If purchasing a home or need to make your present home to handle special needs, particularly as you get older, the principle of UNIVERSAL DESIGN  simplifies life  for you and those around you.  Universal Design actually benefits all ages and abilities.  A home with a ground-level entry provides easy access in and out and wide enough to accomodate a wheel chair.  Also check width & slopes of sidewalks around your home to ensure that they, too, have easy wheelchair access.  Single-story homes give better maneuverability if you become physically impaired.  If you must use steps be sure they are covered with a non-slip surface and are well-lighted.  On the ground floor is there a bedroom or bath to use if you cannot climb the stairs, even for a short period of time.  Kitchens have become FAMILY ROOMS.  Again ability to get around in a wheelchair or walker.  Push-pull lever faucet handles are better than standard knobs.  Need easy access to drawers and cabinets.  In bathrooms have handrails and grab bars, but be sure walls will hold these when installed.  A chair or bench could be used in a tub or shower and handheld shower heads are good if you cannot stand to shower.  Keep UNIVERSAL DESIGN when you buy a new home or remodel your present one.
