Hello everyone!

So far, I haven’t had much experience with building or renovating, so I’m a bit clueless.

I’m currently interested in a house that is a little over 30 years old and would like to do some of the work myself.

During the first visit, I noticed some unusual braces in the attic (about 50cm (20 inches) long, see photos) and I’m not sure what to make of them. They appear to be anchored in the floor and the exterior wall. There are four of them in the upper floor.

Has anyone seen something similar before?

Thanks in advance for your help!

I’m not familiar with this either. But it seems to me that these reinforcing bars are meant to hold the wall in place.

That definitely needs to be clarified first. Especially since the area wouldn’t be usable otherwise.

Thanks, I've been thinking along those lines as well.

Hello!

No guarantees:
I’ve never seen anything like this either, but it looks like it’s meant to transfer tensile forces from the roof. If you cut it, the roof will push the wall outward.

These forces can also be managed differently, for example by adding a stronger or additional purlin/steel beam or possibly steel brackets with sufficient tensile capacity, but for this you’ll need a new structural calculation and the corresponding building permit/planning permission, etc.

Best regards,

Oops,
this looks like a defect that occurred later on in the house, for example as described by @Dirk Grafe, and could only be fixed with such a device.

Personally, I would stay away from this. Maybe you could live with these metal parts – by arranging the furniture cleverly, they wouldn’t stand out – but the defect itself (even if corrected) would make me suspicious.
