Unfortunately, I couldn’t really find much through the search.. O.o
We were actually leaning towards a solid construction house (massive house).. Yesterday, we had a consultation about a Liv...... house, which is a prefabricated house..
We hadn’t really looked into prefabricated houses before, but wanted to hear what he had to say.
A few interesting points came up, for example, water damage.. Since the area is still classified as a flood zone (there was a major flood here in ’94 and never again since then, plus a retention basin is currently being built, so the flood risk is being downgraded), this topic is not insignificant..
The consultant said: If water damage occurs, you can "simply" remove the affected element, let it dry, and close it up again, and you should be fine.. (I don’t really agree with this, but I’m open to being convinced otherwise), which wouldn’t be the case with a solid construction house..
Additionally, there wouldn’t be geothermal or air-to-water heat pumps with underfloor heating, but rather a so-called "comfort climate heating" system, meaning everything is done through air via the ventilation system (air is heated/cooled using a heat exchanger and distributed into the respective rooms).
Has anyone had experience with this? I know it’s a comparison between apples and oranges.
Thanks =)
Regards
Steven

These "air-only" heating systems often receive quite negative feedback in experience reports, either regarding living comfort or costs, because it seems quite difficult to satisfy both at the same time. However, as always, there are different opinions on this.
Regarding water damage, I tend to think that a wooden (timber) frame construction is more vulnerable than a monolithic building, but I might be wrong?... no idea

You are correct in both cases.
Water damage in wood is a serious issue. Replacing the wall is necessary; it’s clear the person is not very knowledgeable, the representative...
Air heating systems—he should sell those in Greece; here, despite climate change, heating is still needed.

Timber frame construction in a flood-prone area?
I would be worried.
In my opinion, the timber frame (solid wood element) can dry out just as well as masonry. But the insulation inside and the utility lines—that’s where masonry is, in my view, the better choice. Even the interior plaster is only damaged up to the level the water reached. With timber framing, the drywall is ruined even at just 10cm (4 inches) of water height.
Heating via air distribution instead of underfloor heating works in a passive house. I would choose it anytime again. But in a non-passive house, I would stay away from it. If it’s a pure air-to-air heat pump, operational costs will become quite high. Even in our passive house, a pure air-to-air heat pump is not installed. We use a hybrid system.

The forum search here is indeed not great – but you should still be able to find plenty of threads illustrating that you’re completely off track with your "prefabricated vs. solid construction" idea: even aerated concrete blocks and other solid building materials can be assembled into wall panels in the factory and then lifted onto your site by crane. So, masonry walls and prefabricated construction are by no means mutually exclusive.

There is an older discussion thread here about the "comfort climate heating" system from another prefab home provider. The most important points about the heating system are already covered there. As is often the case with some representatives, a lot of hot air is blown...
Just try searching for:
