Here is a version of a windmill with interior.
The walls I had designed and built quickly, but the interior takes its time until I liked it.
Ground floor: Here you will find a collecting basin for the milled flour and several flour sacks.
1st floor: Here is the millstone.
2nd floor: Here is only the gearbox of the windmill.
Outside: Next to the entrance to the mill I built a shelter and on the roof of the windmill there is a sail, so that the upper part of the tower can turn with the wind.
