Hello
This is a garden shed (about 3 x 6 m (10 x 20 ft)) that requires a foundation. The shed is located practically in a field, making it difficult to use large amounts of concrete. The base is planned to be made from structural timber measuring 12 x 12 cm (frame 3 x 0.6 m (10 x 2 ft)).
Now the question is whether a "proper" foundation (80 cm (32 inches) deep) is necessary here, or if "concrete footings" alone would be sufficient. If a deep foundation is required, I can only imagine a pier foundation (digging holes with an earth auger and pouring concrete).
Thank you!

According to the bending moment b×h^3, you can also use a 6×12cm (2.4×4.7 inch) board set vertically. It can withstand the same load but might require joist hangers or something similar. However, 12cm (4.7 inch) structural timber is already quite expensive at the moment...
