I'm lucky enough that the house will be nearby so I don't need a shed - although grand ideas of expansion plans might see one later on.
I think I might have to go a bit deeper for the footing as the soil seems very soft (I've been told you can grow just about anything there). I suppose I'll have to start digging and see what's underneath.
I'm going to have to consider the footing/pier carefully, as I expect the platform to be higher than yours...
