ᐅ Which Building Materials Are Suitable for a Lakeside House

We are planning to build a detached house near a lake. Although the flood risk is low, I am wondering which building material (wood or solid/masonry construction) is best suited and most resistant in case of flooding. I have received different opinions from various suppliers and am quite uncertain. I hope to get a neutral assessment here. Thank you!

Wood is best, as it can float well in case of flooding.

And it’s best to install the screed as a floating floor 😎

I think it doesn’t really matter. In my opinion, solid construction still has some advantages when the drying company arrives. Have you considered possibly raising the house? I’m not familiar with the specific conditions.

First, get detailed information from the relevant authority about this lake.
Does it have a natural inlet and outlet? What were the highest water levels over the past decades?

I would try to find out if, from a geological perspective, the lake actually poses a risk of swelling this much. If it lies in a basin and has a natural overflow with basically unlimited drainage capacity, you don’t need to consider this risk as a central factor in your planning.
Our city has published an online map that color-codes flood hazard areas and highlights them. This clearly shows which areas could be flooded by the local river. We ourselves are 50m (165 feet) from such an area, so we have to realistically expect that it might happen here someday. While not on the scale of the Ahr Valley, in 1999, just 20m (65 feet) from our front door, everything was flooded as well.

You can only really answer this question properly yourself after thoroughly examining the local conditions and then discussing them with an expert.

Getting a spot by the lake is already quite exclusive, in my opinion.
I would love to have such a view from my home, or at least a nearby walking path.
If you have to expect flooding, that’s different from situations where it’s unlikely to happen. But of course, there are many levels in between. ... and: it’s better to prepare for more trouble in the future rather than less.
Stone or wood?
I believe – as an experienced craftsman and construction novice – both have their strengths and weaknesses. Well-made wood is resilient, while stone may remain more stable in its place?
Above all – from what I’ve observed after many disasters I’ve seen in news reports and on TV – it’s not only the water itself that is the danger, but also heavy objects like trees, cars, or even other houses, which can become hazards.

I read about such opportunities with envy but am also glad that – at least in this case – I’m not exposed to that kind of risk.

Thinking about it, I realize that nowadays all houses are insulated in some way. This material should be able to resist water … or be easy to replace …
