Part of tree house

This is wonderful! I like the roof build right around those trunks that come right through. :-)

The whole of the tree house is fixed to the trees using no nails, screws or other fixing devices that may be harmful to the trees. Also, as you can see form the photo, there is plenty of room left around the trunks and branches for the trees to grow.
I'm not sure, but I think this is the largest tree house in the world!

Anyone, please correct me if I'm wrong.

Certainly is enormous. I wouldn't be surprized if it were.
