14 retired couples, predominantly British and German, will have to dismantle their prefab wooden homes in La Xara, near Denia (North Costa Blanca), and move to another location.
The families, who purchase 2 years ago for between 60,000 and 70,000 Euros, claim they are victims of a fraud, having been assured that the properties were legal.
The properties are located on non-urbanisable land in the Montgo natural park. They do not have building licences or utility connections.
The properties were sold by a Finish company with liquidity problems, so the buyers have little hope of compensation.
