All my interior and outside doors were widened so that theres 4 or 5 inches to spare on most. Front door even more. And level access. Makes life way easier.
If you are serious about using a wheelchair for the rest of your life you gotta accept that you need a bigger organised plan. And you will need to break a few eggs.
My plan cost a fortune, took me 10 yeras to pay for it. Bigger doorways was a minor part, I extended the house, downstairs by lots, and knocked down walls and made it more open plan. In a kitchen you need space. You need room to move away from cupboards and ovens and to be able to spin around all over without worrying about hitting stuff. Same in a bedroom, you need space to move, away from a bed. And doors that are 800mm wide that swing both ways (not like that!). So you can just drive into them from any direction. You need a kitchen that you can use with cupboards that pull out racking inc the high ones that pull down so you can reach.
You need low maintainance, everything. So no paintwork, All plastic. No carpets (I did the whole downstairs in large grey ceramic tiles or industrial carpet tiles.) Its easy to swap 2 or 3 tiles when they wear or you spill something which I do all the time! And wheelchairs trash carpets. They dont even touch tiles.
You need a well constructed wet room. With enough room to move! You may need carers in there too.
And a lowered floor minivan so you can drive etc. Or at least sit up front. And parking space with easy access.
Even if it means moving first because otherwise you are throwing good money at the wrong property. And the council may help wih changes. They helped me.
