This is a killer use case, but you should also take a peek at the Human Factors Handbook -- it's got great information about how to architect buildings like homes that will help you avoid some pitfalls I've seen in custom homes that I've been the second owner of.

I'm curious here but can't find that title. Do you mean the "Handbook of Human Factors and Ergonomics" by Gavriel Salvendy and Waldemar Karwowski?
