ᐅ Replastering or resurfacing walls (with photos)

Hello everyone,

As of today, we were finally able to start work on our half-timbered house from 1890. First, we removed the old wooden slats from the walls and uncovered the following:

Now we are wondering what would be the best (and most cost-effective) way to re-cover the walls? Ideally, we would like to use drywall (gypsum board), but I have heard that this is not recommended for half-timbered houses due to the risk of mold.

The house is not directly exposed on the outside, as it is covered with fiber cement panels (Eternit), so the timber frame is protected from direct rainwater.

It would be great if you could share some advice.

Best regards,
Dirk

Unfortunately, I can't contribute on this topic, but is the roof really as "wavy" as it appears in the photo?

Should the facade remain?

What is the budget? What work needs to be done?
Everything is still possible, from plastering and clay plaster to drywall, wood fiber interior insulation, and wall heating.

Wow, you really took on quite a project there.

If you already have the walls open, I would first have the wood inspected to see if it is still in good condition everywhere.
A huge project both financially and in terms of time commitment.
Doing it right, demolition and rebuilding is probably cheaper. But I think it's great when houses like these are preserved.

Phew, I always admire people who dare to take on something like this. However, your post including the question (+ affordable) leaves me a bit puzzled. Has a professional looked at this?

Before starting, a thorough structural assessment should be carried out urgently; otherwise, you might end up wasting a lot of money.
