Construction cost breakdown, specific offer: improvement suggestions?

Hi,

attached is our offer for the house.
Currently, we are at 300k for 140m2 with photovoltaics, storage, and heat pump.
Painting and flooring work are still to be added.

In your opinion, is there something we have forgotten or should consider?
Anything that doesn’t make sense in the offer?
It should be KFW 40+.

best regards

Felt familiar already. They had also inquired during the search for construction companies. These are all net prices now, right? €18,000 net for just under 5 kWp photovoltaic system and 5 kW storage is way too much. I would outsource that.

Otherwise, please pay attention to the price fixation period with ECO-Haus. I have the feeling (already experienced with several builders) that they artificially delay the time so that the price fixation period expires and then present you with a substantial increase. Important. Hire an external construction supervisor. You can also have bad luck with the internal site managers.

Prices include VAT. The problem is just that I don’t know how it works with the KFW 40+ if we outsource it. Then we would also need an energy consultant again, etc.

You need an energy consultant anyway. They are not allowed to be employed within the company either.

If you say way too much. How much is realistic and does it fit the dimensions like that?

I pay €1,100 gross per kWp for 13.29 kWp. The scaffold is used by the BU. The storage should now be below €1,000 / kW. I would guess around a maximum of €10,000 - 12,000 gross.
