CONCRETE OFFICE®

Posters are Arguments. Not wallpaper.

Six people, one long table, a risograph that hates Mondays.

Concrete Office is a graphic design studio on the Van Vollenhovenstraat, Rotterdam. Since 2011 we have made posters, exhibition identities and printed matter for museums, festivals and anyone with something worth shouting.

Manifesto

.txt
  1. # MANIFESTO v4.2 — Concrete Office, Rotterdam
  2. # read aloud on the first Monday of every month
  4. 01. A poster is not decoration. It is a public argument
  5. glued to a wall at 3am, in the rain.
  6. 02. We do not do "clean". Clean is what you call it
  7. when nobody in the room had an opinion.
  8. 03. The grid is a tool, not a cage. We show you the bars
  9. so you can see exactly where we broke them.
  10. 04. One typeface per idea. Three if the idea is loud.
  11. 05. We print what we design. If it can't survive
  12. a risograph, it won't survive the street.
  13. 06. No stock photos. No mood boards made of other
  14. people's work. No "can the logo be bigger".
  15. 07. Six people. One table. Everybody sets type.
  16. 08. This city was bombed flat in 1940 and rebuilt in concrete.
  17. We take that personally.
  18. 09. If the client is comfortable, we haven't started yet.
  19. 10. Finished beats polished.
  20. Honest beats finished.
