I have a ranch, bedrooms all on one floor but I'm still thinking of a retirement community. Why, well for one thing the community and house are designed with an eye toward an aging individual. What that means is everything is flat, no steps or stairs anywhere which is great for a walker or wheelchair. Also bathrooms have several grab bars and usually a shower that is handicap accessible. Doorways are also wide enough to get a wheelchair/hospital bed through. Now this is not to say that you will be in a wheelchair but accidents happen and it's nice to know that your home can accommodate your every need without doing last minute renovations. The community is also designed to be supportive, in that they usually take care of all snow removal, grass cutting etc. and have a center where you can meet others in your situation. Well, that's it for me...I wish you all the best !
