C-Section is a design consultancy in Istanbul, Turkey whose offices have a dark bunker like appearance. Its not clear if the photos have been doctored to look dark, or if the shots were taken at night, or if they are really underground!
I think the wood floor is a give away that this is not really a converted parking garage. There are video games and plenty of light fixtures so I'm not sure why the dim lighting. If it was part of the design concept for the space I'd sure like to hear more about it and how it affects the work environment.
I see some big table desking going on there, but its too dark to id the tables or the task chairs for that matter.
