will the rain run off onto that bit with the wall?
Thanks for reminding me about that.
Yes, the rain drops off the roof onto the top of the wall.
At the moment the wall has no topper on it but the plan is to find some kind of gutter tile that doesn’t look too ugly and can be trodden on.
It doesn’t really show but the wall slopes very slightly down from the corner nearest the camera to the far end. The hope/plan is that the water will fall from the drip plank on by the roof down into this ‘gutter’ and run away off the end of the wall.
I am really glad you reminded me of this as I couldn’t remember why I hadn’t ordered enough of the coping stones used on the patio side.
See, it is worth sharing the progress.
