Am I the only one here who doesn't understand why the cantilevered porch roof wouldn't work? We did it exactly like that at our place, except our porch roof is free-standing and not supported on one side.

I understood it this way because there is no concrete ceiling on the interior side. So how else would you attach the canopy?

We also do not have a ceiling at this point, but a continuous ring beam was basically poured, which apparently supports the porch roof. This, combined with the recess for the front door, was apparently sufficient.

How was that thermally separated? Or do you now have a metal plate at the ring beam including a significant thermal bridge?

No, an Isokorb was installed there.

I think that’s how we will do it. That’s a good idea.

The ceiling is finally scheduled to be installed on Thursday. Steel beams for the garage have already been delivered and still need to be positioned.

Maybe I missed it earlier in the forum thread, so here’s my question:

Did you complete the house planning entirely by yourself, or was an architect, structural engineer, or building engineer involved? Did you hire a company for this or do you know someone?

For example, who decided that the garage roof would have steel beams?

Specific question: The garage shares a wall with the house (picture 104225). I’ve never seen that before. Are there no regulations requiring the garage to have its own separate wall?

Best regards,
Iwan
