The idea for the design-bus ‘Oscar’ was born in succession of a number of commissions that lehner en gunther architecten was granted for the design of public space. The projects are aimed to redesign the public space in a number of streets and entire quarters. The architects refused to work on the projects from their offices, but invited the inhabitants to work together on site. With the tool of the design-bus ‘Oscar’ the people can easily inform the architects about their ideas and at the same time see the development of the design for their own neighbourhood
