A Turret, larger than the usual one Heartwood Arts makes for the complete set.
6 3/4" high, ~ 7" wide, 4 1/2" door opening, carved from pine wood.
Previous inhabitants of the wood left charming markings......even Snow White and the seven Dwarfs would feel good in there :)
In the bottom picture you can see a similar one set up with some walls and people (available separately). The price is for the turret only please!
