The idea is to make a space from two same modules, which have the dimension from the first plane's mould.
This combination is one on an infinity, the space is determined by where the plasters are.
A few space composition that we can do with two modules.
There is two different sides: the first is viewed from outside where there is no noticeable horizon, the second from inside where we can see the size of the space and the height due to the different layers which are linked by the human dimension from the module, which is formed by the two from the bottom. The third layer, is a twice repetition from the module.
Without horizontals or clear separation we cannot
understand the size of the space in height.
When we add horizontals at human dimension
as noticeable stage, the space is hierarchized.
