This is another reason for using different Names. You have Workhouses, so you have a House/Building where you can produce something. And you have House/Building for your town scene. When you look through our maps, you see some Maps with playing with a foreign culture like Byzanth.(for example: "saracen tent 03" for "Näherei 1" or "Frank church" for "Näherei 2").
So you have on playing a map towns with a byzanth-, saracen- or egypt-looking. It is no need to know, what other cultures do in there houses. But when you play with a foreign culture or you want a other looking town, you take the foreign buildings. Then you have to known, what building is it.
I hope you understand.
When I want a nice 'marketplace' in my landscape, i take the saracen tents. When I need a Sewery, I have to look for Buildings with 'Näherei ...'
