Some house architecture designs are actually mesmerizing and genuinely deserve a mention. The Kaidannoie (Stairs House) by y+m design office is an ideal representation. It’s a unique house in Shimane, Japan that has the roof made up of stairs. One can actually climb up and down the roof stairs. There is a smart solution for rain water. The open spaces between the stairs are covered with clear glass to protect the house from rain. This kinda house designs are not what you come across every now and then. On personal note, I loved the way this house is designed.
