    the hole is the old pond.
    i have 4 5 inch comets keeping some of my bio filtration alive for me.
    I plan on bracing with diagonal 2x4s and i think im going to finish it out with cedar, and build a bar off the end on the concrete the stool seems to be at the perfect height. This is going to be covered with a breezeway im building from the house to the shop.

    you may need to brace it with more than 2x4s
    Steve/birdman has some like this you may want to check his builds

    im going to tie the headers to the toe plate which are both 4x6's its going to be plenty strong and its going to get plywood staples to every stud the thing is going to be tank. Im a contractor I do this for my second job for a living. Plus im a firefighter on LATF6 structural collapse team I deal with woodframe loads all the time. Just got back from Tuscalousa Alabama from the hurricane a few weeks ago.

    nice to meet you.
    seems you know your stuff.
    its just I had seen some buckle that folks thought they built strong, but the water was heavier than they had bargained for....

    you will find some wonderful koi at Purdin! remember to share them here too!

    sorry
    i do not have confidence in it to hold up.
    course what do i know.
    using 4X6 or 12X12 or even 1X1 looks like you are depending on the nails to hold more then the boards themselves.
    when in hurricane area what did more damage the wind or the pounding water.your water will be suppling pressure 24/7 and trying to escape to the air on other side.
    this structure you could place a HUGE fish tank on the top and it will hold the water in the air.i just do not see this structure holding the pressure in.
    so i say GOOD LUCK and do some searches also

    The problem you might have will be the pressure at the bottom of the "studs" you put in. The outward force is tremendous, most at the corners. Really thick plywood (1" ply) will help spread that force onto the bottom laying beam but the vertical studs concern me.

    I went with a horizontal strapping of 2X6 like this - Pond

    2 yrs now and it hasn't budged an inch.

    Also, consider in your design the ability to install a bottom drain. The whole thing needs to be raised up to allow plumbing underneath unless you can dig...
