The world's thinnest house has opened its doors in Poland.

The abode, which measures just five-foot wide, has been constructed in Warsaw and contains all the necessities such as a kitchen, toilet, shower, eating area and even an upstairs bedroom accessible via a metal ladder.

''You don't need that much space to live in, so it is worth considering building smaller scaled, cheaper housing.''

While construction has been completed, there was little room to throw a housewarming party, but architect Jakub Szczesny says the property has everything someone needs to set up a home.

He said: ''It contains all necessary amenities such as a micro-kitchen, mini-bathroom, sleeping cubicle and tiny work area, all accessible via ladders.

''I think plenty of light is most important in order to eliminate the fear of the small space.

''Research shows we are approaching a social disaster because too little living space is built.
