Hello,

the garden shed I ordered will be arriving soon. I have designated an area in the garden for it, where there are leftover building materials (curbstones, small concrete debris, and similar items). Gravel will be added on top of this and then compacted to create a stable base for the garden shed.

The garden shed comes with its own floor made of OSB3 panels and will be delivered with an underlying timber frame.

Now, I am thinking of placing the existing paving stones on the gravel, and then installing the timber frame on top of them. Or should something be placed between the paving stones and the timber frame?

Thanks for your feedback!

Hi, I did it the same way, and it works fine. If you feel that weeds might still come up from below, it’s worth spending a few dollars on weed barrier fabric, then put the stones on top, followed by the wood.

I have also placed terrace pads / building protection mats between the paving and the wood to insulate against rising moisture.

I did it the same way, so that air can also circulate a bit from below your OSB3 panels.

I have also placed building protection mats under the floor battens. This allows better ventilation in case of water exposure.

Thank you for the feedback.
Could someone please confirm the correct layering for me again?

That’s right, I also received the tip about the building protection mats.

Or if I understand correctly:

Gravel
(Weed control fabric if needed)
Pavers (or walkway slabs)
Building protection mats
Then the substructure
Garden shed

But that also means the pavers are simply laid on the fabric or the gravel. And the whole structure is supported by the weight itself or the contents of the garden shed?

Also, a follow-up question:

What is the best way to deal with the gap that will form between the back of the garden shed and the neighbor’s fence to prevent any weeds from growing there? The gap will probably be about 20–30cm (8–12 inches) wide.
I hope I expressed this clearly.
Essentially the brown strip at the back.

Construction site in the garden: gravel, rubble, and soil excavation, red wheelbarrow next to dark fence.
