Working with a concept created by architecture firm Pascall and Watson, Merson completed the construction design, manufacture and installation of a large monolith sign as part of Heathrow T5’s departure lounge upgrade. Featuring 6 integrated LCD screens and a lightbox holding store map layouts, plus the ability to house CCTV camera and Wi-Fi hubs, this monolith is a significant addition to Terminal 5’s wayfinding programme.
