Permitted Development. How close can 2 structure sub 30m2 be

[roca1976]

I am looking at a car port, ideally it would be 3m x 12.5m however that would take me outside of the 30m2 rule.

If I was to build two 3m x 6m car ports end to end how much of a gap would I need to leave to avoid any dispute- can't find any guidance online and unlikely either planning or building control would happily provide information on a (legal) dodge.

The plot is substantial so won't affect the 50% rule and the port will be 2.49m high, 1.5m off the neighbours boundary (garage with no windows) and open on 3 sides.

cheers.

The 30m2 is nothing to do with planning

the 30m2 bit is B Regs

it just says detached,
can you slip a fag packet between them?

no flashings or joining??

Apologies yes, building regs.
My plan was to build it close but not quite touching!
