There are quite a lot of blogs and articles about how to build your own in ground trampoline. Having not built one in oursleves we don't feel qualified to say any more on the topic other than many of our customers have done as this customer did and simply dug a hole, took care of the drainage, built a retainng wall the size of the trampoline frame and secured the frame to the retaining wall.

Other customers have built the hole but have simply placed the trampoline with its legs into the hole. (from reading the articles and blogs this is not as good - because the legs can sink into the dirt / stone screenings.

Another customer with a round trampoline made a retaining wall above the ground put the trampoline inside the retaining wall and then bought  a couple of loads of dirt then pushed it all up to the retaining wall and esentially made a hill in his back yard with the trampoline in the middle.

Hole prepared with drainage and retaining wall, Trampoline frame bolted to the top.
