Afternoon all,

I am about to deck the bottom of my garden. The are is surrounded by the boundary fence on 3 sides.

What is the standard practice with regards to how close the decking frame is to the fence?

Can it be right against the fence posts?
Should I leave a small 2-4 inch gap between the posts and frame for maintenance?
Etc etc

Logic would dictate a gap big enough to allow for the fence post/foundation to be removed/replaced if/when necessary. Or if you're not bothered about that then probably an inch or something.

I was going to leave a 4 inch gap so i could get a kango down to break the concrete around the fence posts should i ever need to replace them, however ive just replaced the entire fence so they wont need doing for a good few years now.

At the back where the decking will be at its highest, ive sat the fence on 150mm timber, and as the decking slops the fence panels are sat on 100mm and 75mm timber, so the decking wont actually go up the fence, it will be more or less at the height of the timber.
