ᐅ Swedish Prefabricated Panel House / AB-Elementhus Renovation vs Demolition

Hello everyone,

We have purchased a Swedish prefabricated house from the company AB-Elementhus. It features a solid masonry ground floor, on top of which the prefabricated house is built.
Initially, the plan was to completely demolish the house and replace it with a new cross-laminated timber (CLT) structure of the same size.

While studying the building documents and permits for the AB-Elementhus house, I was positively surprised by the construction.
The wall assembly is (inside to outside) 2cm (0.8 inches) cross-laminated timber, 16cm (6 inches) compressed wood chips, 2cm (0.8 inches) cross-laminated timber, and 0.2mm (0.008 inches) stove-lacquered aluminum.
The planned layout of the new building could be realized within the existing structure, so I am now considering renovating and upgrading instead of demolishing (insulation, interior, windows, etc.).

Does anyone have experience with these houses?

Best regards,
Harv

I would advise you to do so only if the person you want to contact is online at the same time (you can then remove it within about ten minutes—otherwise your address will be quite publicly visible here).

Hello everyone, I am also the owner of a SEH - Swedish prefabricated house built in 1974.
We bought the house in 2017 and have done extensive modernization since then.
Unfortunately, we have no data or documents about the house from the previous owners. Does anyone have any information?
Regards
Tim

What would you like to know?
We completely renovated a house like this, stripping everything down to the foundation walls. Fortunately, we had plenty of documentation for it.

Hello everyone,
I am currently considering purchasing a prefabricated house built in 1975 by the company "Schwedische Elementhäuser GmbH."
I have already looked into prefabricated houses from that era and have often read about issues related to hazardous substances (asbestos, DDT, PCP, etc.) as well as unpleasant odors (e.g., caused by chlorinated anisoles).
Are these types of problems also common with this company, or has anyone here had any experience with their homes?
I would appreciate a brief response.

Best regards,
Dominik

I assume that the statement

This also concerns my case, an SEH (Schwedische Elementhäuser GmbH in Frankfurt am Main distributed and built AB Elementhus houses in Germany)

means that they are an importer of the complete shell, with the walls manufactured in Sweden. So you would likely need to look for information in Swedish about how neurotoxic wood preservatives might have been treated differently there—especially regarding whether and when they were banned compared to Germany.
In general, when replacing materials such as particle boards with older formulations with current ones, it should be considered that the residual toxicity of the old materials may now be below the limits set for the new materials.

No idea if I have already mentioned this:
I had a material analysis done—no abnormalities found.
It can be done for a relatively low cost at some laboratories if it gives you peace of mind.

In fact, particleboard is hardly used because the Swedes mainly relied on spruce cross-laminated timber back then. The infill is also spruce wood shavings.

The SEH has nothing to do with German prefabricated houses from that era.
You can find several posts about the construction both here in the thread and via Google. The approval plans for the elements are also available online for a few euros.
