What material costs should be expected for interior construction?

Wait, have I actually been waiting three days for the answers to my questions???o_O

Hello everyone, please excuse me for not getting back to you sooner. In the past few days, we visited regional providers again, who build solidly, stone by stone. We were impressed by the verbal offers (written ones will follow). With hardly any significant longer completion time, up to 20 sqm more, and an attached solid garage, we have savings of up to 30,000 compared to the supraregional company from the model house park. This means that for now, the option of doing the work ourselves is off the table, as we simply don’t have the time, and I can fully understand the concerns expressed by friends regarding warranty.

We are now looking forward to the written offers and will surely decide on one of them then.

The decision for the bungalow was more or less taken out of our hands by the model house park, as we want to build in a village and a bungalow would more likely be approved there than an urban villa. The regional providers have actually said the opposite, since multi-story construction is more common locally. So maybe we will still achieve our original dream of an urban villa.

What surprised us now:
Regional builders are reluctant to build with air heat pumps but rely on gas combined with solar for hot water, as it is supposedly more cost-effective. Is that really the case?

Best regards
Sven

How do you come to your assumption in the last sentence? Just because the cheap gas/solar is advertised in the [Günstig-Lockangebot] doesn't mean that construction is done with this technology. If you want a Kfw 55 house, this technology is usually not sufficient anymore.

And you must not forget, even if the gas heating is cheaper in terms of price, you then also need a gas connection, which would have cost us over 2000.-.

First of all, I am happy for you that you found a seemingly more suitable offer ... then I am somewhat shocked by the naivety. You were surprised by the rate? What is your maximum rate? Please compare the service, not just the price. By the way, it is possible that construction is cheaper regionally than nationwide. With a €60K difference (€30K and 20 sqm), however, it will surely not be solely attributable to the regional factor...

First, wait and see how extensive the "cheap" offers are. Definitely compare and have them checked!

The gas issue is quite a thing – the gas system is apparently cheaper to purchase (and included in the house price), but the connection fee is added (not necessarily included in the house price, so you have to pay it separately).
Therefore -> Sentence 1.
