For over 65 year oldS, homes need to have:  (1)  zero-step entrances;  (2)  single-floor living;  (3)  wide halls and doorways that can accommodate walkers and wheelchairs & particularly in the bathrooms.  Most older adults are homeowners & will increase in years to come.  Also may need care to stay in their homes and nursing home populations have declined.  Other options are:  multi-generational houses with in-law apartments & the “village” concept of shared services.  Try driverless cars & home-centered technologies.  LOTS OF CHANGES AHEAD.
