The Dengineers is a British children's television series which airs on CBBC and sees the production team (styled as 'dengineers') design themed dens or play houses for children. There have been seven series aired to date, with the most recent hosted by Meryl Fernandes and Joe Swash and previous hosts being Lauren Layfield, Mark Wright and Joe Tracini. The designers are currently Tony Broomhead, Satwinder Samra, Maral Tulip, Emma Kosh, Anthony Devine, Lynsey Ford, Martin Bell, Sahiba Chadha and formerly Dee Saigal, Sege Rosella and Olga Skumial. The series is similar to DIY SOS and Grand Designs, with the help of expert designers and builders and the youngsters themselves, the Dengineers team will then construct an extraordinary den, either completely from scratch or by transforming an existing room in the home. Each episode is themed, with designs such as an old-fashioned railway station, a 1960s American diner and an Australian outback shack.
