Is a bungalow possible on a slope of around 20%?

We are looking for a rather larger plot of land for the construction of a bungalow. We have now found one - however, the plot has a slope of about 20%. The plan is to build without a basement. The access road is practically the highest point. Is it possible to build a bungalow despite the terrain slope? Thanks for your inputs and comments.

Yes, it is possible, but it costs a lot of money. We are similar. We had the entire property filled up and now have a slope of 1-1.5m around the house. It's not quite a 20% gradient, but the principle is the same.

At 20%, one will probably work with stilts, right?

Ok, then I'll ask specifically what "eine Stange" means. The property itself would actually be ideal in terms of size and location and is also reasonably priced. For us, it could also be slightly less than 20%. The "lower" limit will also require a slope of the same magnitude on our side.

I would build a bungalow, but with a basement, which serves as a substitute for an attic. So I would move a nice office or the children's rooms or bedrooms there with access to the outside. However, everything depends on personal space requirements as well as the slope orientation.

Best regards in brief

That will probably not be possible without a basement inserted into the slope. Depending on the plot layout, embankments would also be too space-consuming, including the sloping and triggering setback areas, which must also be located on the property. From a design perspective, such a massive embankment is also rather questionable. A clean and architecturally-structural solution that fits the house is more advantageous, probably also financially.

Regarding the costs, something can only be said after a preliminary draft and knowing all the framework conditions. Basically, the starting situation is of course somewhat extreme, but also interesting. When calculating the total costs for the construction project, the costs for a bungalow in a topographically absolutely simple location, which causes no additional costs, would have to be offset against the increased foundation effort on your dream plot. Possibly a more expensive but simpler plot might be cheaper in the overall balance.
