Bases for sheds – It’s all about the base


Bases for Steel Sheds are vital. Wooden Sheds just need blocks as a foundation (you can see how many blocks you need here)., but for Steel Sheds, a solid , level base is literally the foundation. We make every effort to make sure you’re aware of the importance of this when you buy a steel shed from us. You’ll have to click to agree to this term when you buy any steel shed from us:

“A solid, level base (covering the full surface area) must be in place before our team can assemble the shed. It cannot be laid on grass alone. If the area is not prepared before our team arrive, the assembly may not be possible and an additional charge may apply for refitting”

It’s pretty straightforward, right? Have a solid, level base in place and you’ll have no issue. However, we’re here to set out exactly what is good and what is bad.

Correct Bases

  1. The Solid Slab

A solid, level concrete base with grass around it. The base is raised and it's perfect to put a shed on.

Here we have a perfect example of a concrete base. it’s solid, level and there’s a bit of room at the back too. If bases for sheds could have lips, you’d kiss this one. 10/10


2. The Neat Concrete Base

A Solid level base made of slabbed concrete against a garden wall. There is a bush nearby but which is not encroaching on the base

Here’s another spiffing job. This is neat, level and solid. It’s larger than the size of shed going onto it. It’s a perfect job.


3. Concrete Alternatives
a. Rubber Slabs

If you don’t want to go down the concrete route, other materials that are acceptable are these hardcore, thick rubber slabs. They can be laid on the grass and are thick enough to take a shed’s weight also. You’ll get them in most building suppliers.

b. Decking

You can also use Decking for a base for your shed. While this isn’t something we’d recommend straight off the bat, it’s a suitable alternative, if it’s a solid decking structure. You do have to remember that Decking will rot over time and your shed may sink into it if the decking is not correctly supported. For these reasons we only suggest Decking if you the customer are happy that your Decking is solid.

c. The Iron Base

We offer an Iron base for our 4 smallest Classic Steel Sheds (i.e. the 6ft x5ft, the 6ft x 8ft, the 8ft x 6ft and the 7.5ft x 7.5ft). You can see it here.

A Base for a steel shed. it's a large, black steel frame with a silver lip on one side to accommodate the shed's door. It looks like an old window, one large square divided into 4 smaller segments. One side is twice as thick as the other three.


Other suitable alternatives include hardcore stone and patio slabs!



Incorrect Bases

Alright. Here’s the fun stuff. These are 100% unusable

1. The Hollow Core Base

An unacceptable base for a steel shed. It's concrete blocks around the edge and an internal mix of stone and gravel. An unacceptable base for a steel shed. It's concrete blocks around the edge and an internal mix of stone and gravel.

There’s absolutely no internal structure here. There’s less internal fortitude here than there is in a Jelly Baby. As you can see, when the shed’s internal frame was placed on this base, it just folded in. It’s utterly useless.


2. The Off-Kilter Base

an uneven concrete base. There is a visable 1 inch gap and 1 inch heigh disparity between the two bases an uneven concrete base as seen from above. There is a visable 1 inch gap and 1 inch heigh disparity between the two bases

Yikes. This is solid, but it’s as sure as hell not level. It’s visibly crooked as well as there being at least an inch gap between the two sets of slabs. You’d see straighter lines at an architects Christmas party. Putting a shed on top of this will lead to it leading – this can cause doors to swing open or misalign.

Please don’t do this.


3. The Bonfire Base

A base made entirely of Wooden Pallets in a back garden

Ah. Ah dear. This one hurts to look at. It’s just pallets. It’s just manky old pallets that have been arranged to look like a solid level base. This is not solid at all. One misstep and you’re going through your shed floor. Jesus wept.


4. The Individual Slabs / Artistic Base


You might be surprised to learn that here at Sheds Direct Ireland, we’re big fans of modern art. It’s enjoyable to look at in galleries. However, it’s not great to be influenced by it when you’re laying your base. The shed would not be level sitting on this monstrosity. It would be potentially rocked or moved by high, wintery winds. Similarly, because it’s not solid the entire way through, the weight would be dispersed poorly and you could end up breaking a wooden floor by simply walking on it.

Leave the abstraction to modern artists. Get yourself a solid, level base.


5. The …Honestly, I don’t know at this stage

A solid level base made of iron that has just fallen into a hole

In some respects, this is nice – in the sense that it’s nice to know that after years of putting up sheds there’s still bases for sheds out there that have the capacity to charm and confuse you in equal measure. You can see in this picture, we have an iron base which is normally placed on grass or soil. The ground is usually just levelled out and the iron base is placed onto that. In this case, it’s just plonked into an old, empty pond at an angle.


Closing Words

It’s all about the base. And your base MUST be:

  • Solid
  • Level
  • Larger than the base of the Shed
  • That’s literally all there is
