Hi Ms Arkie. I'm paraplegic from chest down.
Door hinges exist that swing the door back flush with door frame which takes away thickness of door.
Removed dish washer & finished behind it so I can roll under counter.
Cooktop you can roll under & wall oven is awesome & wish I had that!
I have 3 2x4's (about 5") stacked which my couch sits on to make transfers a breeze.
We used cement in the bags to pour ramps at front, rear & garage door.
Grab bars like Dej said's a cheap easy diy if you know what you're doing. Make sure at least 1 side screws in wall studs.
