With shorter days and cold weather in the future for most of us, it's nice to know there is always some place that is warm and tropical out there. Now it can be in there too.... all you need is a couple of sticks, some rubber bands, a houseplant, and a little imagination!
Any large plant will work, as well as any "building material" that is long and narrow, from pencils to popsicle sticks. You can make a plan, or just start tying sticks to the plant and see what comes out! If the floorboards or roof are slipping around too much you can always employ the age-old fix-all...hot glue. Just make sure you don't glue anything to the actual plant. Whatever your construction style, a houseplant tree-house is a great indoor project for parents and kids that makes any corner into a micro climate of endless imaginative play.
