I saw some works here and i wonder where people get the buildings and other stuff ? Is FFG selling them and i cant find them anywhere ? is there any specific place or its owner's creation ? some look pretty amazing.

There are many companies out there selling wargaming scenery compatible with Legion.

For example, you can check these resin kits:

thanks for the links dude

etsy is also full of people who sell Legion terrain, the shipping is too high most of the time to Canada but if your in the states it shouldn't cost too much.
