A little progress..
Some windows made from Evergreen profiles and clear plastic
Painted with "buff" colour to simulate wood
Treated with AK Heavy chipping fluid
Then painted with white colour. The white colour was then "chipped" using toothpick and an old brush with hard hair.
After chipping the window was weathered with AK wash. Some white highlights were added (drybrush with oil colour)
And new doors made from plasticard and Evergreen profiles
