Our apartment was once described by a friend as “cozy postapocalyptic”. My SO collects plants and has filled the place with a couple hundred at this point. Plants cover some tables, spiderplants and pitcher plants cascade from our refrigerator and high shelves. That, combined with our tendency to pot them in whatever old containers fit, from buckets, to cans, to take-out dishes, probably set some of the ‘reclaimed by nature’ tone. The rest is in the way we get our furniture - about half nice old antiques we found on trash day and fixed up, and half old office furniture with modern that industrial look. It clashes a little bit it’s all mixed into comfortable clutter so I don’t think it looks bad. We’re just not really magazine-cover, house-with-a-theme people. Neither of us has bought furniture new in years, though we sometimes make it from scratch out of secondhand lumber.
