Static analysis required for single-family house

Definitely not.

Rhenish greetings

Probably a tent

For our prefab house with prefabricated cellar, two structural calculations were made. Without structural engineering, it doesn’t work, if only for the foundation; the loads and load-bearing capacities must be known.

We also build in Bavaria and I am still not sure which building class our single-family house belongs to:

Building class 1:
detached buildings with a height of up to 7 m and no more than two units with a total of no more than 400 m2 and
buildings used for agricultural or forestry purposes,

Building class 2:
buildings with a height of up to 7 m and no more than two units with a total of no more than 400 m2,

Building class 3:
other buildings with a height of up to 7 m,

Building class 4:
buildings with a height of up to 13 m and units of no more than 400 m2 each,

My spontaneous guess would be class 4, since our house is certainly over 7 meters in height. What puzzles me is that there are so many classes under 7 meters. Could it be that it is not the highest point that counts here, but rather the exterior wall?

Read further in the BayBo, it then says "Height within the meaning of sentence 1 is the measure from the top edge of the floor of the highest storey in which a habitable room is possible, above the average ground surface."

So if you build two stories and a habitable room is possible under the roof, the height is the upper edge of your ceiling, if no habitable room is possible, the upper edge of your floor in the upper floor.

We do not know what you want to build

In short, greetings
