For all of our storage buildings, storage tents and container shelters we have structural calculations available (in German or English). These are available on request and free of charge.
These structural calculations always meet the ′Eurocode′ standard ensuring wide European and International acceptance. To maintain the legal status, we only provide the original untranslated documents in the German or English language. Should this cause you any difficulties, you can use these documents as a basis to ask a local engineer to draw up a translation or structural calculation in your own language which meets your local requirements

That depends on the product and the local regulations. A permit is usually not necessary for temporary placement. For (semi) permanent placements, it’s best to contact your municipality.

Placing multiple Workbox covers behind each other allows you to create a shelter in multiples of 20 feet.

In the product specifications you will find the maximum wind and snow load as described in the official structural calculations. We recommend that you only place the product in wind and snow zones that do not exceed these standards. If you nevertheless choose to install the storage building or tent in a region with higher maximum wind and snow loads, please bear in mind that this is at your own risk.

The supplied container clamps require an container edge of 50-80mm in height. Our clamps cannot be fastened without this edge and the shelter will then have to be attached to the unit alternatively for example using screws or by welding.
If you would like a front and/or back wall, the unit also must be between 259 and 290 cm high and be equipped with standard ISO container corners at the top and bottom.
