We are currently planning the construction of a single-family house with a prefabricated house company using timber frame construction.

Now to my question regarding the structural engineering: We want the upper floor to extend over the ground floor in the terrace area. It is important to us that this is technically possible without columns (i.e., no columns in the terrace area). The planner has now said that this will not be possible without columns.

Now to my actual question: Is it possible that this would work better in terms of structural engineering with solid construction, i.e., with bricks, or is there no significant difference between timber frame construction and brick construction in this regard?

Maybe someone can help us here.

Best regards

, when it comes to

On the "left" side there is an overhang of about 3x12m, and at the front, towards the viewer, about 1.5x9m.

I think this will only work if you massively reinforce the floor of the upper floor accordingly. However, I am an amateur.

Didn't you say that your brother-in-law or someone like that has already built something similar? How was it solved there?

Hello!

Exactly, it is about this draft which is now with the technical department of the prefabricated house manufacturer for a more detailed review or technical inspection. What is certain, however, is that it doesn’t work without supports. With my brother-in-law, a column was made inside, that is, in the living room in the corner, which I also don’t like.

The reason I am asking: I am basically still flexible about how much the upper floor protrudes, for example instead of 3 m, then just 2.4 m. However, I would be interested to know if anyone knows whether, for example, more can be "gained" with solid construction than with timber frame, or if the same possibilities exist with both construction methods regarding the reinforcements you already mentioned in the ceiling/floor.

Technically, this is not a problem. Regardless of the construction method, steel beams can be used, for example. It all comes down to the effort, the costs, and above all, how bold and experienced the structural engineer is.

There are structural engineers who calculate well and cleverly save a lot of unnecessary reinforcement (in solid construction), while other structural engineers take the easy route and throw in a few tons of additional "fear bars."

Since you cannot choose your structural engineer, you will probably have to try to persuade the structural engineer of your construction supervisor well.

That sounds good. We haven't had a conversation with the company's structural engineer yet, only with the planner so far. Since they are now digitizing the current plan version and presenting it neatly in 3D, we will take a look at the column solution and then have a conversation with the structural engineer.

Thank you for the comments!
