Quickly:
Standard tower from GW.
1. We stick together 3 walls.
2. We paste the top parapet, a floor of the basis and a floor of 2nd floor.
I took plastic of 3 mm and squeezed out on it a stone tile. Do not forget to cut off corners at plastic that correctly would rise.
3. We cut off 4th wall on stones, as in drawing. The top part it is pasted to already ready design.
All! Locks on walls perfectly hold a demountable wall.
We paint and go bananas!
If it is provided, doors, windows or loopholes to cut out before assemblage!
