The GH house faces west, so the main façade of this house is only sloping grass, and the façade material is made of printed concrete and wood.  The large number of large trees in the western area helps reduce heat during the afternoon.  Zoning in the west is a secondary area such as corridors and prayer rooms, so that when the afternoon sun comes, it can make a barrier to the heat entering the main rooms.  Living rooms, children’s rooms, and main rooms have openings to the south or north, so they don’t direct directly toward the sun.  All the main rooms are focused towards the inner garden, which is also the center of this house.
