If this post was interesting to you check my architectural models blog[0]. It’s in zombie mode now but I posted regularly for a decade.

Some of the models contain a rail segment (Märklin etc.). Was he a model train enthousiast and the houses were part of a layout, or did he use the rails just as accessories? Strange that the articles don't say anything about the artist's motivation.
Czechs have a good tradition in paper models of architecture:

https://en.wikipedia.org/wiki/Richard_Vy%C5%A1kovsk%C3%BD (sadly the article doesn't really do justice to how prolific he was, partial list of models is https://cs.wikipedia.org/wiki/Seznam_vyst%C5%99ihov%C3%A1nek...)

I only found out relatively recently his models are life size.
