In the video, Baker talks about the planning that went into the experience and how she and her team came up with the concept.
The agency has been working on Cadbury’s Olympic projects since 2009, and got the brief for Cadbury House just before Christmas last year.
They moved to Hyde Park on 18 July to start the build, timing the opening of the house with the opening ceremony of the Olympic Games on Friday 27 July.
Baker said the feedback from the public has been "absolutely phenomenal". The house marks the culmination of two years of Cadbury’s sponsorship of the London 2012 Games.
