Here's a poser - possibly for the decking experts: Outside, non critical application.
How deep joists do you reckon would be good for a 2ft unsupported overhang (is that a cantilever??) at one end of a total span of 8ft?
6x2" maybe?Lets say the max likely load is 100-130kg per joist (adult person or few bags of cement) centred about a foot into the overhang and we're using C16 pressure treated decking joists.
And if it's OK lets stick to the exact question - no "do it properly and lay more concrete" please - I'm happy to "take liberties" here (John and Adam faint)...
I don't think the "sagulator" does unsupported overhangs - though I admit I could maybe have missed it.
Cheers

Background as someone will want to know WTF is going on :->
Old shed is leaking and not economic to repair. However I am at the phase in the house where dry storage would be damn useful and I need to get on with stuff without another big dependency. This needs to be a splat - clear - erect job.
Turns out, like so many things here, the old shed was bodged (quelle surprise!)
It's an 8x10ft on a 6x12ft well made concrete base. There is an illusion of some extra concrete at one corner but it does not appear to go very far along. Current shed sits on 2x4 bearers which seem to take the overhang to a point.
I actually do want an 8x10 or even an 8x12 shed.
I need to continue to sit it on bearers as is the current one to gain some height or the doors will foul the slopes in the ground.
I do not want to tit around with more concrete. I do however have a load of paving slabs and some sand - but not enough to make a "really good" base extension.
