Risk of water damage in wood stud/prefabricated construction?

Regarding flooding, I can say the following:

Poroton filled with insulation and Styrofoam on the outside is not exactly optimal for drying. Often, the Styrofoam has to be removed and it takes a while until the perlite or mineral wool between the brick cells is dry again. The same applies to double-shell wall construction with facing brickwork.

It can even happen that a prefabricated house dries faster... (depending on the wall construction... there are also prefabricated houses that, despite the "XTreme Ultra Thermo Super Mega Passive Wall," have Styrofoam attached to achieve Kfw40)

One should also consider that a waterlogged load-bearing component loses its load-bearing capacity! (How is it with wood?)

In general, moisture is also found in or under the slab after flooding...

A wall construction with, for example, sand-lime brick or aerated concrete or ... is easier to dry there (i.e. without ETICS or multilayer construction)

As a rule, these houses are significantly less sensitive to water. The supporting basic structure could only be damaged if it stands in water for an extended period. The houses are not set up without reason even in pouring rain, where water then runs through the whole place. In the unlikely scenario that a pipe in the wall bursts, a new one will probably have to be installed. However, this is much less problematic than in a solid house. I consider it to be of little purpose to choose a house based on such a criterion. Then one could also concern themselves with earthquakes and plane crashes.

Thank you again for the answers!

The result of this question is not the main criterion for choosing the construction method. We are currently leaning towards a prefabricated house and it reassures us that a prefabricated house dries relatively quickly. We do not want to safeguard against all eventualities, but I consider water damage by far less far-fetched than a plane crash.

In the unlikely scenario that a pipe bursts inside the wall, one would probably have to replace it. However, that is much less problematic than in a solid house.
I consider it rather unproductive to choose a house based on such a criterion. Then you might as well worry about earthquakes and plane crashes.

When I look at the wall constructions from various manufacturers, I notice many layers in the walls that will surely swell if they get wet and deform.
Am I mistaken? I can hardly imagine that nothing swells.

Hello JayBeOh..

we also own a timber frame house.. and I can assure you that as long as you don’t completely flood your house inside and outside, there should be no problems.

Of course, if you want to build in places that are permanently underwater during rainfall, you won’t enjoy the house.. neither timber construction nor stone.
I then recommend a houseboat.

Any statements like: "Wooden house is not weather/moisture resistant" are a trick by stone construction companies,
who (rightly) fear losing their customers!

And on the topic of "dry"....
Our house is so tight and insulated that the wet screed took a whole 3 days to dry without any construction heaters!
(All that was running were 2x 15 euro bathroom heaters)

The same with putty, primer, and wall painting work.... The walls dry inside the house so incredibly fast, it’s just amazing.

Hello,

since we are in the preliminary phase of purchasing/building a new house, we are currently weighing the different construction methods against each other. In this context, the question arose whether a prefabricated house made with timber frame construction is more susceptible to water damage or even flooding than a solid brick house.

Why should it be more susceptible, assuming you hire a reputable provider? Water damage causes a lot of harm in any system; even concrete does not come through entirely unscathed.

Your decision should therefore not get stuck on this point
