Planning an accessible conversion of a bakery into a residential loft

Hello everyone

I am new here and looking for help with the planning and implementation of a disability-friendly conversion of a former bakery into a residential loft.
Important to me would be tips and procedures so that I can take the first steps.
So far, I have realized my ideas using software and hope this gives a small impression.



Pictures of the current condition would probably also be useful, I think, and I will provide them later. Currently, the floor and walls are tiled as usual in a bakery. Below the rooms there is a basement with large rooms where, for example, flour silos used to be. One problem is the windows which, for whatever reason, are set higher than usual. Since I use a wheelchair, I cannot look outside from any window. I hope to receive a subsidy for this from Bayern Labo.

How should I best proceed?
Energy consultant?

I think a lot of information is still missing, which I would like to provide later. I hope you can support me a little and thus help realize my planned loft.

Regards
Maiky

You are in the wrong subforum here.
This way:

Please fill out the pinned questionnaire and present the existing state as it is. Please indicate what is existing and what is newly built. Please address the accessibility, why and how many people it concerns.
Otherwise, no constructive criticism and evaluation can be made.
At the moment your planning is not comprehensible: bathroom is bigger than a one-room apartment, kitchen on the other hand is as small as for a holiday apartment.
