Looking for a 3x3 meter garden house with a high door

Is this moisture barrier as well as the Styrodur boards from Biohort or have you used materials from other manufacturers? The ventilation slots are included in the standard version, right?

Styrodur and the moisture barrier from the local hardware store or building materials dealer. The slots are included automatically.

Can you post a picture of how it looks with you?

Can you post a picture of how it looks on your side?

Unfortunately, I haven't taken any. If you go to the Biohort website. Under Products -> Garden Shed -> Highline Then scroll all the way down to FAQ. Everything is described there as well. Or search for foundation tips on Biohort. All variants are listed there. You can click on them and they are described with pictures too.

I would not look for gardenHOUSES, but rather for sheds or garage sheds or similar.
