its easier to build more detail if its bigger. Instead of making it small like a real lego set, build in in first person scale of your avatar as a real building.
assuming we are the little blocko guys in the game:
rooms should be like 12 feet tall or so, with all the space a normal room would have.
look at other peoples builds for ideas, or get inspiration from pictures of real things you google.
notice how any building or house (or structure) does not have 1 standard wall design flat across, but uses multiple colors or support design.
windows are almost never symmetrical to each other, nor is the building itself usually ever.
build something that you feel you can force people to take 5-10 minutes to look at rather, then fly over in 5 seconds and feel they have the general idea of what you made.
Personally, i build so that a person could spend 2 minutes looking at any one room and be impressed. I dont want to spend days-months working on a project to have someone not care.
