This is definitely a small garden courtyard, rougly 3x2mt.   The main view from the living area includes a cat run and a small courtyard to sit and catch some sun.  We made the most of the existing plants, a couple of established Camellias, 2 standard Melaleucas, and, then added our clients preferred plants, Grevilleas and Tree Ferns.  This is a north west facing aspect with busy paths right outside the courtyard, so our favorite small space tree, Crepe Myrtle was used to create a light canopy, both for privacy and protection.  The cat run now sits within a larger jungle.  Native climbers will give a soft cover to the frames, tree ferns for volume (Cyathea as it will cope with the conditions) and, bamboo for some vertical elements and screening.
