Lighting has evolved from a functional necessity into one of the most expressive tools in the interior designer's palette. With intelligent fixtures, light can now shift in colour, temperature and intensity throughout the day, warming mornings, energising afternoons, and creating cinematic evenings, all tuned to how we actually live. It can transform art, sculpture and materials within the home, add layers and drama, quietly shaping mood, emotion and experience. How are interior designers and lighting specialists working together to use light and shade in new and exciting ways? How could we see these ideas in action at WOW!house 2026 and what is the likely impact of such creative, design sensitive collaborations on the future of luxury residential design? Host Jeff Hayward is joined by WOW!house 2026 room designer, Samantha Bartlett, Luke Thomas from John Cullen Lighting, James Ratcliffe from Homeplay and Shaun Gumbs from Lutron in front of a live audience of designers to find out. This episode was recorded at the Design Club in the Design Centre Chelsea Harbour. Our thanks to our partners, Lutron, and to the Design Centre for their support. The interior design business is a Wildwood Plus production.
