City villa with hipped roof 140m²

Unfortunately, the house only looks appropriate in the little pictures. Replacing the chicken ladder with a realistic staircase would almost single-handedly blow the design. A bedroom is not just bed space, but also needs air volume to breathe during the night. The adjoining room does not work as such, and even less so with household functions. A "boiler" cannot be placed in the "workroom" that the electrician needs for his recoil.

Otherwise, the house is a wild mix of pompous and modest: children's room size, gallery, corner tub, guest shower, city villa outfit on one hand, but poorly planned living kitchen, lack of functional and storage rooms, single washbasin, and chicken ladder on the other.

There should be no guest bed in the study—so why the shower in the guest WC? I would fear that seasonal clothes in the study would be fiscally detrimental.

Thank you in advance for all the good ideas and suggestions!!!

Honestly, as already wrote, read up on the topic, air-to-air is nonsense if you don’t insulate to Passive House standard, you might as well burn banknotes directly for heat

Have you already talked about the heating load? Probably not.
As a guideline, air-to-air heat pumps are suitable for a heat demand under 10 watts/sqm. For KFW55 you're more likely at 30 watts/sqm.
Nothing set in stone but just as a guideline for a start. (At least that’s what I once researched)

I think with 5 sqm you would have the smallest utility/technical room I have seen here so far (well, I’m not an old hand).

Even if it should work on paper... you don’t want that.

No, our heating load has not been measured yet.
But we have already planned for support in the living room with 2x IR heating panels and 1x IR heating panel in the hallway. In the bathrooms, each one towel electric radiator.

I am happy to be proven wrong about the 5 sqm technical room. It does seem to be something unusual after all. Let’s see what my general contractor says.

We will take up the idea from to possibly use part of the guest bathroom for the technology and do without the shower.

The first thing I noticed is that the dining table is placed with the head side facing the bench. In my opinion, that just wastes space and looks illogical.

That’s right, it will of course be rotated 90° again.

The gallery on the upper floor is good – if it is closed off – as a storage room and “upstairs wardrobe”. The wardrobe space downstairs forces discipline: everyone just one jacket and one pair of shoes...

Very good idea!!!

The study is important if it is regularly used for value-adding activities. I would reserve part of the closet in the study for unused seasonal clothes.

We would implement it that way too, since two walls are completely free of windows. There is space here for another closet + bookcase.

Look for cabinet solutions for under the stairs. There are good ideas and storage space. You can store handbag, keychain, second jacket, and rubber boots there. It is inconvenient if the person working is disturbed just because the rain jacket is needed

The suggestion with the cabinet solution is of course very good. But it is certainly a custom-made piece? We have a staircase including which can be changed in material, color, and shape at the factory.

No, our heating load has not been measured yet. But we have already planned 2x IR heating panels in the living room and 1x IR heating panel in the hallway as support. In the bathrooms, each has an electric towel radiator.

Well, I'm really not a heating technology expert, but the logic doesn't make sense to me. The general contractor is planning a system designed for the values of a passive house. Now you can't reach those values and the heating capacity is not sufficient. Instead of opting for another system that can do that (gas, air-to-water heat pump, or geothermal + underfloor heating), he supplements the inadequate technology with additional heating installations that cost extra and consume even more electricity?

And otherwise I agree with , the design is unbalanced. Almost 19 sqm for children I find great and I can understand planning a 13 sqm study if you need it for work reasons, etc., but all of that doesn't work in 135 sqm. Especially not without a basement.

Take away 3 sqm from the children each and make a utility room upstairs, downstairs then only a half-timbered wall, eliminate the gallery, and furnish the open space anew. Maybe then it will work.

I would not commission that from the general contractor. The general contractor should not close the staircase side with drywall, but in the middle. Then the storage room is closed. Either the carpenter installs it or you install it yourselves. There are instructions on the internet.

is right. You have more electric auxiliary heaters than we do. How often are they supposed to run? When you shower or if you feel cold on the sofa in winter because a cold is coming on or permanently?

I have already been criticized here because of my inefficient heating system. I have a passive house and a more efficient system than you.
