Barrier-free construction - what is important?

It was not really about funding. I first wanted to know if it makes sense, in the case of a complete gutting including ceilings, to maybe plan one or two barrier-free apartments in advance and what is specifically needed for that. I will then take another look at the [159er Merkblatt].

Barrier-free is affordable. Door widths 1m. Showers are level-access and equally wide. Also ensure enough maneuvering space in the bedroom and hallway. Avoid steps in the outdoor area as well. Toilets please use these higher models.

It wasn't really about funding.

I meant less the money and more the influence on the "standards" of the market through the funding conditions. They are to some extent a reflection of what the cartels connive.

Socket at light switch height
Handrails on both sides even with one step
Space for stacking washing machine and dryer
Threshold-free from car to terrace
1-meter-wide doors
Floor-level shower
If there is space, plan a bathtub that is lift-accessible (narrower, longer)
Washbasin and no washstands with cabinet. Then you can sit down for brushing teeth, etc.

I would design the floor plan for wheelchair use. Then rollator and nursing service fit into the bathroom and bedroom
Take a look at the website of barrierefrei.

Do you, as landlords, install the kitchen? If yes, I would offer a workspace for sitting. Refrigerator, dishwasher, oven built up higher

Wide parking spaces

Ramps at stairs

The need is already there. Not everyone with disabilities is ready for a nursing home

Wow, thanks already for the tips! When I read it like this, so far it is essentially the 1m wide doors that would actually cause additional costs. Floor-level showers were planned anyway, and the height of the switch or the oven doesn't really make it much more expensive. I do think that such apartments could also be rented out well.

The extra space is the expensive part and the floor-level shower. I would only hang the toilet on a solid wall or a strongly reinforced wall so that support handles can be installed.
