Q&A for How to Make a Treehouse in Minecraft

If you put a ladder, zombies and spiders can go in. Zombies are the only mobs that can break down doors. If you put a staircase, skeletons can go up. Endermen can go up no matter what because they can teleport. A more efficient way is to put vines on it. You can climb vines, but mobs can't. Endermen can still teleport and, depending on your design, spiders can too.

Make an extended room, make a cuboid jutting out from the bottom, and place the water.

Yes, though it may take a while longer, as you would need more supplies. Just double the supplies you would need for one room, and connect both rooms with a bridge. You can continue this, until you have the sufficient amount of rooms, or however many you like.

Yes, but it may take a while and a whole team of builders and a lot of supplies.

Yes.

Yes! Just expand the tree using your own items, and make that tree house bigger.

You can make your treehouse whereever you want, as long as you can get materials to make it!

Take a couple of days to gather everything you need and THEN build your tree house.

Jungle wood looks the best, but oak is a common choice.

Yes, but if you are building in Survival you will need a lot of sand and coal.

If you are focusing on the design of the treehouse, a forest biome is good. But the plains are a perfect place to build a treehouse in Survival, because it is one of the safest biomes in Minecraft.

No, it will not work in that edition.

Sure, then it would look like a swamp house. Using vines instead of ladders would look more swampy.

Put beacons with colored stained glass blocks on top. It needs to have one or two layers of iron, gold, diamond or emerald blocks underneath to power the beacons.

You don't need to use redstone to make a door. Redstone is used to open a door.

It's easier to build it on a jungle tree so you won't have to cut down logs and re-place them. (Plus you won't need shears to cut leaves for decoration.)

Yes, you can but the tree will have to be wide for you to live in it.

If you're on survival mode, save the world, edit it and turn it on creative mode, then you can break out.

Yes, but three things to consider: 1. You’ll need a lot of patience. 2. Make sure they’re giant versions of the tree. 3. If your treehouse is too large, it wouldn’t work because it would stand out too much.

You can use furniture hacks, or download mods for furniture and use it to decorate your house. You can also give your treehouse a couple of windows, and maybe some paintings on the walls.

There isn't a high chance of that happening, but if it does, fight it.

Place a stair block, walk enough to the edge of the stair to place a plank block, and put another stair block on that. Keep doing that until your staircase is as tall as you want it to be.

Yes, but if you have plans to add 'furniture' inside, it may have to be bigger.

Of course you can, but you should probably add blocks as you go so you can breathe.

I recommend you do this in creative mode. To make a colored beacon you need 9 blocks of diamond, 1 glass light (which you can find in the section of creative where there is a picture of lava) and stained glass the color you want the beacon to be. For two beacons, you need 11 blocks of diamond (start at nine and add two for each number higher you go), 2 glass lights and stained glass as before. As you have in this case 2 beacons, you first need to make a platform of diamond 4x3 blocks, then in the middle of the platform put your two glass lights. You should then see two white beacons appear; crouch and place the stained glass on top.

Anything, as long as you have the space for it. Make sure the nether and end portals have their rooms coated, in case anything comes out.

Well, they can't use them directly, but some skeleton mobs can use arrows to activate a wooden button.

Yes, if you are not in peaceful mode, then a creeper can blow up a treehouse. The modes are peaceful, easy, normal, and hard.

Yes. Open your creative inventory and select the blocks you want and need. Get some armor too, because it makes you insane at flexing.

As of March 2021, you cannot build in spectator mode. You can build one in survival or creative mode, or in adventure mode with allow blocks or canplaceon.
