He is famed for designing Europe's largest skyscraper, The Shard in London, and now Italian architect Renzo Piano has gone back to grass roots to create a tiny 65 sqft micro-house with enough room for a kitchenette, shower, bed and even storage.

The wooden structure is called Diogene, has a living space of just 2.5 metres by 3 metres and is currently installed at the Vitra Campus in Germany.

The front of the building has a living room, separated from the bathroom in the rear, and the £17,200 micro-house also has a water collection system that harvests rainwater, and is powered by solar panels.
