First offer, 157m2 with basement, KFW 70, garage

QUOTE]Are you sure that you are not comparing apples to oranges? Have you taken the time to carefully read the building descriptions and really compare them? With exactly the same equipment, the prices should also be roughly the same. I don’t believe in the same starting conditions with a difference of €100,000.[/QUOTE]

I do consider myself able to compare offers. Inquiry/offer processes make up about 50% of my professional daily routine.

Hello everyone, first of all thanks for your willingness to participate. I will try to answer all questions...


The plan shows floor-to-ceiling windows, but I also think that the French balcony should not cost extra?


We explicitly said that a Poroton stone should be used. The recommendation here was the t7 with filler, but I believe not mineral wool, rather perlite.


The offer is not from Town & Country as written above.
Until now, I was actually always under the impression that triple glazing is standard. I didn’t know that for the floor sliding staircase yet, but when I compare prices, I think it could be cheaper, although the offer already includes chipboard covering at that point, although I don’t know if those shouldn’t rather be OSB boards? I also find the extra cost for the underfloor heating steep, but it is in every room, right? The basement is a standard basement, as I just learned today (from the geologist who just completed the soil report), we at least do not need a white tank/waterproof basement, more details when I have the report myself. I didn’t think of a lifting system for the washing machine at all, but I think that is a small part. Surely many small parts will still come, which add up. Regarding your question about additional construction costs, these are on a different invoice, in the so-called budgeting. These are:

Outdoor facilities 10,000.00€

Kitchen 10,000.00€

Additional construction costs:

Supply of compactable material 4,000.00€
Surveying 2,000.00€
Construction power / water connection 1,000€
Authority fees 1,500.00€
Connections to utility providers 4,500.00€
2 inspection shafts SW+RW including civil engineering and connection at the building 6,500.00
Civil engineering / trench for utility providers up to the technical room
Earthworks: store topsoil sideways 7,000.00€
Transport 200 cbm of excavation material to landfill including landfill fees 5,500.00€
Cistern 4,500.00€

So the house including additional construction costs etc. is offered at 395,000.00€

Regarding the offers, this is one of several, more will follow. It is only one offer based on a draft, no negotiation or anything else has taken place here. I just want to know if it seems realistic, what one should watch out for...

Thanks so far
Regards G0bi

..., however, at that point in the offer chipboard flooring has already been taken into account, although I don't know if it shouldn't rather be OSB boards?

Here is another hint: You should have the OSB boards (or whatever) brought up to the attic already, but not laid out yet. During the first year, your house will still be drying out. If you close the attic (i.e., lay the boards), you risk mold formation. However, you can and should already have the boards brought up (the carpenters lift them directly in with the crane) – you surely don't want to drag such boards up via the retractable ladder in the floor.
