Moss. Preferably the thick dense dark green kind of moss that looks like a carpet that grows on the north side of embankments where little sun reaches. How close is your nearest state or national forest or, in the alternative, the nearest dirt road with an embankment that gets little if any sun because of shade trees. Take a drive and/or walk and see what kinds of moss you can find and take some pics. A dozen or so pieces would likely be all you need to get it started because, with the right conditions -- shade and moisture -- it spreads. (Ferns like shade but usually do better with drainage. Moss likes damp but will not grow in a puddle.) Where you have windows, you could create a "view" : With a concrete planter (or on concrete pavers set a large clay planter) with a trellis with English ivy. Alternately, you could buy your own pieces of exterior grade plywood and use deck screws to affix them to the fence posts and horizontal supports of the fence and decorate them w/paint and/or planters and/or metal sculpted art --- get creative.

Oh wow, it looks fantastic! The black looks so striking against the white, not too sharp at all. Congratulations on the house, you must be very excited to move in. :)

Pressed metal splashbacks are so rare! This is the first photo I've seen with a splashback like this and I'm really enjoying it.

Unfortunately it is also a requirement in the CCC District plan restricting ones fence height being over 1.8m. There are also stipulations about visibility of no more than 50% through the fencing so most home owners opt for the cheap solid timber fence. It is rather frustrating when we design these beautiful homes and the client has no regard for landscaping and the house is subsequently 'blocked from view.' Perhaps a little more client education would go along way for us to push some great landscaping designs and make more of a house on a section.
