If you have encountered an eye-catching billboard in a UK city in the past few years, it’s likely that BuildHollywood had a hand in it. There have been multi-layered displays that pop out of the frame, like those showcasing Ezra Collective’s album and the Wicked film soundtrack.

Other builds have made clever use of lighting and perspective, as seen with Coldplay’s Moon Music promotion, which used protruding letters to cast the album name onto the billboard in dramatic shadows. And there have been plenty of interactive moments for the likes of Jean Paul Gaultier, which allowed passers-by to stick on or tear off items like fragrance and skincare samples.

Long before it began making complex billboards and outdoor installations for just about every brand, band and artist worth their salt, BuildHollywood was founder Tim Horrox’s community arts initiative, which he ran in partnership with the Inner London Education Authority (ILEA). Huge numbers of unemployed people came and went through the doors of its base, an empty school on London’s King’s Road, where they tried their hand at acting, set building and staging small theatre shows.
