My requirements include:

Bedroom of 12'6" by 14" minimum.
Large walk-in closet in bedroom.
Larger than average bathroom.
Walk-in shower.

I am getting a lot of advice on an elevator or "change the design so you won't be in trouble when you are elderly". But again, as I age, I think there will be a time where it will be a good idea to simply sell and move close to my son, who will be in (yuk) Michigan by then. I see myself in a senior apartment complex or community. I've lived in two of those up till now and liked it.

But the advice about aging is causing me to think. I'm 60, I am not in ANY denial about getting older, George!
