First floor plan single-family house 190m2

Hello,

we have already had several conversations with construction companies and have now arrived at a floor plan that we are quite satisfied with. However, we are having difficulties choosing the right construction company and are also not entirely sure if the floor plan is really optimal. In addition, we have not yet decided whether we want to build a prefabricated or a solid house.

House design
Who created the plan: do-it-yourself
What do you like most? Why?
All desired rooms were accommodated; little traffic areas; no dead space; utility room directly next to the bathroom on the upper floor
What do you not like? Why?
We do not like the layout of the bathroom very much because little daylight comes into the room
Price estimate according to architect/planner: approximately €450,000 - €500,000 according to various offers
Personal price limit for the house, including equipment: €500,000
Preferred heating technology: air-to-water heat pump + underfloor heating

If you have to do without, which details/extensions
-can you do without:
-can you not do without:
all rooms (especially the two offices) are important and must be retained

Why did the design turn out the way it is now?
A mix of many examples from various magazines, own ideas and drawings from various sellers/building advisors

What is the most important/basic question about the floor plan summarized in 130 characters?
- Do you notice fundamental problems with the floor plan? Do you have better ideas?
- Can the desired rooms be accommodated more efficiently on less space?
- How do we find the right construction company for our building project? We have already had many conversations and received offers but find it difficult to decide.
- Prefabricated house or solid house?

Thank you very much and best regards
Raphael

I think your budget will not be enough for 180 sqm. €2,700/sqm is rather the lower limit given the increased construction costs. Depending on where you are building.

Yes, I also believe that your budget for 180 sqm is too low. You want to avoid dead space (which I understand) but I think your floor plan suffers because of it. You have to walk through the kitchen to get to the living/dining room, right? And when you go to bed in the evening, you walk through the kitchen again? I find that strange. Also, upstairs I find it impractical that the laundry room can only be accessed through the bathroom.

Well: the kitchen seems to be located in a hallway. From there, a closed staircase, the [TK-Raum], the [WZ], the hallway, and the pantry lead off. That seems like quite a few pass-through rooms to me. Do you feel like cooking there?

The 180 sqm feel like 130 sqm because of the many interior walls and the impractical as well as uncomfortable room layout.

I have seen this several times now, that such large plans are made at a relatively young age. Two offices and two children's rooms, even though there isn't even a child yet? I would rather plan with just one office, because as long as there are no children who each need their own room, there is an office/guest room. But the questionnaire makes it clear that every room must be kept.

Are the garage and outdoor facilities included in the 500,000 or are those only for the house?
