Window set back distance

[mjc55]

Trying to decide how far to set the windows back in on our Pod build.

 

Vertical timber cladding and I was contemplating about 80mm or so from external cladding.  Not sure if there is a standard for this hence wondering what others did!

Is it insulated? If so it should straddle the insulation where we that is, other than a set distance.

 

If not insulated then any distance to suit how things look
