I had always wanted to do half frozen over harbour, with some precarious routes over the ice. at the time I found these really interesting photo's of this antarctic base/research center called Palmer Station.

I've never been to eastern europe, but I've seen some youtube craftsmen working in places with a very similar aesthetic. You can pull this off real easy with TC:E stock assets and without needing to do much custom modelling.
As another idea. I've also seen some really beautiful finnish industrial architecture, with tall white brick buildings, very tall windows, surrounded by dense birch woods. I stumbled upon that style by chance in a thrift store in Leeuwarden, where they sold these really rediculously priced architecture books. Can't help much further than that, but it was definitely a look that stuck with me, and I think the lead is worth investigating if you're out of ideas
