Floor plan of an accessible bungalow

I have never heard or read a bigger nonsense...
How do you come up with that? Most houses are rectangular and usually, if they are free-standing, every room also has its windows.

I’ll be a bit provocative now, but maybe it helps:

So far the question of why it MUST be an angled bungalow has still not been answered.
Basically, there are no compelling reasons for it, quite the opposite:
Every extra corner also costs more. So: a right-angled bungalow with the same floor area is cheaper than an angled bungalow. You can save even more if you reduce the floor area and go for two stories.
Especially if it is supposed to be a barrier-free, disability-friendly house, you should avoid every corner, every angle (and every wall that is not absolutely necessary), an angled bungalow already has more than needed. Why stick to this house shape if the requirement is for it to be disability-friendly?

kbt has made a very good, practical suggestion in my eyes (and I’m not alone in that). If I remember correctly, you didn’t even remotely address it. Never mind... I won’t go further into it now. You came up with another variation of the suboptimal angled bungalow.

I would say you’re resistant to advice...

You also asked Reha-Kids for opinions on the bungalow, so I know your son can’t control the wheelchair on his own and that this will probably not be certain in the future either. Possibly he can do it with some limitations, but he probably won’t become an experienced wheelchair user. That means: exactly such a person needs as straight and wide "lanes" as possible. Straight and angled bungalow... well, be honest, it just doesn’t fit.

I’ll say it straight: you have fixated on the angled bungalow, that is your wish. Unfortunately, you have a disabled child and now the dream has to be adapted accordingly.
That will always be a compromise solution.

I’m not blaming you for that, really not. You spend a lot of money on your own house, and you should realize your dreams. But then please be honest and say clearly: we want an angled bungalow because we like it so much. We want to plan the house according to our ideas but as disability-friendly as possible.
That is okay. You are not only parents of a disabled child but also a couple with your own wishes and ideas, and you have every right to that.
But then kbt wouldn’t have had to take the time to come up with a good suggestion that never had a chance anyway, because it is simply not your dream house.

I would truly wish you would make a clear statement here, because otherwise this will turn into a farce.

Either you primarily want to build a house for your son; disability-friendly and suitable for the next 20 years. Then say goodbye to the angled bungalow and take another look at kbt’s design.

Or be honest and say: we want an angled bungalow because we like it so much. It should be adapted as best as possible to the needs of our disabled son, please help us with that.
That is a clear statement and totally okay, but it is no longer a house with the top priority "disability-friendly."

Regarding Kerstin's draft and the desire for privacy: One could move the door of the master bedroom downward towards Child 2. This would reduce valuable closet space, but maybe it could be compensated with a narrow dresser on the upper left side of the plan. And for your child, I don't find the access too public. I think short distances with the wheelchair are much more important than long distances between the children's room and the living area just for the sake of privacy. What do you think?

You don't receive clients in the home office, do you, zizzy? Then Kerstin's last draft with an integrated office in the living area would be quite feasible.

Cut out realistically scaled furniture (your own in desired dimensions or some of the suggestions here) and place them in the draft from your builder. You had already drawn something into your draft once, but it looked somehow disharmonious. However, I don't remember it exactly anymore.

And played around a bit more. I think that for the plot and the desire to also offer the wheelchair user a comfortable entry and exit in the carport, the rectangular variant is still the best.

This way, there is also some distance to the neighbor in the south, southeast ..

Now with a small corner so that a cozy covered seating area can be accommodated.

The parents’ bedroom is placed to the south, southeast, child 2 / office by the entrance door. If child 2 really is there, I would build the space-saving staircase upstairs, temporarily accommodate the office there, initially place the child in child 2 / office, and from about primary school age consider moving the office back downstairs and child 2 then under the roof. Alternatively, the parents under the roof and child 2 in the current parents’ bedroom.

In the hallway in front of the bathroom, a closet niche for towels, bed linen, etc. What all 2 to 3 private rooms need.

Of course, there are things missing, e.g. Child 2 or study room or wheelchair parking space (150x180) and relatively small utility room and covered terrace.
