FAQ - Frequently Asked Questions

General Questions

What dimensions are possible?
Container sizes from 2.5 x 2.5 m to approximately 15 x 10 m are possible. Smaller/larger dimensions may also be possible under certain circumstances.

Are the containers stackable?
No, not at the moment. This means multi-story container constructions are currently not possible.

Can multiple containers be connected to form a complex?
Yes, multiple modules are prepared and connected on-site to form a complex (sealing and cassette cladding).

Is a building permit required?
Since each federal state and municipality has its own regulations, we recommend that our customers inquire with the relevant building authority beforehand.

Can a container be used as a garage?
Yes, but only with reinforced flooring and a suitably prepared base that must be fully supported.

Can the container be received without cladding?
This is possible but must be clarified individually.

Can tiles be installed in the container?
No. Due to the structural design, the floor slightly flexes, causing the grout to crack.

Are concealed installations possible?
Yes, but only by the client's construction side (e.g., using OSB or plasterboard).

Can Risto provide sketches and proposals?
After receiving an order, we are happy to provide sketches and proposals.
