Demolition of prefabricated house - Who has experience with demolishing houses?

The 306 not, it requires "foreign" things. But as a non-lawyer, I see quite good chances for 306a (houses are by definition buildings that serve as human dwellings. Nothing is said about "currently inhabited"). Possibly the public prosecutor can also make something out of the endangerment of the neighboring houses (if hopefully nothing really jumps over, otherwise the case is clear anyway).

Apart from the fact that the fire brigade is usually too fast and the operation usually does not solve the problem anyway.

Is one not allowed to controlled burn down their own property?

The approach isn’t that bad: offering the fire brigade to burn down the hut as a drill

It will probably be similar to old timber framing.

Wall and floor coverings, ceiling cladding, electrical cables, sanitary pipes removed, roof tiles, possibly filling material removed, wood is pulled out with the excavator and stacked separately. Construction debris, if present, is checked and determines the pollutant class, disposing of wood is expensive.

Only inquiries help. We searched for about a year. One company wanted over 100,000 euros in autumn 2015 for demolition in summer 2016, later gutted in winter, demolition in spring 2017 only 40,000. We had a lot of debris due to the demolition of the outbuildings.

How much deconstruction is required and what the disposal costs are depends on the federal state. Keep searching.

Hello dear ones,

thank you very much for all the answers. For us, it should be that the basement stays and we want to build new on top of it when the prefab house has been dismantled. I thought it would be expensive, but the numbers I am reading here are something else ... I am curious how high the first offers will be.

Many greetings

With us, it was supposed to be that the basement remains and we want to build new on top of it after the prefabricated house is dismantled.

I see (probably still as one of the few) a new trend there.

I thought it would be expensive, but the figures I am reading here are no joke...

As I said, I would benevolently consider whether the target house can develop from the existing house. There are slowly but increasingly carpentry businesses operating as "prefabricated house manufacturers." One of these could make a useful proposal.

Trend? I surprisingly often hear that people want to keep the basement. Sometimes I think it’s the false hope of saving significant money.

I talked to acquaintances (an architect) and relatives (building authority), and continuing to use the basement is only a minimal cost advantage (if any), because a basement from 1968 is simply not sufficiently insulated. (In our case, single-layer masonry made of sand-lime bricks sealed with bitumen sheets – nothing else). Insulating and renovating the basement (50% of which is living space due to the hillside location, but there is moisture in the basement and it is really in a dilapidated condition) doesn't bring much advantage compared to a new basement.
Now, the basement floor plan of about 16x10 meters is even larger than the desired new house. Keeping a basement larger than the actual house was strongly advised against.

For the demolition/dismantling offers still outstanding, I always ask for both options (with and without basement), but it looks like the whole thing is going away.

As I said, I would kindly check whether the target house could be developed from the current house. There are slowly but increasingly carpentry companies that act as "prefabricated house manufacturers." One of them could make a usable proposal.

Don’t take it personally, but that sounds like a DIY solution. I definitely don’t want to live in a prefab house from ’68. That thing is going away.
