EMPTY HOMES VS COMPLETE HOMES

When I want to add something to my game, I want it fully furnished. I do, however, download shells for shell challenges, as I enjoy decorating the homes others built. I usually have a harder time building a shell than furnishing and decorating, so it's nice when I feel like building, but don't want to spend too much time and energy on it. I never upload just a shell, again because I have a hard time with the outside and often end up unsatisfied with my exteriors. :S
