Room and modular containers

Living containers

From housing modules to container tiny houses – use, law and fit-out.

Living containers range from a simple housing module for accommodating fitters to a well-designed tiny house with kitchen, bathroom and living area. Quality depends on insulation thickness, a construction with few thermal bridges, a ventilation concept and the building services. Anyone planning to live in one permanently needs a building permit and must meet the requirements of the German building energy act.

Typical uses

  • Tiny house as a permanent main residence on your own plot
  • Weekend and holiday home by the lake or on a campsite
  • Garden studio or home office with its own entrance away from the house
  • Accommodation for fitters and staff on assignments and major projects
  • Interim home during conversion, refurbishment or new build
  • Annexe or guest house for visitors and multi-generation living
  • Holiday letting as a glamping unit or tourist accommodation
  • Housing for apprentices, students and seasonal workers on company grounds

What to look out for

  1. Clarify permission before buying: permanent living almost always requires a permit.
  2. Plan with a high cube, otherwise headroom is missing after insulation.
  3. Take thermal bridges and ventilation seriously – they decide between mould and a healthy indoor climate.
  4. Get servicing costs quantified in advance; they often exceed the container price.
  5. For worker accommodation, compare hire modules with sanitary fittings rather than converting yourself.

Frequently asked questions

Can you live in a container permanently?

Yes, if the container is approved as a residential building and meets the requirements for fire safety, thermal insulation, daylight and servicing. Without approval permanent living is not permitted.

Is a living container warm enough in winter?

With adequate insulation, good heating and a strategy against thermal bridges, yes. A basic site container is not designed for it.
