If you had to give up anything, which details or additions
- You could give up: basement, but then larger footprint
- You cannot give up: 2 workrooms

Why is the design the way it is now?
Standard design from a planner? The basic dimensions are based on the Maxime 610 model by Viebrockhaus, with additional influences

What is the most important / fundamental question about the floor plan, summarized in 130 characters?
We already like the floor plan quite a bit. The walk-in closet upstairs is still not ideal. Possibly the entrance could be through the bedroom, which would create more space in the closet.
Windows in the basement have not yet been included in the plan but are, of course, intended.
We would just like to hear some opinions on this since we are completely new to building.

Many amateur planners hope for a decisive first step from a blank page by using some key data or basic features of a model they like as a starting point. However, this "help" comes with a cost: it limits your thinking more than you might expect. It would be even more mistaken to assume that the basic features of a model with the same exterior dimensions roughly translate to the same price range. Once you move into the visual realm, it becomes difficult for inexperienced planners to stay abstract—which is actually still necessary during the preliminary design phase.

In my opinion, a better way to start planning is to first list the rooms and their approximate sizes, then in the next step divide the list into what goes on the ground floor and what belongs on the upper floor. If both floors have roughly the same area, this suggests a straight-walled upper floor (sometimes called a "town villa"). If the upper floor is about half the size of the ground floor, this points toward a one-and-a-half-story house.

This step is often skipped if you start from a model you like without comparing it to your own needs (for example, the original model might not have a bathroom for children).

These are rough construction dimensions. This results in an effective shower width of around 74cm (29 inches) in the kids' bathroom. With typical building tolerances, this can quickly shrink to about 70cm (28 inches). This tends to be rather uncomfortable as the child grows into a tall teenager.

Of course I do, otherwise I wouldn’t be here.
#14 explains it well enough that it needs improvement!

Take a look, at https://www.hausbau-forum.de/threads/Einfamilienhaus-owl-ca-150qm-mit-ostgarten.33419/page-14#post-378608 your Maxime has also been interpreted (the entrance and staircase are arranged differently, but otherwise you should recognize the floor plan).

I have taken some of your suggestions into account.
As a result, the staircase needs to be rearranged, which creates a new layout on the upper floor.

What do you think about this?

PS: The upper floor plan is almost exactly the same as a variant found in the Viebrockhaus catalog.

Floor plan: Open ground floor with kitchen, dining/living area, guest room, pantry, entrance, guest toilet.


Upper floor plan: Study, children’s room, bedroom, walk-in closet, master bathroom, gallery.
