I would think that a single story rear extension is much more likely to get approval than a doublestory side one especially if there is a precident on the street. Planning decisions are often very precident driven.
Town or Parish council comments are also often very important and it always goes down well to talk to your neighbours about your plans before they find out by a notice posted at the foot of the house.
Of course listed buildings and conservation areas complicate things but I'm guessing these don't apply to you
The 45 degree rule is commonly applied see here:

This council only applies it to double story extensions
but here:

Wrexham seem to apply it to single story extensions too.
If your council applies to to single story extensions then a 5 meter extension is very likely to fall foul of it.
I'd suggest you give them a call and ask what rules they apply. They're likely to be surprised and pleased to have somebody talk to them before putting in for permission and you're likely to save a lot of time and money if you clear any obvious hurdles with them first
