Thinking About Design For The IWW Office

I want it to look beautiful, and nicely designed and cool without having that “artsy coffee shop as harbinger of rent hike” vibe.

How do I say “Nothing’s too good for the working class”/”We’re not drab Stalinists”/”We’re not crust punks” in interior design?

Like I want it to be really nice, but also make people who are used to getting the stink eye in bougie coffee shops feel welcome, but also say “we are a bunch of industrious functional adults who care about our community”
