Single-family house floor plan, feedback

Together with

We generally like the ground floor, but we would swap the office and kitchen + living and dining areas

and the large unused hallway on the ground floor, simply swapping is not an option, in my opinion a new plan is required.

I consider this to be a two-story building ... ah .. you mean all the increasingly expensive corners on the ground floor, which then all require flat roofs, making it a one-story building.

Yes, exactly. I think that was calculated by the draftsman that way.

Unfortunately, the uploaded pictures are so poor in resolution that you can hardly decipher the numbers.

I will try to upload better pictures shortly.

But somehow the ground floor's footprint looks very inefficiently used.

Do you have any suggestions on how to use the spaces better?

Price .. it's over 200 sqm, brick-clad, lots of corners, so I also consider 550 kEuro for everything to be too low. Are there actually any suitable offers available?

No, so far only the calculation. We will only obtain offers once we are (almost) finished and satisfied with the floor plan.

Bathroom should be accessible from the hallway // windows not directly aligned vertically

The master bathroom accessible from the hallway? Why?

And which window fronts bother you? What do you mean by directly aligned vertically? There are also windows of different sizes.

Other suggestions are not that easy, this is a development process after all. For example, I would also find a site plan with the plot marked interesting.

At first glance, without doing the math with a sharp pencil, this is a single-story building.

Sorry, I don’t want to confuse anyone: of course, I meant a two-story building! It’s obvious anyway. I just made a typo.

however, this is only a suggested lightweight wall, which would only be erected after all the technology has been installed.

You can’t install technology later if you often need access to it. That doesn’t work.

Thus, the technology area would be larger in this case and the utility room correspondingly smaller, which shouldn’t be a problem,

This results in a different floor plan in this area. In principle, you have to completely paint the small area and turn the utility room into a technology room—also to avoid giving false hopes about usage. If you like it classic, that’s how it is. Then you get designs with a hallway in the middle and a windbreak at the front. But it also means you get a completely interior corridor. Certainly, you could relocate the staircase to the outside to provide stairwell lighting, but that’s no longer practical at a certain size because the paths become too long. If you want larger children’s rooms, you’d have to omit the hallway or build (even) bigger. I checked again: Lower Saxony. Definitely a two-story building. The garage is separate. Regarding the design: for Lower Saxony, affordable €3000/sqm for this object. But it’s not a Viebrockhaus, more likely a TM house. Without garage. Without kitchen. Without additional construction costs. Without outdoor area. Anyone who orders a country house gets one at the corresponding price.

May I ask for the [Landkreis]?

Where would you see the budget? The calculation already includes kitchen, outdoor area, photovoltaic system, and a 10k buffer.
Our future neighbors even found the estimated 550k very high...

For the house? 600k (+x) for the house, 50k incidental construction costs, 35k for the garage, terrace + driveway + outdoor facilities from 30k depending on wishes.

In total, I would take 750k as a base to have some room.

Could be a bit cheaper if you live in Ni at the AdW.

Where does my estimate come from? Professional experience.
