The design is broadly inspired by the 4ground building that appears in the kickstarter (I loved the pale blue windows idea)
and also in this case is build with forex. On top of that I used 1mm balsa wood for the timber cover...I am not fully happy of that. i should carve more deeply the balsa to have the effect of separate wood boards.
I covered the external walls with plaster before painting to reach a raw wall effect.
Fairly fast to build and good overall effect. It overall required 2-3 hours from start to end !
