The case is a large flat layer apartment on the top floor. Developers intended it to be resided by one family of many people. But the case is a family of only three. So the finesorted functions of the original building appear trivial and cramped. In view of this, we have done large changes to the plane layout of the whole space. We have broken the conventional family pattern. We keep the basic functions needs and most of the functional areas have been blurred. But the functions of the house itself have not been missed. Designers use a beautiful curve running through the different areas. Home is not a layer of the same.
