Garden house on paving - fastening

Hello,

I would like to place a prefabricated garden shed (approx. 3x3m) for self-assembly on my "parking space." The area is fully paved. Do I just screw the house onto the pavement with a few brackets and dowels – or do I have to remove the pavement and pour a proper foundation?

Thank you very much

Of course you need a foundation. Remove a few stones, create a hole (e.g. 30x30 cm and then 80 cm deep or something similar), fill it up with concrete/cement or something similar (e.g. into a [kg-Rohr]), and after it dries, drill a hole through the paving stone + concrete and insert the H-beam with a round pin at the bottom and also secure it with concrete (or fix it with a two-component stuff, e.g. [hilti hit]). In the end, this looks the cleanest because the beam sticks out directly through the paving stone.

Hi,

in my opinion, it depends a bit on what this prefabricated garden house is made of and where it is located.

where it is located:
Is the location exposed to wind or not - i.e. can the wind / a gust of storm catch the little house or is it a sheltered area (e.g. parking lot between residential buildings)?

what it is made of:
Are they light components (e.g. these metal garden houses) or a house made of solid wood (e.g. a log cabin)?

what the pavement consists of:
are these the 10 x 5 "standard Otto paving stones" or larger (heavier) stones (30 x 30 or 50 x 20)

I would base my decision on that, to what extent I need to anchor it or not.
In a sheltered area and wooden house, in my opinion, anchoring in larger paving stones should be sufficient. For 10 x 5 stones, possibly set more anchors.
For a house made of light material, rather recommend foundations.
For all other combinations (e.g. exposed and wooden house) depending on personal feeling or paving stones.

We will secure our 2 x 2 m garden house (solid made of 2.8 cm log boards) on 4 or 6 plates 40 x 40 x 5 cm using dowels.

The forces that can act on such a retaining wall can be considerable. If the little house is in the neighbor's conservatory, one should be well insured.
