I'm pretty sure it's just walls from Level 21 on. I've upgraded my Castle Recycle and Boxingham Palace to Level 26 to get some extra wall sections, but have left my Barbarian Castle at Level 20 as the walls for it are much, much cheaper to buy directly for 100 Elixir each. I could try to Level up my Castle Recycle to Level 30 to see if it ever changes to a free Tower or Gate, but I'm not sure it there's enough time to do so. Once I'd gotten my Castle Recycle and Boxingham Palace to Level 26 and had enough wall sections I switched to buying more parts for my Barbarian Castle, and more of the Windmill and other Decorations we can buy with Elixir.

Maybe if someone else has a ton of Elixir and is closer to Level 30 they can earn more free Walls and see if it ever changes.
