Bricks
Breeze blocks are back, so sayeth Brickworks... Love em, but for outdoor rooms that see humans for more than two months a year, one needs to be in Mildura or up and they will need a pressure washer to maintain if outdoors and a maid who is not prone to RSI indoors, although I guess one could spray them with Mortein surface and hope for the best.
If one ever lived in Qld or the desert, the idea of a brick screen like this one is great. Halves or more the light/heat coming through and makes a gorgeous pattern in the room. Just be sure to consider what the pattern will look like with the furnishings - looks great here with plain/pale, but if one had eclectic jewel throws everywhere it could be epilepsy inducing.
