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

Demolition companies around here probably don’t really master deconstruction, they all talked about lots of sorting.

Sorry, I only half wrote the thought earlier: the other half of "this method doesn’t fit here" is that demolition companies are therefore also the wrong contacts.

Deconstruction instead of demolition means: it’s better here to take those who also "build houses forward." Practically speaking: carpenters, roofers, and drywall installers.

Or self-performance in the form of procuring containers, an excavator operator working on a time and material basis,

... I rather don’t see that here, because that would also be more demolition.

Well, I only have the measured plans, but nothing that allows conclusions about the house’s construction.

From the plans it will be recognizable which manufacturer built the house. From manufacturer and year, one can find out how the construction and wall structure were. If the manufacturer still exists, they are the ideal partner for a renovation. If they no longer exist or you want to completely deconstruct (analogous to solid construction = "tear down"), then one of the carpentry companies currently offering house construction is the best partner. Then let the drywall installer expose the wall structure and the roofer expose the roof, and the carpenter can professionally dismantle the construction. Dumb smashing like in solid building demolition is not advisable here.

As soon as the carpenter has an overview of the construction, he can develop renovation proposals. With a clever architect, the renovation will be a smooth process.

I don’t expect contaminations in the "timber framework" for the mentioned construction years, but rather in the paneling. Removing it back to the shell is therefore the most cost-effective way.

Therefore, I would advise starting with a comparison: "building target" versus "building actual." And in a second step then pursue the question of if and with which compromises the desired house could be developed from the existing house.

Susi_90 and DonRolando want to continue using the basements anyway, I "hope" (?)

To be clear: deconstruction will not be cheap either. But it can be better turned halfway into a renovation (or at least generate reusable material). At best, the rubble will later "only" consist of bathroom and kitchen stuff, wall paneling, and floor coverings.

your approach sounds so complicated and expensive that I immediately think of a supposedly simple solution: A comprehensive oxidation of the structure with the release of heat and light.

Various prefabricated house providers have now also discovered the business sector "modernization" for their old existing buildings and have established their own departments for it. If the provider of course no longer exists (and has not been taken over), you can still rely on the tips from 11ant regarding the carpenters for the dismantling. With modern prefabricated houses, I also no longer see the risk of having to sort a lot after demolition, provided you have chosen a provider for "healthy construction" without much special waste and foil, etc.

It is simply the case that a prefabricated house behaves completely differently during the classic destructive demolition with lead balls and therefore is not a world for demolition crews in terms of routines: it "shatters" quite differently than stone walls, and you also cannot dump the rubble into a stone crusher and spread it under the next highway to be built. This is so unpleasant for them in terms of procedure that deterrent prices are a logical consequence.

That then also saves the work and costs for reconstruction, because you can first live in a government-provided accommodation with full board

Is it not allowed to controlled burn down your own property?

But seriously. If you don't intend to construct an insurance fraud from it... a little penalty because of emissions and such, okay. But imprisonment?! I don't think that will stand in the end.

Par. 306 StGB does not apply in my opinion at least.

Par. 306a probably applies, but then a less severe case? No endangerment, no harm to others... it will probably remain difficult.

(So purely theoretical)
