Original series
Bob (voiced by Neil Morrissey in the UK and by William Dufris in series 1 & 9 in the original series, Greg Proops in series 10 & 14 in Project: Built It and by Marc Silk in series 15 & 16 in Project: Built It and Ready, Steady, Build! in the US and by Lee Ingleby in the UK and by Colin Murdock in the US in the reboot series) is a general contractor and head of his own construction yard based in Bobsville and later in Sunflower Valley and now Fixham Harbour and then Spring City. Bob is from a family of builders – his father Robert is also a builder and so was his grandfather Billy. He is assisted by Wendy and a host of anthropomorphic vehicles in various projects in and around the town. He is the owner of Pilchard and he is not good with computers. Some of the problems in the show arise from Bob's habit of forgetting to turn his mobile phone on. His catchphrases are "Right, team, can we fix it?" in the original series and "Morning, team!" in Ready, Steady, Build! and "Can we build it?" in the reboot series. Wendy (voiced by Kate Harbour in the UK and by Lorelei King in the US in the original series, Project: Built It and Ready, Steady, Build! and by Joanne Froggatt in the reboot series) is Bob's business partner and best friend who runs the office and keeps the business in order, and often organizes tools and equipment. She is also seen doing construction work in many episodes. Wendy is often worried about Bob's cat, Pilchard, as shown in the episode "Pilchard in a Pickle" and in the song "Find That Cat".
Reboot series
Leo (voiced by Jacob Scipio in the UK and Daniel Bacon in the US) is a college student, Bob's apprentice and Curtis' son.
