They look Fantastic
Any chance of a tutorial on how you painted them?
As Billchuck said, there are details on the blog, but here's the step by step of the painting:
1. Undercoat with a cheap grey primer.
2. Base coat with a sand-yellow spray.
3. Drybush off-white.
4. Mask each colour with tape and stipple on the colours.
5. Stipple a light brown around the base of the building.
6. Wash with a diluted brown wash around the base of the building and any other desired areas (e.g. window streaks).
7. Lightly drybrush the corners with the off-white
