1. A Mansion
Now you have probably seen alot of mansions built. After seeing these mansions you're probably thinking it's gonna take a while to build one. To your surprise, it doesn't take very long. The reason I like building a mansion is because after building the mansion itself, you almost have control over the entire minecraft world. Imagine it like this, with the resources it takes to build a mansion. Once you get all of those resources if you're in creative or survival mode, you're pretty much good. Now I don't build a standard mansion, I make my mansions like it is my secret fort. I build all sorts of hidden piston doors that lead to secret rooms,secret passageways, and even "TNT Shelters". The reason I build all of these is because if you build this mansion on multiplayer on xbox 360 or on a Minecraft server, people are gonna be jealous. So you should always have secret passageways that holds your diamond items, a secret room that you can get to if someone is trying to kill you, and a TNT Shelter made of obsidian to make sure if someone puts TNT everywhere, you can get to safety.
2. The White House
Now I know some of my viewers are not American, so the white house is basically where the president lives. The reason it's fun to build the white house is because it's super fun to be a owner/admin of the MC Server, and live in a huge double mansion. It's also super fun because who doesn't like to pretend being the president? I mean seriously, you get a big mansion, you're super exclusive, the president is the most powerful person in the world, etc. So why would a server admin not have a white house? I mean honestly, some people just assume it won't be fun. But it's worth the time spent in it. You get alot of offices, secret rooms, etc in a Minecraft server. Also if you build The White House, alot of people will want to see it. It's so cool to walk around the white house in Minecraft and see what it's like to be the president. So if you haven't already I would build The White House because the United States of America is awesome!
3. A Redstone House
This is kind-of unexpected. A redstone house. A redstone house is not made of redstone but it has many features involving redstone. Redstone Houses are really fun to have, with automatic doors, automatic mob killing machines, automatic floor changers,automatic on/off lights/, and more! But there is a reason it's on the number 3 spot, it's hard to build. It takes alot of time and effort and in the end if you are not familiar with redstone very well then the redstone house may be useless! A redstone house is really cool and you can show it off. But it might even be griefed or destroyed. So I would reccomend building this on a server you know their are no griefers on.
So those are the best things to build in minecraft! I hope you try out some of these ideas and build them. If you do please tell me if you did and what your friends reactions were in the comment section below! So thanks for reading and have a great rest of your day!
