There are three children's rooms plus a guest room/office. The rooms upstairs are not really that narrow and long – the left one measures 2.99, and if you actually raise the knee wall to a reasonable height, the room shortens and no longer feels so long. The support beams can remain visible from the ground floor. I now have a daylight bathroom, a daylight bedroom on the ground floor. I have a room at the back free as a utility room... I will now enlarge the living room a bit, enlarge the pantry there (under the stairs), and try to get daylight into the guest WC. Going well :)
Oh, I am more than curious. Wow. And sorry that I can't respond quite so quickly this weekend – the children keep me occupied! And I can't always speak directly with the structural engineer or engineer if there are lingering questions.
One more thing – which I hope I have explained clearly:
With the ground floor, it was more about getting a bathroom with a window than the guest WC. But regarding the bathroom, I absolutely understand if it simply isn't possible. There's no need to keep trying endlessly – if anyone present has a gut feeling that something like that won't work... then I already place a lot of trust in that!
Upstairs, the three children's rooms and a bathroom with a window are "desired." A possible office/guest room would be great but is not the highest priority. The lighting through a double casement window upstairs is not entirely clear to me (for example if a continuous dormer is used on the south side to light the rooms), but I will be surprised and am already thinking about it...
I can't write it constantly, but the support here is really fantastic. For months I/we have been moving the rooms from left to right and it never quite felt right. Not entirely bad, but somehow not harmonious. It was simply necessary to clear my head and sweep everything off the table so far. That has already been more than successful – thank you very much!
