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.

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.

 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.
