I think a W-bungalow with 130 sqm and 2 single bedrooms, 1 single room and 1 shared room fits better, because every room should have a window and with a square bungalow there are too few exterior walls.
I have never heard or read a bigger nonsense... How do you come to that? Most houses are rectangular and usually, if they are detached, every room also has its windows.
I'll be a bit provocative now, but maybe it helps:
So far the question why it HAS TO be a corner bungalow has still not been answered. In principle, there are no compelling reasons for it, on the contrary: every additional corner also costs more. So: a right-angled bungalow with the same floor area is cheaper than a corner bungalow. You can save even more if you reduce the floor area and build 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), a corner bungalow already has more than needed. Why insist on this house shape when the requirement is disability-friendliness?
kbt has made in my eyes (and I'm not alone in this) a very good, practical suggestion. If I remember correctly, you did not even remotely respond to it. Whatever... I won’t go into that any further now. You came up with another variant of the suboptimal corner bungalow.
In my opinion, you are resistant to advice...
You also asked for opinions about the bungalow on Reha-Kids, so I know that your son cannot control the wheelchair on his own and that this also probably won't be certain in the future. Possibly he can manage it with some restrictions, but he will probably not become an advanced wheelchair user. That means: especially someone like that needs as straight and wide "traffic lanes" as possible. Straight and corner bungalow... well, be honest, that just doesn't fit.
I'll say it straight and free now: you have fixated on the corner bungalow, that is your wish. Unfortunately, you have a disabled child and now the dream has to be adapted accordingly. It will always be a compromise solution.
I’m not reproaching you for that, really not. You spend a lot of money on your own house, so you should be able to fulfill your dreams. But please be honest and say clearly: we want a corner bungalow because we like it that way. We want to plan the house according to our wishes but as disability-friendly as possible. That’s 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 work out a good suggestion that anyway never has a chance because it’s simply not your dream house.
I would really wish that you make a clear statement here, otherwise this will become 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 corner bungalow and take another look at kbt’s design.
Or be honest and say: we want a corner bungalow because we like it so much. It should be adapted as well as possible to the needs of our disabled son, please help us with that. That’s a clear statement and totally okay, but then it is no longer a house whose top priority is "disability-friendly."
