Plastic shed base foundations?

Hello,

New here and after some advice, regarding a base for a plastic Keter shed i intend on buying but before that i need to get a base in place.
The shed in question: https://www.amazon.co.uk/dp/B00AFSU...lid=3J10Q8EJEJ6DJ&coliid=I1VNIY8PJUUVGZ&psc=1
A few pictures of the proposed base location follow to give an idea.

Ideally i want to build the base level up to the existing slab level which is circa 150mm above where the ground level is now.


Im looking for advice on how to go about bringing up the level, i was thinking about using the "council" slabs which are 50mm thick.This gives us 100mm to fill with either sharp sand or another material?
The plastic shed could then be fixed down into the slabs to stop it flying away.

It wont be heavily loaded its just for basic storage

Does this seem a reasonable way of going about it or am i better splashing out and doing a proper concrete base? Other ideas considered had looked at plastic shed bases but im not sure if i could just level the existing ground and place the plastic base down.

Are there any other aspects to consider such as drainage?

To be honest most sheds are fine sitting on a couple of fence posts with a foot square pad of concrete poured at either corner and a couple in the middle.

A concrete base is obviously the best long lasting solution but a fair cost if you were paying someone to do it.

Your slabs would do if you bedded them on a lean concrete mix if you already have them but if your were planning on buying them a few concrete fence posts or concrete lintels would be quicker to install and better.

You could gravel that area. Might not be a bad idea seeing there isn't much grass/dirt around to absorb moisture

Then lay some pavers down over the top and put the shed on that

If your really concerned about security/your shed blowing away then get some star pickets, drill holes in the corner of your base of your shed and then ram them into the ground

You can even attach the top of the star picket to your base if you want
