A new €12,000 flat-pack three-storey home has been created and can be built in just four hours.
The brainchild of engineer Dr Mike Page, the compact house requires no planning permission and measures just 3m tall and 4m wide.
It can sleep two people comfortably and contains a lounge, staircase, kitchen, bathroom and bedroom over three floors.
''The QB2 is practical and fits together easily. If someone can put up an Ikea Billy bookcase then they can put this up.
''It goes together like flat-pack furniture, although when a customer buys it they will get the finished product and won’t have to put it together themselves.''
The compact home doesn't need planning permission because it is under 4m in height.
Mr Page, who teaches at the University of Hertfordshire, insisted that a couple could live a ''comfortable modern existence'' in the home.
''Inside the QB2 there is a lot of practicability, with things such as the dining table being able to move while still attached to the wall, giving more room to move around and also lounge on the sofa,'' he explained.
He used clever techniques when designing the house to make the most out of the space available such as using a bookcase that doubles as a mini spiral staircase.
''All the volume of the cube is used and we've got cork flooring throughout which is nice and warm and everything is insulated,'' he said.
The house starts at around €11,000 to build yourself or €12,000 for Bolton Buildings to erect it.
The deluxe package costs almost €50,000 and includes a shower, furniture, LED TV, kitchen appliances, bed and mattress, lights, switches, wiring, plumbing, triple-glazed windows, chesnut cladding, cork tile flooring and is fully painted throughout.
The QB2 made its first appearance on George Clarke’s Amazing Spaces on Channel 4 last week.
