I have built several garages for my self, I built a single skin block garage the walls got wet through to the inside when it rained, even the rendered one with water proofing in the render.
So the second one was cavity walled and is the bees knees.
Third is a prefab concrete, now I think the water ingress problems I have always noticed with them could be solved. First they are built onto a concrete base which goes out under the walls so the rain water runs down the walls and in underneath them, I would look to solve this problem by, once the garage is built, placing a plastic sheet DPC suitable over the base inside the garage and up the side 50mm plus, I would then concrete screed the floor with a 50mm thick layer. I would also clad the outside of the garage (to give the water proofing benefits of a cavity wall) my first thought is to do this with fence panels which may be the cheapest easiest way. Also these garages can be picked up second hand so could be a cheap option.
I m sure others will have their observations on this I will look forward to them.
