Hello all
I don't know if this is already on the forums or wiki (and you probably know what I'd say next :D ) So I'm not gonna brag, but here's a tip for efficient building. This tip may not work so well at the start, but with a little mining, (2 steel only to make screwdriver) and of course your building materials, it will work fine.
The trick is, make your house out of slabs. Now this may sound crazy at first, but if done right, it will let you build your house with 2x less wood (or a 2x bigger house whichever why you like :D) Heres how you do it.
METHOD 1: The Screwdriver
You have to first make slabs of whatever material block your using, and just build walls and ceiling out of it. Now use aforementioned screwdriver to rotate the slabs by rightclicking them with the screwdriver selected until they fit in and close the gaps.
METHOD 2: Standing on walls(If you don't have screwdriver)
In this method you stand on top of the walls you are building and place slabs while looking down. And to make ceiling, get inside the walls onto the ground, and elevate yourself using blocks placed underfoot (or /fly on servers that allow it)
until your eyes are aligned with the top of the walls, and aim at the top slab of the walls and start placing slabs. The reason why you have to make house this way is because otherwise the slabs tend to spawn in such a way that the walls and ceilings look like floating shelves. This method is actually the more complicated because of this, so the screwdriver method is actually recommended due to you simply being able to stand on the ground and built the whole thing.
Sorry if my post is a bit confusing or unstructured because I'm not used to posting stuff like this
Feel free to correct mistakes in my post as I am a bit of a noob and have just discovered this.
If you don't understand, tell me and I will try to post a photo/video of this being done (or can someone else try too who can maybe do voiceovers using mike because I can't as I have no mike (and also I probably wouldn't want to if I did :D )). :)
