This beautiful spiral is a model of the walkway inside the Bloomberg European Headquarters that are currently being built in the City of London. Instead of individual flights of stairs between each level, this ramp seamlessly connects six floors of offices. The engineers based the form of the ramp on the shapes made by the Spirograph drawing toy! #spiral #model #London #engineers #architecture #vamEngineeringSeason @vamuseum
