Total floor area 107.77m2
Construction period 8/2005~4/2006
Project Studio PRANA
Construction Separate order

The roof is covered with grass. The client wanted to live without air conditioning and wooden exterior, so I proposed clay walls. This is the first work for Studio Prana of a full scale of clay walls house. Because of the fire performance of earthen walls we were able to outfit the wooden and clay outside wall with the fire community standards. For this project ventilation has been particularly considered for the northern planting and green curtains with the help of plants. Summer comfort has been realized without relying on air conditioning.
