(c)

(1) Any property purportedly established as a horizontal property regime pursuant to this chapter and otherwise complying with it, but which at the time of the recording of the master deed called for in § 18-13-104 did not have one (1) or more completed buildings thereon or which provided for additional or future construction of one (1) or more buildings in addition to those for which plans were initially recorded with the master deed, shall for all purposes be considered and treated as a horizontal property regime in accordance with this chapter.
