ᐅ Demolition of a Prefabricated House – Who Has Experience with Tearing Down a House?

It seems the demolition companies around here don’t really know how to do dismantling; they all talked about a lot of sorting.

Sorry, I only half-finished that thought earlier: the other half of “this method doesn’t fit here” is that demolition companies are not the right contacts in this case.

Dismantling instead of demolition means: it’s better to take those who actually build houses “forward.” Practically speaking, that means carpenters, roofers, and drywall installers.

Or doing it yourself by arranging for containers, a digger operator working on hourly basis,

… I don’t really see that working here, as that would also be more like demolition.

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

The plans should show which manufacturer built the house. From the manufacturer and the year of construction, you can figure out the type of construction and wall structure. If the manufacturer still exists, they are the ideal partner for a renovation. If not, or if you want to completely dismantle (similar to tearing down a solid masonry house), then one of the carpentry companies currently offering house construction is the best partner. Then you let the drywall installer expose the wall assembly and the roofer handle the roof, and the carpenter can carefully dismantle the structure. Mindless breaking like in solid masonry demolition is not appropriate here.

Once the carpenter understands the construction, they can develop refurbishment proposals. With a clever architect, the renovation will come together nicely.

I do not expect contamination issues in the framing for the years mentioned, but rather in the cladding. Therefore, stripping back to the shell is the most cost-effective approach.

In this sense, I would recommend starting with a comparison: “planned building” versus “existing building.” In a second step, you can explore whether and with what compromises the desired house could be developed from the existing property.

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

To be clear: dismantling will not be cheap either. But it can more easily be turned into a renovation halfway through (or at least generate reusable materials). Ideally, the debris will “only” consist of bathroom and kitchen fixtures, wall cladding, and floor coverings in the best-case scenario.

@11ant,

your approach sounds so complicated and expensive that it immediately makes me think of a supposedly simple solution: extensive oxidation of the structure with the release of heat and light.

Various prefabricated house manufacturers have now also entered the “modernization” sector for their older existing buildings and have established dedicated departments for this purpose. If the manufacturer no longer exists (and has not been acquired), you can still rely on the tips from 11ant regarding carpenters for the dismantling process. With modern prefabricated houses, I no longer see the risk of having to sort a lot after demolition, provided you have chosen a supplier that builds with “healthy building” practices, avoiding excessive special waste and plastic sheeting, etc.

The fact is that a prefabricated house behaves very differently during the traditional destructive demolition process, especially when using heavy-duty wrecking methods, and therefore the routines involved are not what demolition crews usually expect: it breaks apart quite differently from masonry walls, and you also can’t just dump the debris into a crusher and spread it under the next highway being built. This procedure is so inconvenient for them that deterrent pricing is a logical outcome.

That also saves the effort and cost of rebuilding, since you can initially live in government-provided temporary housing with full board.

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

But seriously. If you don’t intend to make it an insurance fraud... a minor penalty for emissions and such, okay. But imprisonment?! I don’t think that would hold up in the end.

Section 306 of the Criminal Code does not apply in my opinion.

Section 306a might apply, but probably a lesser offense? No endangerment, no harm to others... it will likely remain difficult.

(Just theoretically)
