The idea of a tree house seems as completing the synergie, enhancing the idillyc atmosphere.

The concept of the tree house dived into the inner childhood memories.
'As a child, I used to love nature. There was this one prune tree, right in front of the house, that I used to climb into every day and spend hours playing with its leafs. It had a small hollow that birds used to visit and large, confortable branches for me to climb' - seems like an universal description of childhood practicies.
