The habitable container is part of a modular construction system,
it is possible to use a single container for housing or to stack individual cells together to create modular buildings. The most well-known and basic examples of these assemblies can be seen on construction sites as temporary facilities for workers - the so-called building cells.
The construction of such a residential container is in most cases not necessary building permit, but it is sufficient to notify the building authority. For according to the Building Act, the notification to the Building Authority requires buildings for housing and recreation up to 150 m2 of built-up area, with one underground floor to a depth of 3 m and a maximum of two above-ground floors and an attic.
The skeleton of the residential container is usually formed by a welded steel frame with increased service life. The outer shell is insulated sandwich filling. The inner side is made of laminated chipboard or plasterboard, from the outside galvanized sheet with an easily washable paint. The roof is also usually made of trapezoidal sheet. The floor is again made of plywood or cetris board (concrete-chipboard) covered with PVC linoleum.
Containers can be fully equipped with sanitary equipment, heating and lighting. Due to the gradual development in the field of modular architecture, we can now also see a more luxurious variant of the material solution of the facade and interior cladding, eventually a gabled roof.
