The colors of those renders make me think OpenSCAD.
I particularly like your railing and the screen wall next to the stairs. The bar cabinet has a neat design too, although I feel like it should be a little taller (counter height). As it is, it looks a little more like a TV stand, except for the rotating stemware storage part.
The house itself looks a little too vertical to me, but I guess it wouldn’t work very well as a dollhouse if it were a ranch. Maybe lean into the elevation changes and make it a split-level or put in a conversation pit?
















(Speaking as an early Millennial)
I have a gigantic cabinet in my dining room/kitchen (not much wall between them so it’s kinda the same space). It’s 8 feet tall, solid hardwood except for the glass doors, and was originally a built-in from a house in the next neighborhood over. They put it out on the curb and I saw it, hitched up my utility trailer, brought it home and installed it. Best curb find so far.
I use it as a pantry because my house small and doesn’t have a closet-style pantry.
I also have a set of fine china that a friend gave me as a wedding present (even though we didn’t have a gift registry), but the pattern isn’t really our style and I’ve never taken it out of the box. I don’t have plans to buy other fancy dishes, either. I’m very happy with my cheap Corelle (except for the fact that they discontinued the pattern and I wish I had more sets of it).
So, technically, I “have” both china and a china cabinet, but it is very much just a Boomer thing anyway.
