Three boxes are stacked and shifted to make the basic form of the house. 

The stacking not only creates a certain spatial dynamic but also represents the hierarchy of zoning. 

Each box then serves its own function; the higher it is, the more private it becomes. 

While the top box is semi-solid to make the sunlight and the view of the hill.

 The C shape looks as if it wraps the top box and gives the illusion as if the building is light and floating.

 The stacked and shifted boxes also help create a shading space underneath it that blur the line between indoor and outdoor area.
