Hello,
I have selected two home builders and requested quotes based on my custom specifications.
Offer 1 is from Heinz von Heiden, building a KfW 70 house with a ground source heat pump.
Offer 2 is from Viebrockhaus, building a KfW 40 Plus house.

The Viebrockhaus offer is exactly €43,000 more expensive than Heinz von Heiden. However, I would still receive subsidies of €15,000 from the KfW bank and an additional €2,000 from BAFA if I choose to build the KfW 40 Plus house. This leaves a net difference of €26,000.

What do you think? Is the KfW 40 Plus house worth the extra €26,000, or would you prefer to go with the KfW 70 house from Heinz von Heiden?

I look forward to your advice.

In my opinion, KfW 40+ is not worthwhile. You pay a lot more without it being cost-effective—unless you are already considering selling the house after 15 years. In that case, it might be worth thinking about. Otherwise, a KfW 40+ house can easily cost around 100,000 euros (about 110,000 US dollars) more than one built according to the Energy Saving Ordinance. Heat pumps, batteries, and other equipment also require maintenance. If they break down after 10 years (when the warranty ends), you are left with the costs.

What I believe is most worthwhile is KfW 55. You can also take advantage of bank loans and get a refund of at least 5,000 euros (about 5,500 US dollars).

I would avoid Heinz von Heiden. My in-laws built with them, and there was shoddy workmanship everywhere. Even I, as a layperson, could notice it.

Otherwise, it was a complete disaster.
How much would a Viebrockhaus built to KfW 70 standard cost?

Viebrockhaus does not build below 40+
