Hello, I have started a new world just a few days ago, and built a shack. I decided it was time to upgrade, so I built a big castle. I spent about 3 days gathering materials, (branch mining,) and then took about 2 days to build it. Real life days btw. I'm guessing I used about 2,000 + stone blocks along with stone slabs and stone bricks. It is made completely out of stone components. I will include the download link, so you can see for yourself.
(Half of my valuable materials are inside the castle that I gained while branch mining, I have a 64 stack of gold ingots and lost of other stuff; my other materials are in my shack. You don't need to see that piece of crap, but feel free to look for it if you want, it's not too far away from the castle.)
NOTE THAT THIS CASTLE IS NOT COMPLETE! Tell me what to add in a post!
