After we moved in 3 months ago, I would like to take the chance once again to thank you all for the many comments.
I would also like to address some of your remarks that we have considered (or not) and how we stand on them now.
In the vestibule there is a clear room height of 2.21. I imagine that to be very oppressive, especially with the small area. However, this ceiling height hopefully only refers to the vestibule?
This was one of the most important comments at all. We would not have noticed that. We have now removed the reinforced concrete ceiling in the vestibule. The ceiling height is now almost 3.6m.
Bedroom... But with 3.3x, there is about 60cm left on each side. That might be almost too narrow for sitting on the bed.
I also would not bother with the stairs. They would have to be way too steep and narrow with the small stairwell.
Also a great hint. We have now made the house longer and have almost 90 cm of space on both sides next to the bed.
We did not change the stairs anymore. They are very easy to walk on and are neither narrow nor steep.
About the pantry:
The first thing I would do is paint the pantry, which is anyway not usable because it is not deep enough.
Instead, plan a properly large kitchen where EVERYTHING can fit (keyword tall cabinets)
The pantry remained and is 1.25 m wide. The room is worth its weight in gold. I cannot understand the criticism of the pantry and the dimensioning. We placed the freezer at the front side and filled the entire side with shelves. The pantry is in no way too narrow or difficult to use.
About the cloakroom:
Then I would not separate it as a separate room. It is annoying to squeeze into a 2x2 room where there are also cabinets. I would completely remove the wall, maybe move the door to the garage a bit down, and then place a nice big cloakroom on the wall to the garage.
Your vestibule is just hard to furnish, I see hardly any possibilities for a cloakroom, or is the storage room supposed to serve this purpose?
A battlefield behind a door remains a battlefield. Then the Zalando delivery person admires your stylish clean entrance, but for everyone allowed to open the door, the battlefield behind remains the same. Instead of a door, I would rather introduce a tidiness-oriented allowance system there.
Shelves alone produce zero order; that has to come from the users.
We use the room behind the vestibule as a cloakroom and are very happy that we left it that way. We furnished the room with Ikea Pax and thereby were able to keep the battlefield under control.
