A suspended Treehouse

Is this a photomontage or is it real???

I found on the net this wonderful treehouse. At the beginning my attention has been kept by the strange and winding wood stairs, but then I realized that there was something strange in this treehouse…..

What is the structure of it? I can see some cables, have they hanged the treehouse just by these cables? If it would so, it would be so gorgeous!!! A sort of Renzo Piano or Calatrava for a treehouse, something of High-Tech structure for a treehouse!

Unlucky I didn’t find anything about this treehouse, so I don’t know it’s just a fake or as I told an engineering treehouse!
