The colored Clay. The set of colors and cleanliness to them, lets me make just about any building.

Depends on what kind of build you are building, if you are building a modern style build then concrete is the way to go, you will have a nice colorful palette to work around with.

I would use Raw wood because it looks quite awesome. Especially the Darker wood!

My favorite building blocks are stone bricks and dark oak, because they blend beautifully together
