We have been increasingly using working models as a tool for designing and discussing urban form on most of our urban design and planning projects. The resulting built environments have, we believe, benefited hugely from this design process. Participants readily ‘read’ the models and engage in modifications far more readily than with drawings. Working models certainly generate unexpected design outcomes which are often more in tune with the genius loci of a place than always working from large area to small places, which is the opposite of organic growth. Above all, the models enable meaningful exchanges between all parties, often without recourse to words.
