This is a contemporary take on trelliswork in a much smaller garden than yours. They've chosen a pale grey paving and grey granite setts to go with the rendered walls which are also painted a pale creamy colour. As you already have lovely walls, our scheme will be warmer-looking. I don't know why they discontinued the battened trellis at the rear of this small garden. I like the way they've used evergreen climbers against the walls.
