Construction costs are currently skyrocketing

We are right in the middle of the "climate catastrophe", (...)

That is indeed the case. Five of the warmest summers since the beginning of weather records have occurred in the last 10 years. And you have to go back quite a way to remember a really cold winter. It was 2010/11.... The few days of frost in December 2022 were a joke and not a "winter".

So, we have winter on the construction site. On Monday, the driveway was supposed to be dug up with the 3t mini excavator so that electricity and internet can be laid. The gravel was frozen 40cm deep and had to be broken up.

What standard are you actually building? I assume 40+ and the house as small as possible to contribute your part? ;)

The brother had frozen ground on Monday and therefore believes that everything is fine with the climate. :D

I think it actually only works for condominiums. And that is certainly intentional...

Didn’t one of the members of the Gummibärchen gang even say in an interview that the concept of a single-family house is not compatible with climate protection and therefore not politically desired at all? Since the portal was shut right in front of our noses a week before submitting the 40+ application, I trust them about as far as I can throw elephants. Whoever nowadays is actually dependent on funding - as harsh as that sounds, in my opinion - unfortunately no longer belongs to the group of people who should consider building a new house. In the past, these were often just free-rider effects with phantom granny flats, etc. I still get a bit emotional about the topic of funding :-D

Does anyone currently have information on the topic of tiles? For example, what is the allowable additional cost for laying rectified tiles? The joint should be 2mm

A colleague currently has an issue there

Why should one pay an extra charge for that? Rectified tiles are actually more desired by the tiler.
