In a storage unit, the material is stacked up to the available height whenever possible. The size of the storage units is therefore indicated with the corresponding volume in cubic meters/m³. (One cubic metre corresponds to the volume of a cube with an edge length of 1 metre.)

We have storage units in various sizes from 8 - 38 m³ and a height of 2.50 - 2.75 m depending on the storage location. We would like to give you a few examples so that you can imagine the volume:

8m³ correspond to...

  • an area of approx. 2.90 - 3.20 m²
  • about the furnishing of one room

20 m³ correspond to...

  • an area of approx. ca. 7.30 - 8.00 m²
  • about the furnishing of 1.5 to 2 rooms

30 m³ correspond to...

  • an area of approx. 10.90 - 12 m²
  • about the furnishing of 2.5 to 3 rooms

38 m³ correspond to..

  • an area of approx. 13.80 - 15.20 m²
  • about the furnishing of 3.5 to 4 rooms

Store correctly and space-saving

It is of course advisable to store any material in a space-saving manner. Pack small materials in stackable, sealable cartons and not in laundry baskets, carrier bags, paper bags or similar. Large furniture should be dismantled and the individual parts (e.g. a wardrobe or a double bed) should be placed upright in the storage box. In general, many pieces of furniture can be stored on edge, such as tables and sofas.

As with Tetris, the motto here is: think first, then stack!
Think about how to optimally store your storage box and even draw a plan if necessary.

Please note the following:

  • Easy access: Build a corridor between your stored objects and ensure freedom of movement.
  • Leave some space between stored objects and walls for air circulation.
  • Ask yourself: 1) What do I often need? 2) What do I need from time to time? 3) What do I not actually need? The third one you store at the back and at the bottom. The second one a little further forward and the first one within easy reach.
  • Important here: heavy and large things generally belong on the floor, small and light things upwards.

Why rent a storage unit at all?
About two-thirds of our self-storage customers are private individuals and one-third business people. In principle, we address all those who do not require existing storage space. Classic storage customers do not exist in either the private or the commercial sector, as the reasons for storage are very different.

  • Lack of space in apartment, cellar or attic
  • New home is not yet ready
  • Moving to retirement home
  • Apartment consolidation
  • Separation
  • Inheritance
  • Extended stay abroad

Reasons for commercial use

  • Lack of space in office, warehouse or archive
  • Seasonal storage (e.g. restaurant garden furniture)
  • External archive (e.g. storage of medical or legal records)
  • External storage (e.g. for online shops)
  • Storage area for freelancers
  • Temporary storage for semi-finished goods
  • Spare parts storage
