No. You should not assemble your shed or summerhouse directly onto grass or bare soil. Grass and soft soil are not firm or stable enough to support a garden building long‑term. Placing a building directly on grass or soil can lead to:
Movement, subsidence or uneven settling as the ground compresses under weight.
Damp and rot issues, because moisture held in soil and grass can transfer to the underside of the building.
Doors and windows going out of alignment, making them difficult to open or close.
Invalidation of your product guarantee, since Tiger Sheds requires a firm, level base for installation.
Instead, your building must be installed onto a firm, flat, and level base made from a durable material such as concrete, paving slabs, timber bearers or an engineered base system before assembly begins.
EcoBase: A Suitable Alternative to Traditional Bases
If you want a base solution that avoids full concrete slabs or paving, the EcoBase Fastfit system is a practical and user‑friendly option. It is designed to:
Provide a firm, strong and well‑drained base using interlocking recycled plastic grids that sit on top of prepared ground.
Include a permeable membrane to suppress weed growth under the base.
Be quick and easy to install with no specialist tools needed.
Remain durable and long‑lasting, as the grids are rot‑proof, chemically inert and reusable.
EcoBase grids can be laid over levelled grass or soil once you’ve prepared the area (e.g. mowing the grass short, removing stones and ensuring the surface is reasonably even). The system can be filled with gravel or left with the grids in place to create a stable base for sheds, summerhouses and other timber buildings.
However, even with EcoBase it’s important to level and firm the ground first. In soft, uneven or high‑moisture areas you may still need to remove turf, add a layer of compacted sand or gravel, and check that the base area is flat before installing EcoBase grids.
In summary:
Do not build directly on grass or soil.
Always use an engineered base such as concrete, paving or EcoBase to ensure a stable, level and durable foundation.
