ᐅ Looking for information about my Massa house

Hi,
I own a Massa house built in 1981. So far, so good...
Due to a construction project, I now need the structural engineering documents for the roof.
However, I bought the house second-hand and unfortunately don’t have any detailed plans, especially no structural drawings.
On the copy of the floor plan that I at least have, the house type is unfortunately not identifiable...
The project number starts with 752...

Does anyone have any idea how I can proceed?

Thanks,
Jan

Inquiries about Massa Haus, which is now called dfh and includes Okal Haus, Allstav, and Massa Haus. Homeowners of prefabricated houses rarely received the detailed construction plans, usually only the nicely colored floor plans.

The manufacturer still exists and should be able to (re)identify their models. There will of course be a building file at the building authority, because regardless of whether the project is "finished" or not, there must have been a building permit/planning permission with structural safety certification.

Hello again,
I have already inquired with the prefabricated house company...
The reply was: project files are deleted after 10 years, so no information is available...

Not very helpful...

But I will follow up on the idea with the building authority / planning office – thanks for the suggestion.

See you,
Jan
