Have you ever thought about a practical storage cellar under the garden house in which you can store the crops from the area? The climatic conditions in a small cellar under the garden house would be optimal for this. Even if this project involves a bit of effort, adding a cellar to the garden house can definitely make sense.
How can you build a basement in a garden shed?
A garden house can have a basement before or after construction. When building a basement before construction, a pit is dug, gravel and sand is filled in, paving slabs are laid and sand-lime brick walls are built. A subsequent basement is more expensive and more difficult.
Is a building permit necessary?
A basement may make this necessary. Therefore, please ask the relevant municipality about the applicable regulations.
Basement before the construction of the garden house
This variant is the one that requires the least amount of effort because you can plan the basement before laying the foundation. Proceed as follows:
- Dig a sufficiently deep pit.
- A layer of gravel and sand is filled into this.
- Pavement slabs are then laid on top of these.
- You can build the side walls yourself from sand-lime brick. These have the advantage that they optimally regulate the indoor climate for storage.
- The cellar is sealed at the top by a stable, insulated wooden floor, into which a hatch is integrated.
Subsequent basement construction
If you later want to add a basement to an already existing house, this will be significantly more difficult and more expensive. In addition, the concrete floor slab is often not designed as a load-bearing ceiling, so that the static calculations required for the necessary building permit do not meet the requirements.
It is therefore usually cheaper and less complicated to set up a new garden house with a basement before construction.
Tip
A ground rent is a good alternative to the basement and is much easier to implement. All you have to do is dig a pit about forty centimeters deep into which a thin drainage layer of dry sand is filled. The edges are supported with formwork boards or bricks. Finally, the rent is covered with a wooden board. A small storage room, like our grandparents already appreciated, is finished.
