I've built this plantation style mansion in Minecraft in a week. It's not huge because it's really hard to get all of the blocks in survival. Time of braking the blocks is longer, you can easily die but this is a structure made in Uvicraft server so you can vote daily to get 30 minutes of flying so it's not as hard as the regular survival would be. You can see the big roof alongside with white terracotta walls, porch etc. My friend MrStipe had been helping. I hope I'll continue building structures like this. I've also claimed the whole building. Since the beginning of a project, it has been a lot of fun!
