Side extension - Is a set back required?

DQuest

I'm currently looking into having a single story side extension built.
I believe it will fall under permitted development, as I wish to extend by less than half the width of the original house, it's below the height limit, etc.
However, I have seen mentioned in various places that a "set back" may be required; where instead of the extension sitting flush with the front of the house, it is instead set back by 20 cm or so. I can't find any mention of this set back within the permitted development guidelines, however.

If my extension falls within the permitted development guidelines, does the council essentially have no say in the matter regarding details such as the set back distance?

Thanks for any help.

Providing the proposals comply with the PD guidelines, then the LPA cannot apply or enforce Local Plan policies.

For formal non-PD applications, these set backs and set downs are common among LPA’s but they do vary as to how much of a set back and set down they consider to be adequate. Also, they really only apply these design details for two storey extensions, not single storey. When people are proposing two storey extensions, they can set back both the ground and first floor front walls or keep the ground floor flush and set back the first floor wall. As well as set backs from the front, they can also request them to the side boundaries but again... only really where two storey extensions are concerned.

Brilliant, that's what I had hoped was the case. 
Thanks very much.

It can help if it's brickwork to have a small set back. It means you don't have to follow the existing gauge and tooth in. This can be tricky, especially when working with different sized bricks.

And can also help with the roof detail as it’s a lot easier and neater for a verge to finish up against a flat wall face as opposed to seeing an overhang.

Sounds like it's still something to consider then, definitely a question for the builder when it comes to it.

Thanks all for the advice
