I don't think that it is so much the wall that is the problem but the plants hanging over the wall. They are leaning on the wall and look as though they may be destabilising the whole wall to the point that it may fall over. If you removed all of the top heavy plants on the inside and then had a simple hedge that is a bit higher than the wall itself so that you get a solid green above the wall, then this green would break up the monotony of the wall. Keeping the weeds away from the base of the wall would also help, tho this is not too bad. You could paint the lattice but once you do this you have ongoing maintenance. You could paint it a bright, bold marine blue or yellow based red/orange, but as stated, the maintenance is then ongoing. I would look at the structure of the wall to ensure that it is stable before doing anything. Alison

I'd find some exposed aggregate and test the foot friendliness yourself. I don't think it would be too bad. Is it going to be used constantly by people in bare feet?

After rendering our house in Dulux Western Myall (dark grey) with Surfmist trim (and a pop of colour with Haymes Golden Delicious) we loved the colour combination but wondered what to do with our beige roller door. Not being ready to replace it, we scrubbed it, lightly sanded it and painted it Western Myall. It was quick and easy to paint it situ and OMG the difference was stunning. Looks like new and has moved the "garage door situation" to the bottom of our list now.

Nice work! It's gorgeous and looks a lot more friendly.
