Concrete Base Question

[morg]

Hi, sorry for the new topic, bit of a dilemma now. Just one question please.

The picture below should say it all.

Basically the shed I wanted to build is quite tight within the wall space (including overlap)... So if I do go ahead with it, the base will be uptight against the wall with NO gap (just 2 sides). Will this be a major problem for water? Or should there be a gap for the water to drain?

Perhaps I could create a small gully for the water to drain?

Please suggest the right method, I really appreciate any help, thank you

just lay teh slab with a slight fall away from the house, it will drain under the shed and away from the wall then

good idea mate, thanks.

its not a house wall though, just a 6ft wall (i think the previous tenants were building a garage, but only did half of it). That's why the shed will fit nicely in there, however im contemplating taking it down now, because i just realised, I will need access to paint the shed... i think it would be best to take it down.

yeah, I'll take it down sorry

Why don't you use the wall as one side of the shed, build another wall opposite, and use that to hold up the roof. That's half the shed already built.
