Breezeblock Shed - What Neuton strength?

[thundyuk]

Hi there,

I'm building a replacement shed to get rid of my ageing metal eyesore at the end of my garden.

It's going to be 4x3x2.5 (Length,Width,Height) with a flat roof. I'm fine with the building work but I've only used brick & cladding with supporting framework before.

What strength / type of breezeblock do I need to use?

Thanks
