Concerning the space there are two possibilities. We can find an existing empty traditional house in which the installation can be developed and be open to the public,

or
the cells for the artists can be build up
inside an institute/ exhibition hall, transparent and visible for the public.

The material is a steel construction like a scaffold covered with plywood.
We  calculate 20 squaremeters per artist, 4-8 artists means 160 – 200 squaremeters.
