After a while of only collecting Fabuland I also started making my own Fabuland buildings and scenes some years ago.
For a show I was asked to make an own creation on a 48x48 baseplate. Of course I wanted to make something Fabyuland style and also show various items from Fabuland as some houses, cars, a boat and of course different Fabuland figures. The result is in the image below.
Note that not all elements have been used in Fabuland sets (e.g. the fences), but I think the model has still a Fabuland style over it.
I myself was (and am) pretty content with the result and started to expand the city. I made several modules (each on a 48x48) baseplate, such that I can easily rearrange the modules to create a different look or to ft more easily to the table size on shows.
Below are 4 modules next to each other, but they can also be rearranged into a square or put into a corner.

Sybrand
