I have copied the (so far) 4 entries to the tree house contest to the city and tried to integrate it as well as possible into a “natural” environment.
If you go to spawn and from there to the city-area portals you can see the “treehouse” portals. From the other side of the portal, 4 paths branch out to the individual tree houses.
If you have not submitted your tree house, please do so ASAP!
Elders, please go and take a look and rate the tree houses!
