Building a small breeze block shed

[mountdale]

hi,
I plan to build a small shed in my garden just to store things like lawnmowers, shears and fishing gear in.
I plan to build it using just the 4 inch lightweight breeze blocks as i have before, along with a flat sloping roof.

My question is how deep would i need to make the concrete base/footings for this, to fill with concrete?

Someone had suggested 3 foot but looking at this it seemed a bit excessive for what i am trying to build here for storage?
Many Thanks

You need to put in foundations these could be 600mm deep plus dependent on ground conditions and trees etc. You might get away with less but why risk it?

You could do a 'raft' or you could just do a slab and a build a timber shed.

hi thanks for this and appreciat what you say! It just seemed excessive!
We want to go down the block route as opposed to timber though!
Can i just ask what you mean by a 'raft'?

A raft foundation has a reinforced edge beam cast with the floor slab.
But really just dig down and do your strip/trench foundations it wont take that long to do and then you'll know it's not going to go anywhere.
Depending on your area you might not have to go down too far.

ok many thanks tomfe
should i do the foundations first and then dig the area for the floor/base?
How thick should this be?
Thanks
