House design
Who created the plan: planner from a construction company together with architect
What do you particularly like? Why? - terrace accessible from kitchen and living/dining room, lots of space/storage
What do you not like? Why? - children's rooms too differently sized
Price estimate according to architect/planner: not yet calculated
Personal price limit for the house, including equipment: 300,000
Preferred heating technology: gas with solar thermal

If you have to do without, which details/extensions
-can you do without:
-can you not do without:

Why has the design become what it is now? E.g.
Standard design by the planner? - first draft made on a whim according to our specifications, already corrected once
Corresponding/which wishes were implemented by the architect? - except for the children's rooms, everything

What makes it particularly good or bad in your eyes? - In my opinion a successful design, but still needs improvement. We would move one or the other wall, especially on the upper floor

What is the fundamental question about the floor plan summarized in 130 characters?

I would like to hear opinions on our design to weigh strengths and weaknesses and possibly avoid fundamental mistakes that we may simply have not considered.

Oops, I marked it on the development plan.

Is your terrace facing NE?

Otherwise, I find it good at first glance. The bathroom on the upper floor could still be changed quite a bit.
How high is the [KS]?

I can't tell the cardinal direction from the development plan right now. How is the house oriented?

At first glance, I find two separate garages just for cars excessive. Unless one side is supposed to become a workshop or something similar, I would remove the dividing wall. I would probably remove it even then.

Somehow, the whole thing gives me an uncomfortable impression because of the dominance of the cars. Living room and kitchen are very separated. A lot of space is taken up by the toilet and airlock, although it's unclear why a shower is needed downstairs. Besides that, why not enter directly from the garage into the hallway and rather create an extra room as storage or something similar?

Upstairs, I would shorten the hallway and access the bedroom through the dressing room. This would also optimize the children's room at the same time. I have to say, however, that I find such narrow dressing rooms nonsense – but apparently, they are in now.

I would make the door from the kitchen to the living room larger, as a double door.
The entrance area or hallway is too dark. I would plan larger windows next to the door here, if necessary also in front of the stairs.

I also thought about the door upstairs. There is actually real potential with the children [emoji106]

Think about a chute for the laundry!

300,000€... quite ambitious for the size including 2 garages and a basement.
