Cost estimation for demolition and new construction

If it helps you to classify: We are currently demolishing a roughly 250 sqm large, partially basement house from the 1920s. The somewhat serious offers started at about 30K euros for gutting, demolition, and disposal, the highest was about 42K euros. A large part of that (about 10K) are disposal costs. The house is uninsulated and due to the age of the house, almost no hazardous materials like asbestos are installed. In a house from the 60s, the probability that asbestos is installed is presumably significantly higher, which could then also result in significantly higher disposal costs.

Thanks, that is actually helpful. Asbestos is a good keyword. I have to find out when it was regularly used.

It is faced with bricks, which is somewhat more expensive.

This, not least, speaks against the fear of a cheap construction.

Unfortunately, I can't say much more about the construction type. Measuring the wall thickness in the plan with a ruler is probably a bit too inaccurate?

Yes. It will probably be about 40 cm faced with bricks: 25 cm bricks still in the old Reich format (until the 1950s), presumably "monolithic" built up with the facing bricks. That would then be 38 cm.

Yes. The brick facing will probably be about 40 cm: 25 cm bricks still in the old Reich format (until the 1950s), presumably built "monolithically" up with the facing bricks. That would then be 38 cm.

Or also 24 cm pumice blocks and 12 cm hollow bricks ("red facing bricks") placed directly next to each other. That's how my new house was built with a 36.5 cm wall (from the mid-60s). Either way, definitely not bad for the year of construction.

Brief update: The court date is scheduled for now. Whether due to Corona or because the debtor has reached an agreement with the bank, I have not been able to find out so far. We’ll see.

It is also possible that someone secured the house before the appointment. Such things are always possible.

I am only reading the topic now because of your current post, but of course I have read the initial post and am completely puzzled:
I can understand that you occasionally keep an eye on houses etc. in your surroundings.
But are you seriously planning to possibly tear down the house you have always admired? Even though you are happy with your current living situation?
Maybe one should just let fate rest? In the end, you will “only” be changing your living situation and not necessarily improving it... possibly realistically face the demolition of the crush/dream, realizing that one should sometimes let go of dreams/admiration because they are mostly seen through rose-colored and unrealistic glasses (it's kind of like teenagers falling for adults or singers, actors).

So, if I were you, I would think about whether it’s all worth it and whether you will get what you wanted or whether you still want now what you wanted before.

Now we have found out by chance that “the house” I have admired for about 6 years is going to be auctioned off.

I am completely “out” on the topic of new build costs.

About 7 years ago we built an end-terrace house and are happy with it, apart from the usual minor issues.
