In 2014, the UCL Faculty of Engineering Sciences introduced the Integrated Engineering Programme -- a revision of eight existing degree programmes across a range of engineering disciplines. Centred on a thread of authentic project-based activities, the programme aimed to enhance the students' understanding of key theoretical concepts and heighten the development of key professional skills. This paper provides an outline of the rationale for the various project-based activities implemented, details their key features and described the impact these activities have had on the students' development of key skills.
