Okay, so!
I wish to propose a sort of challenge/theme since even if you have to go out into the world things have gotten a little nuts lately and having something to focus on never hurts.
A house is a bit much for most of us to pull out of thin air, so my suggestion is we do a sort of challenge/craftalong within a craftalong with a theme along the lines of “Happy Places” or “Joy” or something to that effect. My idea is that we could each start a roombox, or a whole house if you have one, or repurpose one of those wee kits and use mostly whatever we have at home since we’re meant to be socially distancing.
Scale, size, details are up to each individual. You can make more than one, of course. You could make a whole room of tiny plants if that’s what brings you joy, no judgement 
Inspo from here: make a house for a mouse. I got this email a day or two ago and I thought it was PERFECT for all of us! Plus Ann has a bunch of free tutorials on how to make stuff like miniature cups and plates, a miniature rug, a doll bed from clothes pegs, a miniature quilt to go with it, a miniature stone hearth, a tiny bicorn hat, a tiny top hat and even a free pattern for the wee mice that she made a home for in the recent post.
Use any somewhat sturdy box you can get your hands on or make one, or even just make a scene out of a floor and a back and/or sidewall.
