I built the walls out of foam board, making an inset for the doors. Below you can see the basic building structure with the doors and buttresses trial fitted to one side; beside it is a 40mm figure for size comparison
I made up the roof with cardboard. I used my favourite method for buildings, printed papers. These were cut to size and stuck on. The doors were painted and glued in place. After that I added tbe buttresses and painted them up to match the stone paper. Below you can see it the tithe barn finished on its base, about to receive a delivery ..
I want to add two more half timbered buildings to the village - I've decided to make these myself.
