Back before ladders were used to build goza floors, people were already doing it with a table, and stacked items, and then a particular type of book on top. The goza targeted the book to place. Anyone remember what type of book(s) were used? I am trying to add a goza roof onto my magincia home - but the land seems to be high enough that when I am on the 4th floor - I can not climb a ladder - though I can raise the mats and use a goza-stair to climb up - but the highest level that I can raise the mats to is not high enough to walk under. I am hoping that I can raise the mats as high as they can go - then use the table and book to place a roof that is high enough. Any info or suggestions would be appreciated.
