Participatory planning approaches are said to improve agreement on sustainable housing development objectives among stakeholders. The choice experiment method (CE) offers much potential for an in-depth and rigorous participatory planning approach, e.g. having individuals choose their most preferred option from a range of (planning) alternatives. Here we tested for differences in preferences for housing development alternatives resulting from the different forms of presentation of identical choice set information (treatments) - in particular, digitally generated film sequences presented to respondents as compared with the presentation in the format of a series of still images, as an internet survey among German home buyers. The findings suggest that a more sophisticated form of choice set presentation, 3D film sequences, was outperformed by a more basic form of visualisation technique, the choice set information presented as 3D still-images. Also, we tested for the effect of the degree of 'expertise' of respondents and found that a more sophisticated form of choice set presentation (3D film sequences) led to a better comprehension of the choice set task only among 'expert respondents', i.e. respondents who in the past had made a housing investment decision or were presently making an actual house buying decision.
