Bushy lavender plants behind a sitting wall is a lovely combination. The lavender is planted about a foot away from the wall so it won't interfere with seating...and by interfere, I mean these plants are quite an attraction for bees. A little distance lets the bees do their thing and the sitter do his/her thing. In such a large planting the scent permeates the air.
The hanging basket adds a little height variance to frame the scene. Posting this as a future idea for the garden.
