While, as the story posted Thursday demonstrates, there are other branches of the Aunt Family, a large part of the story takes place in one particular branch, and in their neighborhood - and that Aunt house.
There is no floor plan to the Aunt House and there may never be. But it has a feel to it.
Something like this (source).
And kinda like this. (source) It’s a bit out of place in the neighborhood, where many of the other houses are farmhouses or later-built ranches, but it also seems, paired with its own set of barns, to fit in. Perched on a corner intersection, it seems to hold court for the neighboring houses.
Also, while I was looking, I found this - https://www.thevintagenews.com/2018/04/06/steampunk-victorian-house-2-2/ - a steampunk house on wheels.
And I also found these:
which, yes, are Minecraft Victorian houses.
And this, which is actually decently close
A miniature Victorian house kit.
