Brown Boxes on "Strasse" lots?

[MattyFo]

I am getting brown boxes popping up all over my city.  I've done a quick STEX and LEX search, and have searched in google, But seeing as how strasse translates to road or street I have had little luck in finding the lots. 

The lots in-game names are:

Muttler Strasse
Noebert Strasse
Plamorder Strasse
Schmalzkompf Strasse
Gamorkopf Strasse
Kreurjoch Strasse

I'm guessing these are all from the same pack, I can only assume they are all low density houses, seeing as how they only grown in residential areas   Does anyone know what this pack is called or even what dependancy I may be missing?
