Hello!
For a single-family house, is a structural calculation by a structural engineer required, or is a detailed design with the corresponding calculations sufficient? Some say a structural analysis is absolutely necessary, while others say it’s not needed for a single-family house.
Can you clarify this? Thanks!

For our prefab house with a prefabricated basement, two structural calculations were carried out. Structural analysis is necessary even just for the foundation, as the loads and load-bearing capacities need to be known.
We are also building in Bavaria, and I am still not sure which building class our single-family house falls under:
Building class 1:
Detached buildings up to 7 m (23 feet) in height with no more than two units totaling no more than 400 m² (4,300 sq ft), and agricultural or forestry buildings,
Building class 2:
Buildings up to 7 m (23 feet) in height with no more than two units totaling no more than 400 m² (4,300 sq ft),
Building class 3:
Other buildings up to 7 m (23 feet) in height,
Building class 4:
Buildings up to 13 m (43 feet) in height with units each not exceeding 400 m² (4,300 sq ft),
My initial guess would be class 4, since our house is definitely taller than 7 meters. What confuses me is that there are so many classes for buildings under 7 meters. Could it be that the classification is based not on the highest point but on the exterior wall height?

So, if you are building a two-story house and an occupied room is possible under the roof, the height is the top edge of your floor ceiling. If no occupied room is possible there, the height is the top edge of the floor on the upper floor.
