This is a great futuristic architecture designed by Kotaro Ide from Japan. The Shell house  represents an modern concept which creating a balance between the futuristic man-made structure and the environment, all in a perfect harmony.  If you kook closer   the architect used reinforced concrete to construct two elliptical shell forms, in shape of J , with a big courtyard into the centre.

This is more like a vacation house far away from the noisy of the city.
