We had a 24ft x 12ft block shed built using single skin construction. We used a DPC and the builders were professionals, so all the blockwork was up to scratch. However, during heavy and prolonged rain the blocks would let water penetrate through and they would be wet to the touch, although not actually getting to the stage of dripping. Our builders ended up rendering the outside (only cost a couple of hundred quid for our huge structure, so shouldn't cost a lot for yours). This stops the water penetrated through and creates a lovely dry environment. I suppose its how dry you need it. If it is literally going to be a shed, for lawnmower etc, then you could probably just get away with painting it, but if you're going to be spending any amount of time in there, I would spend that little bit more and get it fully waterproofed.
On the roof we used tiles with a breathable membrane underneath.
