So i'am going to be moving into a new rental house that has a concrete backyard. Not necessarily a bad thing when you have dogs except for the fact that its facing west so it gets toasty! I want to build a freestanding pergola but i dont want to trash the concrete by drilling or cutting into it. And my landlord will not be happy about that. So i was thinking what if i build it and just let it sit there without anchoring it? Anyone ever done this? Im in california so its not hurricane wind area. Just dont want the ting taking off on me.
