The Squirrel Tree now has a bit more landscaping. The grass and front path have been finished, and it's grown some extra ivy and foliage too. I've also weathered the side room a little.
I haven't decided if there is going to be a door or not. Perhaps my squirrels are very welcoming?
I repainted the inside to make it a little more tree-like and painted each floor. There's a light dusting of 'moss' to act as a carpet.
And I've positioned the chimney so I know for sure where the fireplace ought to go now.
