organize a land division comparable to a long lease. This complementary concept is based on clauses 553, 543 of the Civil Code. Developing the monistic thesis, the ownership
