The light seems poor this afternoon, but hopefully these two shots will give you the idea. I have cut away the small steps and added resin doors from Antenociti's Workshop, building little porches with pantile plastic card.
Also you may recall the Adobes I made from Hirst Arts bricks, here are two with some 20mm modern figures from Liberation Miniatures.
I have made new doors, carefully blutacked in place and plug in window shutters. This makes the good for 28mm as well as 20mm.
I need to crack on with the ACW now and avoid starting anything else!
