Architect Daniel Andersson has created a houseboat inspired by icebergs, one that sits predominantly below the waves with only its rooftop deck exposed to the sun.

From the terrace, a staircase spirals down to a 60-square-meter living space that contains a living room, head, galley, dining room and bedroom. A central atrium provides natural light, and windows below the waterline provide a view of the scenery. There's even a sauna next to the bathroom, which opens out onto the staircase so that you can run straight out and into the water.

Externally, the whole structure is shaped like a hull. Secondary pontoons stabilize the structure, but it's not really cut out for stormy waters and would be best moored in calm waters and anchored to the seabed.

The design was commissioned by the Ålands Hotell & Restaurangskola resort in the Åland Islands in the Baltic Sea. The client wanted concept accommodation to attract more tourists to the islands in the summer months. In winter, however, the sea around the islands tends to freeze, so the structures will need to be removed and refloated when the ice thaws in the spring.
