Soon you'll get hold of a stonecutter, which you can use to make stone constructions. It's great for making castles.

You need a lot of iron to make those iron wood poles though, blocks are big in the game so you need a lot of space to make a realish castle. Also RIP FPS.

I personally prefer to make smaller wooden buildings that are more spread out, also saves your FPS a bit.
