How to build in creative mode Minecraft? - 1

You can look up generalized Redstone tutorials on YouTube, as wiring mechanics tends to make a general "build" better if building modern houses and the like.

As for building, if you've got a widescreen monitor or dual monitors, you can slide a picture of what you want to remake to the side for the extra room, in the case of double screens, you can full screen MC on one and view the project on the other.

You can also do "floor plans" on MS Paint, just zoom in to 800% and turn on grids (CTRL + G is the hotkey). From there you can use the pencil tool to plan out the thing from the front, the back, top-down, interior, etc etc using the different colors for each block (use generalized colorization if you're working with one type of material, for example, dark colors for exterior blocks, light colors for interior blocks like flooring).

But mastery of Redstone wiring is a must, as making a simple 2 floor elevator takes up a LOT of room, regardless of how compact it might seem.
