I have a 1.5-story villa from the year 1900 with a log timber frame on the lower floor and posts on the upper floor. Currently, there is no water in the house, so I will demolish the old porch and build a new two-story one where practically all the water facilities will be; a bathroom on each floor. The kitchen sink will be just on the other side of the interior wall in the old house, so that's all I need for plumbing in the old building. The house is built on a crawl space.
I have read in several places that one should make a "rörlig fog" (flexible joint) between the old house and the extension but have not received an explanation on how this is accomplished. It still feels logical that the new ridge beam is securely attached to the old house, as well as the roof boards. It also feels quite natural to be allowed to nail the new exterior wall to the old one.
Grateful if anyone can share experiences and literature recommendations.
...and how important is it to choose the same foundation, i.e., a crawl space for the extension? I have also found writers who do not insist on this. Since I plan to install electric underfloor heating and tiles in the lower floor's bathroom, it seems on the one hand simpler and cheaper to lay a slab on the ground.

If you're going to apply DILATIONSFOG, I don't think there's anything special about the execution.
You place a thin insulation board between the old and new construction at each joint where needed. The insulation is primarily for preventing cold drafts and retaining heat...
If you make the new construction standalone, you can handle the joint elegantly, and you can conceal the seal with something like a transition strip, door frame, or another suitable solution.
It's not as difficult as it sounds; it becomes apparent as you build. Just remember to have a standalone new construction ---
