We have not wet tested the maxxus yet but would like to have a deck built off of our house 42" off the ground so that we can enter it from our house without having to install steps.
I recently got an estimate for the deck and a 17' x 24' Betterliving 4 season sunroom, the spa would sit in the middle of the sunroom a couple of feet from the wall that would be 24' out from our house.
When I told one of my son-in-laws who is an engineer about our plans, he didn't think it was a good idea because of the weight of the spa. He thought it would be a better idea to build a retaining wall around where the spa would sit, and have that filled with material and then pour a concrete slab for the spa to sit on. The deck would then be built around this area for the sunroom to sit on.
We live in north central Minnesota so frost is a problem, and the footings would have to be 4 to 5' deep.
What would you recommend? I think his idea is a good one and at 42" an end dump should be able to dump material over the wall with no problem.
