    Pond wall dilemma

    I first set about this pond build as a bit of a budget diy job in the hope I could do it fairly cheaply and I’d end up with a reasonable pond, having spent hours researching it’s become obvious that’s not really an option, you need to do it right and it costs what it costs.
    Now onto the walls, my original plan was a timber frame, ply lined, decking clad job, box liner, nice and easy, after years doing concrete forming using timber shuttering I was very confident I could build it so it didn’t move a millimetre when filled with water but it’s now a different job I’ve had to raise the level of the pond after hitting solid rock in the bottom, easy enough to do but the downside is, at this height you won’t see the surface of the pond when sat on the decking patio, which sort of defeats the object of the exersize, now the answer to this is a window in the side giving hopefully a good view of the fish from the decking as well as the lounge and they look nice as well to boot, so all’s good.
    the dilemma is the wall construction to take this window which at the mo is 1800x400 deep, so quite a long span in what is already the longest wall of the pond.
    structurally the obvious is 100mm dense blocks laid on their backs to create a very strong 9” wall, these will be rendered on the outside with some sort of capping to finish it off, the problem being to make it look a finished job you want the same width coping all round the pond meaning a 9” wall on all sides that’s a hell of a lot of blocks as well as time and money but the real issue is, it’ll reduce the volume of the pond by quite a sizeable amount, I’ve no option to push the walls out to retain the same size pond becuase of the garage and footpath so I’m a bit flummoxed at the minute, considering 6” dense blocks as an option but will they make a strong enough wall for that glass panel? I don’t know, open to any suggestions or thoughts please

    The dug out area which is garage wall to footpath and max length I could get due to power supply going to the garage is, 3.9 down the garage wall 2.3 at it’s widest point narrowing to 1.1 obviously it’s triangular in shape, depth wise depending where you dip it I’ve got 1.3, having now hit solid rock it does fluctuate a bit but I can certainly get a finished depth of 1.2 this deepens at the BD by .1+ to create a fall to the drain, this just happened to be the levels once it was all cleaned out, the concrete really is just to provide a level base to build off as I say we’re already on solid stone, where the footpath is at its lowest there will be around .6 of pond wall showing above ground

    My first thoughts were 4” block down the garage side and across the top back filling with concrete at this top end as each coarse was laid, the bottom end nearest the camera, I shall be building some concrete steps that will span the footpath and pond so this end is no problem, it’s what I do down this left hand side that will take the window?
    and how do I make it look right once built and lined around the top?
    obvioulsy going with block work the internal dimensions will be reduced further by either render or some form of insulation board before I fibreglass.
