Matt graduated from the Motley Theatre design course in 1994 and spent the next decade working at the National Theatre in London as a designer, design associate and draughtsman. Matt left to work within commercial theatre, developing many large productions and adapting them for tour. As part of a long working partnership with Cameron Mackintosh, Matt initially adapted the original versions of My Fair Lady and Mary Poppins as well as co-designing the recent international productions of Miss Saigon.
In 2009, he was invited to redesign Les Misérables for its 25th anniversary production as a UK tour. The success of the new staging has seen subsequent productions and tours across the world, alongside presentations on Broadway and the new West End show at the Sondheim.
Matt also designed the 25th anniversary concerts of Les Misérables at the O2 Arena and The Phantom of the Opera at the Royal Albert Hall, as well as the recent Les Mis concert at the Gielgud. Matt also designs a wide variety and scale of productions, both in the UK and internationally, with a long history of developing large-scale musical theatre in São Paulo, Brazil.
