There's plenty of guides out there. Look around for building tips. You can't just build a big epic house easily. It takes many failed attempts, tips, pointers, and practice. The more you build, the better you get :wink.gif: I'm currently just getting out of the box house with one material, so I'm no help to you. Keep trying though, and I'm sure you'll get there.
No one can teach you how to make an epic house... You need to learn yourself
Build some blueprints before you build! What I mean by blueprints is just open up Microsoft Paint or something and put a tiny pixel for each block, so you'll know exactly what you're house is gonna look before you build. Just start drawing a blueprint. tweak it a little and start building it.
