The main design of this house is the front facade, it was a 1-storey house, then it changed to 2 floors to get the new soul and visual for the house.  The previous layout was very old indonesian houses, with the two separated living room, one for the guest and the other for the family. Then it changed to an open area living room, so the activity of the family  can become more integrated in one big room.  

The house has no backyard, so the ventilation is only works with air conditioner. It changed to be a small backyard to make natural ventilation  and new visual from living area.
