Planning a wall correctly - that's how it works

For freestanding walls, a lot of planning is necessary in advance, so that the construction of the wall will succeed in the end. In the interior, walls must be planned accordingly, so you will experience no unpleasant surprises later. What should be done in both cases, read here.

Freestanding wall in the garden

For a freestanding garden wall, you must pay attention to the following when planning:

  • the soil condition
  • the necessary foundation
  • Height, length and position of the wall
  • in case of slope support, also on the necessary technical regulations that apply for this

soil quality

If you excavate the ground, you may need to resort to machinery to dig the foundation trench. This is especially true when the ground is interspersed with stones, or is particularly heavy.
Also check in advance if the ground could settle. If this is the case, you will need to adjust the foundation accordingly. Also plan the amount of ballast and the amount of concrete required for the foundation.
Also check the height of the groundwater level. If the depth of water is too deep, you must either plan for drainage or, if necessary, use pumps.


The foundation must always be in the frost-free area. As a rule, you start from a depth of about 80 centimeters at the foundation.
For a freestanding garden wall, you can usually adjust the foundation width to the wall width.

Height, length and position of the wall construction

Where you can build your wall and what distances you have to comply with buildings and property boundaries, contact your local building authority.
There you will also learn what conditions apply to the permissible length and height of the wall on your property.

Hang support

For the interception of a slope a normal natural stone wall is usually not allowed. Here special rules must be observed during construction.
Slopes that are more than 1 meter high can no longer be intercepted by ordinary walls. Here you must either use gabions, or build a so-called heavyweight wall. For this you usually need professional help.
Up to a height of 1 meter you can still support with a drywall. But also plan here a necessary drainage.

Planning of interior walls

When planning walls in the house, you have to consider a variety of requirements.
As a rule, you always need an architect to design a load-bearing wall, as this is about the statics of the building. Load-bearing walls should not be built by themselves and should never be altered or removed.
On the other hand, you can move partition walls yourself if necessary. Pay attention to:

  • Material (drywall, lightweight concrete blocks, limestone)
  • wall width
  • Requirements for sound insulation and possibly also for thermal insulation
  • wall connection

The simplest are plasterboard wall systems. For all other wall types, it is best to consult an architect beforehand.
