Back to school

Started the day with a meeting here - no longer a school, but a rabbit warren of serviced offices. The building's jam-packed with all manner of different companies in eccentrically-shaped offices that still look like old classrooms.

The most remarkable thing about the building is the two mind-boggling staircases that lead in completely opposite directions to your expectations. You find yourself trotting confidently up one staircase, only to see that the landing you're trying to get to is reached by the other one. And no matter how many times this happens to you, you never learn. What kind of school is that?
