The House Y2 boasts a unique layout. It is essentially made up of two separate structures that are connected by an underground tunnel. As though straight out of a Victorian novel, the tunnel could be likened to a secret passageway. Except, of course, it is not a secret at all. That is because the tunnel simply bridges one part of the House Y2 to another.
Designed by destilat Architecture + Design, the House Y2 was created in such a way as to make the most of the views of the Danube River. Built at the foot of the Pöstlingberg mountain in Austria, the House Y2 has essentially split up the living area and the sleeping quarters.
