Interesting pictures and ideas in both the article and the thread, thanks for sharing.
I always make the interior of buildings (although not always with many details) because I would feel very frustrated not to be able to enter the houses in RPG-ish skirmish games.
I tend to make the length and width of buildings slightly smaller than real, to gain space on the gaming table. But I also noticed that seen from above and with miniatures inside the interior often seems cramped although at real scale, it takes time to get used to it: real kitchens or bedrooms etc. in most houses are not large at all.
