From the inspiration of the well known concept of open space from Mies van der Rohe, this house is made with blurring between public and private space. An experiment project set up in a house. The programming is the same as usual house, but the placement of each activity can be everywhere inside the house, can be with or without boundary. The idea implementation is to make all the wall and furniture is movable. each wall has its own furniture that can be placed/moved with rail track in the ceiling.
