The Cube Houses of Piet Blom, 1984, Old Port, Rotterdam, the Netherlands. Another pinner said one of the houses is a hostel, stayed there, and liked it. (Update: The entire complex is now a hostel.)
Netherlands Cubic Houses in Rotterdam. Architect Piet Blom turned a parallelepiped an angle of 45 degrees and put a hexagonal pylon at an angle along with it. The houses have three floors. The entrance is on the ground floor, a guest room with a kitchen is on the second floor and two bedrooms and a bathroom are on the third floor. A small garden is sometimes placed on the upper floor.
