Looking for pics of external nesting boxes

[ONSTAD1]

I need to attach a nesting box 26x13x13 to the outside of my small coop. I'm going to try the deep litter method so the bottom of the box needs to be 6" above the floor of the coop. Does anyone have pics of construction phase of box. ie how you attached it to the sheathing or frame?
thanks,

mo

this is the coop (unfinished)
the boxes are going to go where the egg door is (just open on left side of coop)

I cut a hole in my coop and built the box seperate with cleats around edge and screw it to outside of coop
