A Dutch architect plans to construct the world's first 3D printed building inspired by the Earth's landscape. Janjaap Ruijssenaars hopes to create the buildings, which he estimates will cost £3.3million- £4.2 million. 
The 3D buildings — a more direct way of constructing — will resemble a giant mobius strip — a continuous loop with only one side, 'BBC News' reported. Ruijssenaars is working with large-scale 3D printing expert Enrico Dini on the project. The industrial sized 3D printer uses sand and a special binding agent to create a "marble like material" stronger than cement.

However, the 1,000-sq-m buildings would still require concrete reinforcements , he said. 
"For me as an architect it's been a nice way to construct this specific design — it has no beginning and no end and with the 3D printer we can make it look like that. In traditional construction you have to make a mould of wood and you fill it with concrete and then you take out the wood — it's a waste of time. You can print what you want — it's a more direct way of constructing ," he said. He said the first "landscape house" should be in position by 2014.
