South facing 35 feet deep, 40 feet wide. I am thinking of redesigning. Would a court yard style work? I was thinking of persuading neighbours to agree to allowing me to do rendered white Walls, paint the fence White if the bastards won't let me and have low level retaining Walls for planting. Would plain paving slabs look ok? I was going to put in ever green foliage, with White climbers and White perennial planting, and some veg in-between.
