Who said that the house can be only a shelter? Look at this Stairs House which is a beach-side residential home in Shimane Prefecture, Japan designed by Y+M Design Office. A façade of this unusual dwelling forms a staircase to the roof, so you can climb on it. Claimed as coolest house ever, the Stairs House or Kaidannoie combines the family home, space for communication and area for playing. The stairs construction also provides the house with the necessary ventilation and lighting. Kaidannoie was created for the family of teachers who wanted their house “to gather people”. The house looks really extraordinary. Well done!
