The enclosure shows the relationship between inside and outside. The particular features: the slope site and the opening plan of this building can be distinguished.
Most interestingly, this villa has a lot of entries for many different purposes such as main entry to the living room, north entry to the kichen, west entry to the outdoor terrace. The multiple entrances create different ways of entering and experiencing the house. Each entry is the starting point for a unique pathway around the house. Moreover,The furniture and settings such as bed, sofa and etc also effect the circulation.
For vertical circulation, the spiral staircase is the main connection, combining servant room, studio, guest room on ground floor and living room, master room, kichen on upper floor together.
I analyse this building by myself. Firstly, I use grid and L-shape to analyse geometry of this building. But it is not very appropraited. Then I tried to use the golden ratio (1:1.618). It is perfectly suited to this building, both plan and section.
