Foundation and flooring for a garden house without a floor

The necessary basis for a small tool shed

A solid, level base plate is recommended here. This consists of a gravel and a sand layer, on which concrete slabs are laid. This goes very quickly, is not a problem even for laypeople and is usually cheaper than a concrete foundation.

Larger arbors require a stable substructure

For more stability, larger garden houses should always be built on a frost-proof concrete foundation. There are different types:

  • Slab foundation
  • Point foundation
  • Ring foundation
  • Strip foundation.

The effort is higher, but thorough preparation pays off. The house is stable for many years and no moisture can penetrate from the underground.

The floor

The flooring is based on the future use of the house:

  • In a tool shed, which is often entered with wet and dirty shoes, it must first and foremost be robust.
  • If heavy equipment is stored in the garden shed (7.70 € on Amazon *), the load capacity is also important.
  • If the arbor serves as a second living room, in which you can also read or celebrate in a relaxed manner, an optically attractive floor covering ensures a cozy room atmosphere. So that you don't get cold feet, you should additionally insulate the floor.

Which materials are suitable?


In a garden house made of wood, laying a flooring made of wood is obvious. In this case, a good foundation is important so that no moisture from the substrate, which could lead to mold, can penetrate into the floor. A matching design on the walls and floor is visually very appealing.


PVC is easy to lay, easy to care for and inexpensive. This floor covering is ideal for versatile use of the arbor. PVC requires a stable substructure, for example made of OSB panels. On the other hand, it is not suitable as a sole covering, since the air-impermeable plastic promotes the formation of mold.


Easy-care and robust tiles are available in a variety of variants. They create a cozy and visually very appealing overall impression. In the frost-proof version, they are even suitable for the uncovered terrace area. However, tiles require a solid, professionally manufactured substrate.


If you are planning a wooden floor, you can safely use old paving slabs for the foundation. Since these are covered and no longer visible, the costs for new panels can be saved.
