So, I'm faced with moving one of these behemoths, which the previous owners left behind for us, and the wife wants in a different spot in the yard. I'm taking the opportunity to replace some damaged components, re-stain, etc., but with regard to preparing the new site, I'm finding very little (actually nothing!) information. It would almost appear folks are just setting these things right on the grass, with no piers, footings, etc. Looking under mine (I have not moved it yet), it appears the six cedar 4x4 posts which make up the legs of the main part, are sitting atop 4x4 pressure treated pilings driven into the ground. It seems to me that if I just set it on the lawn, particularly an area that tends to get wet this time of year, it's going to slowly sink, and perhaps list (it's much taller than it is deep). The actual move won't be much of a problem for me, but I am confused about site prep. I do want to avoid creating a large gravel or mulch area, and would prefer piers sunk directly in the lawn, if any structure at all is required. Opinions? Experience?
