Is there a limit to the stuff I can build in Minecraft?

I've built an elaborate world. It just hit me that it would suck if I hit a capacity of what I can build.

As far as I know there's only a height limit.

Nope your good

There's a height limit, and a section of space where the world ends, it is limited.

You can build as many things as you would like in Minecraft, as long as it stays within the height limit, which is 256 blocks above bedrock (The bottom layer of the world).

On the PC version, the world is 30 000 000 x 30 000 000 blocks (area).
