The £14m Royal Court, scraped back to raw masonry, concrete, and iron, with its congenial leather benches and vibrant red foyers by artist Antoni Malinowski, started Haworth Tompkins off on a grand tour of alternative theatre. Subsequently they designed the Almeida's two temporary homes, in an old bus depot at King's Cross and at Hitchcock's old Gainsborough Studios in the East End - both done for just £700,000 each. Then came a thoughtful £2m reworking of the Regent's Park Open Air theatre. Apart from the Young Vic, Tompkins is now working on the 1950s theatrical research lab of the National Theatre Studio in Waterloo and - a particular favourite - the new, tiny £2m Egg children's theatre, opening in 2004 for the Theatre Royal in Bath. To round things off, he has also been chosen to redesign the Theatre Museum in Covent Garden, an outpost of the Victoria and Albert Museum.
