How to correctly determine the depth of a garden cellar or dugout?

Building a garden cellar or dugout is a task that requires careful analysis and planning. One of the key elements that needs attention is the appropriate depth to which the structure should be dug. In this article, we will analyze the main factors influencing the optimal embedding of such a structure to ensure its durability, efficiency and effective thermal insulation.

Soil type:

The depth of a garden cellar or dugout depends largely on the type of ground on which it will be located. It is worth remembering that different types of soils require different approaches. Deeper burial may be necessary for soft, loose soils, while additional stabilisation measures may be necessary for sandy soils.

Climate and weather conditions:

Climatic conditions are crucial to determine the optimal depth of the cellar. In areas with harsh climates with long and cold winters, a greater depth is recommended to avoid freezing problems. Additionally, in areas with high rainfall, effective water drainage should be planned to avoid possible flooding.


The purpose of the garden cellar or dugout has a significant impact on the depth decision. If you plan to store food, consider a greater depth for better thermal insulation. On the other hand, if the cellar is to be used as a usable space, it is important to adjust the depth to the specific needs of the user.

Building Materials:

The choice of building materials also influences the depth decision. When using materials with low thermal conductivity, a shallower depth may be considered. However, when using heavier materials, it may be necessary to bury deeper.


The decision regarding the depth of a garden cellar or dugout should be the result of a well-thought-out analysis taking into account all of the above factors. Consulting with a professional, such as a geotechnician or architect, can be essential to ensure the durability and safety of your structure. Let’s remember that a well-planned and solidly built cellar can not only fulfill practical functions, but also be an aesthetic addition to the garden or plot.
