Today's House Guest is Frieda Gormley, co-founder of House of Hackney. Frieda set up the luxury interiors brand 13 years ago with her husband, Javvy M Royle, and the pair quickly ripped up the rulebook, reworking traditional print and colour for a new generation. Carole Annett chats to Frieda about creating heirloom pieces and developing a regenerative brand.
