In May 1994, the Tate Gallery in London decided to build a major modern art gallery by converting a disused power station. They controversially chose a small Swiss architectural firm over established London firms. Karl Sabbagh documents the project from its beginnings to its opening, following the team as they navigate design, construction, and art-related challenges, alongside internal conflicts. Sabbagh recounts the story of this rare success in public design, detailing setbacks like delays, a flawed staircase, asbestos issues, and changes in management.
