For now to build something is take to short time, most of time is gathering resources and then after you set a place for a house using a hammer and hitting on ground for couple of time the building is already show up. I think if you build something is more realistic to show more stages of construction like: show foundation, build wall by wall, add windows, and finally add the roof. (if possible to build something, brick by brick) like in real life. Building a house or a tower to be more complex.
Sorry! I don't speak verry good english!
