Hello,

I would like to place a prefabricated garden shed (about 3x3m (10x10 ft)) for self-assembly on my "parking spot." The area is fully paved. Can I simply fix the shed to the paving with a few brackets and anchors, or do I need to remove the paving and pour a proper foundation?

Thank you very much

Of course, you need a foundation. Remove a few stones and dig a hole (for example, 30 x 30 cm (12 x 12 inches) and about 80 cm (31 inches) deep or similar). Fill it with concrete/cement or a similar material (for example, inside a 1 kg pipe) and after it dries, drill a hole through the paving stone and concrete. Insert the H-beam with a round peg at the bottom and secure it firmly by concreting it in place (or use a two-component adhesive, such as Hilti HIT). This method looks the cleanest in the end, as the beam protrudes directly through the paving stone.

Hi,

In my opinion, it depends somewhat on the material of the prefabricated garden shed and its location.

Location:
Is the site exposed to wind or not—that is, could wind or a gust of storm catch the shed, or is it in a sheltered area (e.g., a parking space between residential buildings)?

Material:
Is it made of lightweight components (such as metal garden sheds) or a solid wood structure (for example, a log cabin style shed)?

Type of paving:
Are the paving stones small standard size (approximately 10 x 5 cm (4 x 2 inches)) or larger, heavier stones (30 x 30 cm (12 x 12 inches) or 50 x 20 cm (20 x 8 inches))?

I would base my decision on whether to anchor the shed or not on these factors. For a sheltered area and a wooden shed, anchoring into larger paving stones should be sufficient in my opinion. For 10 x 5 cm (4 x 2 inches) stones, more anchors might be necessary. For sheds made of lightweight materials, I would generally recommend foundation work. For all other combinations (e.g., exposed location and a wooden shed), it depends on personal judgment and the type of paving stones.

We will secure our 2 x 2 m (6.5 x 6.5 ft) garden shed (constructed from solid 2.8 cm (1.1 inch) thick log boards) to 4 or 6 concrete slabs measuring 40 x 40 x 5 cm (16 x 16 x 2 inches) using anchors.

The forces that can act on a handrail like this are considerable. If the small structure is located in the neighbor’s conservatory, especially during winter, it is important to have proper insurance coverage.
