Rot-damaged timber facade

[Assen87]

I am interested in purchasing a vacation home where part of the timber facade is damaged by rot. The picture shows one of the worst attacks and there are a total of 5-10 similar damages in corners and joints. The cause of the damage is, as I understand it, that the facade was repainted with plastic paint over 10 years ago.

My considerations for solving the damage

• Have a company scrape off all the paint
• Scrape/chop/saw away all rotten timber
• Patch and repair to make it reasonably sealed
• Cover the timber facade with a wind barrier, air gap, and panel

Is there a risk that the damage under the paint is so severe that the house must be demolished? I don't have much experience with timber houses, so I welcome all thoughts, ideas, and tips.

The wood has been rained on, causing it to absorb moisture and not dry out properly. It's probably not too much of a concern for holding up, just remove what is rotten, then put battens and wind barrier with new paneling on the outside. Possibly cut away the corners, leaving about 5 cm. It's important that the bottom ones are okay. You can do this yourself without paying anyone for it.
