I'm currently building a house in Minecraft and now the roof is on. I always need so long for such a pointed roof! Do you have any tips on how this can be done faster?
You could build the house with someone. Everything is always a little faster for two.
Build rows horizontally
If you play in creative mode you can install Worldedit. Then you build one side and copy the other with // copy, // rotate 180 and then // paste.
