Orc towers
Orc towers are again a domain where the community fantasy and the fantasy community :) can reach outstanding levels, as shown in the pics below. Shape is more or less standard, still outcomes can differ a lot.
They are basically made of wood, stones, bones and metal leftovers. Wood normally prevails, but surely it is not the only option. A strong influence from warcraft is undeniable either.
Bottomline is, they have to look absolutely unstable and standing up by miracle. You can use almost ANY material and often even some other race's buildings as a starting point. Again greenskins reveal to be the most creative and flexible of all armies, the one everyone can enjoy the quickest.
