The entire project is worth a look, but I was most struck by Avgust's redesign of not just the station, the signage and the surrounding area, but the subway car itself. It's freaking gorgeous.
Particularly the interior:
Avgust's use of color and restraint yield an interior design that is Spartan and functional, yet still reads as very elegant. I know using actual copper as depicted here would be impractically expensive, but ther material's antimicrobial properties would surely be desirable in this day and age.
