ᐅ Which type of foundation do you recommend for my garden shed? What would you suggest?

Hello

I want to build a garden shed in my yard.

As shown in the picture, I want to pave the covered area plus about 1m (3 feet) on the side.

Unfortunately, I don’t know what kind of foundation I need.
If I pour a concrete slab about 8x6m (26x20 feet) and lay the paving on a 3cm (1 inch) layer of gravel, won’t the water fail to drain properly?

Can an expert help me with how the foundation and paving layers should be constructed?

I would mentally divide it into three parts.
You can place the house itself on a concrete slab. According to traditional practice, you would first construct strip foundations and then place the concrete slab on top. You can find plenty of examples of this on YouTube and similar platforms. Alternatively, pure strip foundations are possible, or pad foundations. The foundation plan linked on the provider’s website shows (more schematically) the timber beams that form the substructure of the house. Based on that, you align the foundation (strip or pad foundations). When done properly, foundations should be frost-resistant. Don’t forget a solid connection between the house and the foundation (storm anchoring).

The paved outdoor area can simply be paved. The base consists of crushed stone (B2 0/32mm), then sand (0/5mm), stones on top, compacted, and sand again. There are plenty of guides available...

The supports for the surrounding canopy each require individual pad foundations, which can clearly be seen in the linked picture. Here you can embed H-anchors or other post bases in concrete, again at a frost-resistant depth.

That should run automatically, without manual intervention.

I wouldn’t recommend paving there. Compact the ground and use isolated strip footings or individual 40cm x 40cm (16in x 16in) paving stones, then place the wooden floor panel of the garden shed on top. This way, the ground can still breathe as air circulates underneath.

That might work for the garden shed, although I suspect the little building will end up leaning romantically after the third winter. But the person asking the question wants to add a lean-to roof, which requires supports. At a minimum, you need a driven post sleeve as a post anchor. The proper solution is a concrete-set H-anchor. After all, a storm could come at any time...

However, the original poster wants to install an extended roof, which requires supports. At a minimum, a driven-in sleeve as a post base is needed. The proper solution is a concrete-embedded H-anchor. After all, a storm could come at any time...

Oh, okay...

No, everything is still perfectly solid.
