Greetings,
If you are still looking for "tips" and want to get complicated/fancy,
I have seen columns used called sort_order more than a few times.
This should not be too hard to maintain for things like a few
buildings, etc., where the lookup table does not change much over
time. You would then have another option for your "oder by" clause.
cheers,
