Concrete block compressive strength

[forestboy]

Hello all,

I'm building an outhouse, 24ftx12ftx8ft tall, with a pitched roof made of 8x2rafters and 3/4 ply.

I'm using concrete blocks for the walls, but I note there are different strength ratings for the ones available.

What would be the minimum strength rating I should use?

The building is being done as permitted development and is exempt from building regs so there is no architect/structural engineer I can call on.

Some of the concrete blocks available have the word 'Scotland' tagged on to them - what does that mean?

Thanks.

Why is exempt from reg's?

Permitted development, forestry/agriculture.

The 'scotland' I think refers to building warrant needs in Scotland, but I dont know if that means a minimum Nm rating or similar.

Permitted development, forestry/agriculture.

You are confusing planning consent with building regulations me thinks.

No I'm not, PD forestry and agri builds are exempt from building regs.

Non PD forestry and agri builds are often not.

I assumed people would have known that, or not cared.

Any standard available blocks will be sufficient for a two and a bit metre high building.

Thanks, much appreciated.
