Not often. Sometimes we will acquire a new piece that will necessitate some kind of rearrangement in a particular room. But mostly has remained as we originally configured it when we moved here over seven years ago.
The major pieces stay where they are forever. The smaller things like plant stands get moved if I add to lose a plant. My bedroom furniture weighs a ton and I haven't moved it in more than 30 years.
Maybe once every three months. I get bored easily and I like to redecorate. It’s just a pain because I have dozens of plants that need light so I have to keep shelving near the windows
