A Serbian maths professor has celebrated his retirement by moving into a house he built himself entirely out of plastic bottles.

It took five years and 13,500 bottles for Tomislav Radovanovic, from the central town of Kragujevac, to build the 60sq metre house.

He told the national news agency Tanjug that he hopes to enter the Guinness Book of Records and has already sent them an application.

Only the foundation of the property is concrete, and all other parts of the house are made of plastic bottles that he had been collecting for years.

Even the kitchen furniture and windows are made of plastic bottles.

Radovanovic said his former students had helped him build the property by collecting the bottles he needed.
