The thing about my 22 month old DD is that dumping objects out and moving them around IS the play. We have a lot of baskets and drawers for her toys and I move things in and out about once a week to keep it interesting. I tell her that I'm cleaning and she follows right along throwing toys into bins and boxes.
Our living room and bedroom is 100 percent friendly and safe to her, well unless you count her overuse of gravity. If i need to cook and she is in a good mood I just let her go and keep her in my sightline every couple of minutes. She dumps out blocks and steps on them, stacks them and if I'm lucky she'll throw them back in the container it came from. But most of the time she wanders off into something else and I follow along later and scoop things up.
We have stuffed animals stashed in fun places, cabinets with some basic toys, books on the coffee table, some hats and play shoes, and a bucket full of balls. Between that and the cats she just bops around putting her little animals on things and mixing objects randomly to amuse herself.
But yah, she makes a total mess. I'm not sure what you mean by "destroy" but I will comment that if she rips a book or breaks a toy I take it out of her area for repair or toss it if it is beyond mending. I don't like for her to get the idea that it is OK to rip up a book or be harsh with delicate objects.
I try to keep things in the main floor area tidy but it doesn't always happen. I tidy up before her nap and DH does a complete Roomba pre-clean after she goes to sleep at night. Once everything has a home it is easier for DD to put things back but she doesn't always do it.
