Mallorca has 55,256 homes built on rural land, 15,817 of which could be contrary to current urban planning regulations, according to data from the project Houses That Don't Exist, presented this Monday to the Official College of Architects of the Balearic Islands. The research, led by urban planner Miquel Rosselló Xamena, puts figures to a phenomenon often invisible in public debate: the proliferation of homes on rural land.
