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

Hello

We are currently planning the renovation of our house. It has a solid basement with a prefabricated house from around 1970 built on top. Has anyone ever demolished a prefabricated house like this and have experience with it?

Best regards

I am facing a similar situation (built in 1968, but also a solid basement with a prefabricated house on top) and have already contacted several demolition companies.

Surprisingly, many rejected the job outright because they do not want to dispose of prefabricated houses (too much sorting of hazardous waste involved, leaving them with hardly any profit).

The cheapest offer was then $40,000 (including VAT), whereas a solid house could be disposed of for significantly less.

So, what will it be: renovation or demolition?

With the approach used for a traditional frameless house (breaking it with a sledgehammer), it has to look like that because this method is not suitable here.

Prefabricated houses are usually dismantled rather than demolished. Unfortunately, their construction is less standardized, so having the building plans is even more important.

Ideally, you know all the plans and the manufacturer still exists.

Maybe a company can be found if the project is to be commissioned for next year? It might make sense to open a small section of a wall from the inside to understand what to expect.

Or do it yourself by sourcing containers, hiring an excavator operator on a time-and-materials basis, and then sacrificing two weeks of vacation?

Man, what prices. On Monday, someone is demolishing our old office building from the late 1960s, with an asbestos Eternit roof. The wood is definitely soaked in Xylamon. His price is 12. Karsten

The local demolition companies here apparently don’t have expertise in dismantling; they all talked about sorting a lot. Regardless, I’ve always heard that it is significantly more expensive than with solid construction. (Just breaking it down and hauling it away is simply less time-consuming.)

Well, I only have the dimensioned plans, but nothing that provides insight into the house’s construction.
