The plan

I think I've come up with a downstairs floor plan that I'm happy with. The room to the right in the drawing will serve as a family room or den for a while. However, we are planning for the possibility of having to care for Tom's parents in the coming years, and the room will be easily converted into an in-law suite. It has direct outdoor access, as well as a bathroom and its own washer/dryer. Even if we never have to take care of Tom's parents in our home, having this conversion possibility is a good idea for aging in place. We are planning for the bathroom to be as ADA-compliant as is reasonable, which is why it is a bit bigger than a typical 3/4 bath, and also why I put in pocket doors where possible.
