Can SketchUp do any of this?
Also Blender lacks support for exact measurements AFAIK.
I tried this approach but gave up after barely achieving a rough floor plan after a day's of work.
I often draft the floorplan in AutoCAD first, bring that into Blender...
But the results are amazing. I wonder if a powerful but easy interface could be built as a bridge /plugin for these tools.
I had fun drawing 2D house plans. Eventually I discovered through randomly clicking around that there was a button where you could place a camera anywhere and VIEW YOUR HOUSE IN 3D. Incredible. I didn't even own a 3D videogame at that point. The house and all its furniture were untextured but you could select the paint colour.
Look like they still exist[1] and have a consumer-targeted version now as well, called Home Designer.[2] I have no idea whether it's any good.

There's a whole category of such software, it's called CAD. The professional products are notoriously expensive.
As an architect I can confirm that there's indeed a lot of professional software for this. The ones I usually work in are Revit and ArchiCAD, which are tailored for architects. Our interior architects also use Sketchup a lot. There's also more general-purpose CAD software like AutoCAD and Vectorworks available.
Found https://pcon-planner.com/en/?privat=530&page=126 instead which is windows only and bon-open source but effectively free.
Pretty impressive stuff. Been very happy so far.
I was pretty happy with this for whatever project I was doing at the time. I recently started using inkscape, just to have a general purpose drawing of my house. There, it can include raster maps, layers with other kinds of information like a circuit map, etc.
It just seems like a "whole-house visual diagram" software tool should exist.
