ᐅ House Behind a Levee – What Should Be Considered?

After several years of searching, we have finally found our dream plot. The problem is that it is located just behind a levee on the Danube River (disregarding the old buildings on it, but that’s another story :p). From the start, we ruled out building a basement because the groundwater is also not far below.

However, if we still decide to go ahead with it, how can the house be best protected against groundwater and flooding, in case the levee fails? Although it has never happened in its 30 years of existence, you never know.

How is a ground floor and slab-on-grade (concrete slab) constructed in such conditions? Are there windows or doors that are more resistant to water than standard ones? We are planning to have the heating and electrical systems on the first floor. Which type of heating system is especially suitable for that? I would appreciate lots of tips and tricks 😀

I think that looks a bit extreme next to the village church... and I also doubt that the building authority would approve it. But you might want to keep it in mind just in case 🙂

How many floors are allowed?
Maybe plan only garage(s)/cellar substitute rooms on the ground floor and put the living space starting from the upper floor?

There is no prescribed development plan. The city told me to follow the neighbouring buildings. And they all have ground floor + upper floor, nothing more.

I would make sure to build the ground floor above the levee, so no water can get inside. :-)

Just kidding, had to say that.

A house located right behind a levee will probably cost more than a regular house that isn’t behind a levee and therefore isn’t exposed to flooding. On the other hand, the land for the house without the levee is likely more expensive. In the end, when you look at the total construction costs, both houses cost almost the same.

----> So???

I’m buying a more expensive plot of land and I’m not exposed to flooding, so I don’t have to worry about the levee breaking and all the potential consequences.

To clarify once more: I am not looking for a discussion about WHETHER we will buy the plot, but rather, IF we do buy it, what we should or must consider during the house construction process.

I would also appreciate reasonable answers. After all, we are taking the house building seriously....

This forum is here to support all construction projects, thriving on homeowner experiences, but it does not replace external, personal advice in difficult cases like yours!

Like many, you dream of building your own home and want to save significantly in a crucial area just because it’s trendy nowadays to expect everything for free 😕 What if one of the suggestions given here actually leads you into trouble? Who is liable when everyone comments under a nickname?

Take your questions to a certified building expert in your region and clarify the flood protection options with them. Since they will provide this advice in writing, you will also have recourse in the worst-case scenario! Of course, this consultation costs money; the expert’s profit and loss statement will not be filled with air and love.

Best regards, Bauexperte

...the expert’s income and expenses don’t get covered by just air and love @Bauexperte.. well, I often record such items in the accounting :p

Perios, I think the only sensible advice is what Bauexperte already mentioned: find a local specialist. They know the conditions, the surroundings, and can give you precise suggestions on what makes sense… and whether it’s really worth buying your dream plot. We’ve also looked at properties where a professional clearly advised against it... You won’t find a solution for this specific case on the internet.
