Construction costs are currently skyrocketing

What nonsense. Photovoltaics optimized for self-consumption are not oriented strictly to the south, but evenly to the east, south, and west to produce electricity as long as possible during the day. I can mount the modules on the house roof, garage, house roof, facade, balcony, fence, privacy screen, whatever. Where there's a will, there's a place for a photovoltaic system.

And you probably won't have shading in all directions. Just excuses

We wanted photovoltaics, got advice, and it turned out that due to the shading from the neighbor's trees and the neighboring buildings, it doesn’t yield enough for us. We would have preferred it differently as well. In the meantime, we have a carport, maybe it will work better there; we still have to deal with that. But there are also roofs that get shaded, and as an owner, you can’t always change that.

Honestly, I don’t understand your snotty tone and the accusation, and I think that’s not okay here – please communicate reasonably with me or don’t at all. I simply asked a question because I’m interested in the answer, not to be talked down to here.

The interesting question is whether we are seeing a peak in prices per sqm for new construction. What speaks for it, what against it? Any ideas?

I also tend towards sideways – it already seemed that the (extreme) prices of 2022 were still present in 2023. There was no more room upwards; downwards is difficult though. Presumably, the number of houses will now stay low over the years and people will hope for better interest rates. What definitely is happening – the "normal" houses in the 95 - 115 - 125 sqm category, which were previously completely out, are back and being actively advertised – sales argument: better small & mine than renting increasingly expensive.

Exactly. 120 sqm at 4% interest is now possible for anyone who could have built in 1990 as well. Just not any more and not for everyone anymore. As it was in the past.

Just to get back to the topic.
We have now commissioned our shell construction (solid + clinker), including the roof, equipment room, and carport. We are coming in at almost exactly €1,000/sqm, excluding earthworks.
We requested quotes from three shell builders and all were about the same except for around €500.
Each gave up to 5% discount on the final sum and all three are available immediately. At least for this trade, the urgency and availability have changed.
Whether this is expensive or not, I cannot judge. It at least matches the architect’s estimate.
So maybe this brings us back to the topic ….

To put this into context, a few more data points would be needed. Where? Total size or effort based on the floor plan? Energy efficiency level? Insulation included? Roof means “only” the roof truss? Windows included? Gross/net? Etc.
