This article presents the possible legal aspects of introducing the concept of threedimensional real estate (spatial parcel) into the Polish legal system and the need to more precisely define the spatial boundaries of property rights. This issue is presented with reference to the legal principles that exist in the US, Sweden and Norway. The need for new institutional arrangements is preceded by a discussion of the current registration policy in Poland for the individual ownership of buildings and the establishment of rights of usage. The article also includes comments on the necessity of establishing a multi-dimensional real estate cadaster that enables the registration of individual spatial properties (including the particulars of buildings, structures, locations, constructed sites, and technical infrastructure), all associated legal rights and a three-dimensional visualization.
