Hello everyone!
Thank you very much for the numerous messages. I will send pictures of the "bathroom" later. I would be happy if you could take another look then.
Regarding the laundry chute: For us, one of the best things you can plan in the house. I would rather do without the bathroom above than the chute. But of course, both would be optimal now!
Unfortunately, the chute opening in the attic, regarding the location, is a "small" planning error (albeit the only one). Unfortunately, the craftsmen were faster back then and we no longer had any influence on the location of the opening. Now it would be nice if, despite this planning error, we can still find a solution that is as elegant as possible.
I will get in touch later! Thank you all
