Mr Harold: Those are just balsa left overs from previous buildings, some green stuff tubes and bits for details and a lot of randomness. For the corrugated iron, I used some corrugated paper. Not sure how it's called in english tho.
Dewbakuk: The pagoda and houses are from Plasticraft Games. The trees, little pavilions and the portal are from decorsminiatures.fr. I used some plastic sheet for the portal's tiles tho.I don't know who made the castle and rampart since I traded them. I Made the stone lanterns with the computer and printed them. Unfortunately, I din't find any company willing to produce them.
PS:Forgot to say the pavilions are pretty small. Probably better for 20 mm or smaller minis. Not that buddies at the club care but if you're like me, don't buy them. The site has others.
