12x9.6m 2 full floors, basement, attic, 4 children's rooms

Hello Katja, we don’t have to, but at my age my mother wasn’t a wheelchair user either. So you never know what happens, and age-appropriate building means for me also considering things like that. Hence also the bedroom on the ground floor. If I put the shower in a 1m niche, I would lack space in case of need. The guest WC is also conceptually designed so that it can be easily removed if necessary to provide even more space in the bathroom on the ground floor.

If accessible for disabled people, then according to DIN standard. Everything else is just compromises. Feasible, but not nice. Also pay attention to a barrier-free entrance.

No one ever knows when it will hit them. Father had a stroke at 63, resulting in hemiplegia. Girlfriend has MS at 32, repeatedly uses a wheelchair. Friend had a stroke at 30, walks again, but every step is difficult. We have the stairs on a load-bearing wall to install a stairlift. Not every disability means immobility from the chin down.

So my grandma is 97 and until two years ago still crawled up her steep stairs to the upper floor. Now she also sleeps downstairs, but she is far from needing a wheelchair. We have no one among relatives and friends who needs a wheelchair in old age. Most die of cancer beforehand.

Let's all hope to stay healthy into old age... but in case that's not so, I have expanded the shower to 150x150... and sketched the window in the guest toilet.

So, I think that's a bit exaggerated now. You can't plan for all eventualities "for later." Then you should rather consider moving house, if you're already thinking about a later separation of the floors. Ultimately, the basement with the utility room etc. might no longer be accessible. I am young, 50, and know that due to surgery etc., not everything always runs smoothly over 2 floors. That's why we have a planned shower on the ground floor. I can also use it with a narrow wheelchair if necessary. But it goes too far if I have to confront disabilities that may not even occur in everyday life right now. Then you have to build a bungalow now. Period. Sorry, but it is what it is... and not how it _might_ _possibly_ turn out. The bedroom is too small for that, the office too convoluted, etc. This simply isn’t well thought out.
