That screenshot looks on the one hand very useful and on the other hand somewhat user-hostile since you have to build your own mental mapping from the architectural-style floor plan to the rooms in your house without any hints - I can imagine it being much easier to get used to or share with guests if there were sufficient icons or furniture shown in each room to make it obvious which room it is and which direction it's facing without having to consider the measurements and position relative to the other rooms.

I have to disagree a bit. For new users it will always take a bit of time to get used to it - be it in 2D or 3D. But after some time, the usability of 2D and 3D will be the same. And guests will have that problem either way - for that reason, one could just render their usable rooms on a separate UI.

If I were to use the 2d floor plan I’d look at it for a moment, and then I’d flip a couple of lights so that I could tell which room is which. It’s not complicated imo.
