Proof of stability for garden shed - Who knows about this?

Hello,

I ordered a garden house (blockhouse 40mm, 6m x 2.5m area) from a provider online. Unfortunately, such things require approval in Saxony, which has already been done. Unfortunately, I still have to submit the structural stability certificate.

Does anyone have a good tip (extensive web archive with many static calculations of existing models, own experience, (supra-)regional specialized provider for such calculations, private mediation via PM, ...), on how I can avoid commissioning this from the manufacturer (who wants to charge a lot again)? Technical data is available.

Thanks and regards,
Steph

No one has an idea?

Calculate it yourself (or have it calculated) or simply ask the manufacturer. That will probably be the only truth.

Alternatively, find someone else who wants the house and then share the costs. Or split into thirds and quarters. Depending on your sales success.
