I used to design houses as a sideline. My designs were top-of-the-line because they included things like properly built basement drainage systems and sumps (never saw a sump I liked), 3' eaves and properly placed windows, attention to snow removal and security, many others... AND "impared mobility".

Unreal how many people with a million dollars were shocked, and some actually offended (even my own aunt) when I explained the accomodations I made for a future vertical lift between floors. I am not making this up!
