The wood frame you can see in the picture is just a temporary construction so I can board up the back of the house while we're waiting for the doors.
Here's a wider shot:
Does that make sense. to be honest not to sure how the doors work,according too the picture your putting them on a runner fixed to the brickwork which is flush with ground level,then going to put a aco drain in front of them is that right lol, look father i reckon nosealll might be a better judge, i never come across nothing like it,no wonder the builder scratching his head, cant the sliding doors go on at least one course of bricks? got a photo of doors ?
