ᐅ Renovating the Interior of a Bien Prefabricated House (Timber Frame Construction)

Hello everyone,

We are basically about to purchase a prefabricated Bien house from 1979. We have a building biology report, and the results are generally okay and not concerning. However, I would like to make the house as “healthy” as possible and have the following question:

Is it possible to renovate from the inside? Basically, removing the drywall, chipboard, and insulation. Then, treating the wooden studs with fleece or something similar to mostly block emissions (as far as I know, there are several options—the goal is to ensure that the wooden studs, which cannot be removed, emit as few harmful vapors as possible), installing new insulation, new chipboard, drywall, and done. Since there is currently no installation cavity, I would also want to add one at the same time (obviously before the drywall).

Is this generally possible? Are there any experiences, tips, or opinions?

Thanks and best regards!

The house is not exactly top-of-the-line, but it’s average quality. Each new chipboard panel off-gases more than the old formaldehyde compounds have yet to release. Do yourself a favor and skip the plasterboard strip nonsense. At best, that’s just a pointless exercise.
