Orange cube

This guide to the Orange cube in Lyon follows architects Dominique Jakob and Brendan Macfarlane's decision to punch an oval void straight through the middle of an office block on the old Lyon docks, and the design review where they had to defend it. You'll hear how workers moving in back in 2011 reacted to their new sunlit crater, and what the void's odd shape turned out to be for once people actually started using the building. It traces the perforated orange skin from unloved punchline to something people notice from across the river.
