In 2002 Webster famously collaborated with Sir David Adjaye – one of the world's most imaginative and sought-after architects. The Dirty House in Shoreditch, was the first of two distinctive and ambitious residential projects realised together. More recently they saved the ultimate structure-with-a-story, taking the infamous Mole Man of Hackney's derelict ruin and transforming it into a bespoke home and studio which won best London dwelling in the 2021 New London Architecture Awards.
Webster published her second visual biography I Was a Teenage Banshee in 2019. A Künstlerroman (artist's coming of age novel), the book combines personal memoir with a visual narrative of her evolution as an artist, and describes how listening to Siouxsie and the Banshees helped guide her through a troubled adolescence. Webster’s most recent body of work Full Leather Jackets (2019-2021) continues her exploration of the bands ongoing influence on her life and work.
