These rather solid and chunky resin buildings come from Fogou Models, they recently had a sale on as these structures are a bit on the pricey side normally. They are listed as 28mm but most of my 28mm stuff towers over these, I think 25mm is a closer fit, still they are nicely detailed and solid.
I love these new miniatures, although I didn't stray from the instructions in the starter set, my next box I buy will be outfitted the way I want. Until I think of a better name, the Outland Vixens are what I', going with,
I found these two in a 2nd hand bin, I personally feel the Street Violence miniatures line has some of the nicest modern/post apoc minis out there, and they do tend to turn up quite cheaply these days.
