Thanks folks! I appreciate your comments -esp. the nice ones
Anyway. I have managed to take some pictures of the two miniers houses I have done years ago:
And with some 28mm minis to get the scale
The are made from plaster an plastic sheet (the roof). I had taken a mould from a master made of foamsheet. The doors and windows where casted in resin after making masters with plasticcard.
For those who are interested some WIP-pics are on my blog
