If you really want to buy expensive houses in the shop do it, otherwise with a few simple steps you can design and build with balsa wood a great Warhammer house. Plan of the trenches, perhaps the levels on which to climb (watch towers and upper floors for archers and mages). All the details are essential. You can add a couple of dried roots and arba as desired to enhance the effect. For the roof, use paper, cut the paper strips, glue and cut it again to give them the right shape.
The smooth walls of the base, are then decorated with strips of balsa wood to build more subtle reinforcement and to give the right look to the medieval "danish" house. With just a couple of intersections will give a nice look to the building!
