I've been given the task of updating a pond, trouble is it's a tricky one as it's placed strangly and doesn't have much edge to begin with. Hopefully the pictures will help. The pond is built into a wall sort of. The base is concrete and there is not an opportunity to lay pond lining as there is no edge to lay it on to then put slabs or brick work over it to keep it in place.
At the moment it is filled with pots and there is a little bit of water in it where the rain settles but it somehow seems to empty itself, perhaps evaporation.
That looks like a problem waiting to happen. If it were me, I would place a space between the wall and the bricks and put some kind of drainage there. Build a second wall, batten it away from the bricks to breathe, and attach the liner to that.
I suppose you could use a spray-on or paint-on liner, but I wouldn't do that for someone else where I warranteed the work.

Yes Mr.Scott it's a bit of a puzzle. It has been working as a pond but with a pump but the lady's husband has died and now she wants it less formal and more wildlife orientated. The pond doesn't go up the wall it's quite low. Once the pots are taken out it's quite shallow it's just there is no room for adding shelves or anything like that. I had thought of taking some of the gray bricks off and using what's left to plant up into, giving some coverage and protection at least.
I was also going to attach a drain pipe to the shed that is near the pond and then run another piece of pipe into the pond to keep it topped up. hopefully I'll have a better idea of what to do with it once the pots have been removed. They are only there as there is no water in it.
I do like your idea trouble is I can't do brick work so my skills are limited, not sure if I can even do anything with this pond.
I’ve taken some more photos of the pond. I have a few ideas of what I might do. I was going to place the shell shape on top of existing rocks/stones but lower into the pond.
Then surround this with tall skinny looking pond plants. Then shingle all the way up to the shallow end but think the shingle might slip down the deep end and look awful. The idea is that the majority of the water is at the deep end rather than filing the pond.
I am worried any plants placed directly into the pond will crack the pond base which is made from concrete.
