I wasn’t in a wheelchair full time when I got my council bungalow but they accepted the need to provide me with accessible accommodation.
The bungalow that I have now was not adapted when I saw it but they sent along an OT and a surveyor to find out what I needed and what could be done. The work was all done before I moved in. The house was definitely not suitable as it was but they made it suitable.
My needs had been documented by the lady who did my medical priority. I wonder if you should preempt another refusal by discussing the possibility of having work done on an existing property. It’s perfect timing because it is the beginning of the financial year and they may have money in the coffers.
There are so few ground floor properties to begin with that to hope to find one already adapted to meet your needs will reduce the numbers even further, I would start presenting your case to local councilors and your MP. It must be heartbreaking for you to keep being knocked back.
I know every area is different but I can’t fault WNW Homes in Leeds – nothing was too much trouble.
