Reports added that the tree tower would only be structure with timber from sustainable managed forests. Each wooden tree house is to be built on stilts and boasts balconies, carvings and turrets that wouldn't look out of place in a Potter adventure.

Tree houses will be connected by a rope bridge and can be approached by a secret tunnel hidden underneath a raised wooden walkway.
