Cost explosion even before it really gets started

Thank you for your reply!

We have already taken a closer look at the new one several times; the information transfer is very slow, or in some cases not happening at all. Although we always ask very politely, by now a more direct tone would probably be appropriate. He also says at every meeting that he still has to check with companies whether more offers are coming. We have also obtained various offers with the specifications because we could already see that we would later have no comparison.

Last week we actually wanted to finalize the companies, but that just doesn’t work!

After the discount agreement, we also asked him at this appointment on Wednesday. He said that the 7 days refer to the receipt by the architect. Therefore, he sent us the invoice the next day by email (after 6 days then).

No, the offers are not one year old! Only that of the structural builder; all others were requested only after the building permit at the beginning of December.

How high was the [Rohbauangebot]?

But that's not the reason. The cost estimate is off. I talked to a few tradespeople. Renovating & remodeling is much more expensive than building new.

However, it was from an experienced architect. And he also signed the estimate again 2 weeks ago. We kept asking in the meantime whether the estimate was realistic. 8k euros for a bathroom seemed way too little to me as a layman. But the response was always that it would be fine like that.

What was the rough construction offer?

70k euros including demolition work in the old building and garage (without gate, of course).

How is everything supposed to fit into the bathroom? I find 8k extremely little.
