A vegetal layer that serves as the skin of the building externally covers the thick wall. That is not all, this eco-friendly structure is also has a dense wall made of an organic concrete with pores, wherein several plants can grow creating a unique look for this wonderful creation. This structure is great because rain and soil are drained, treated and reused, which means a complex eco system is formed just within.
