This response action works to turn given city surfaces into open exhibition spaces . It is a cost effective merged model. Design of spatial management models have the potential: a) to reduce maintenance and cleaning costs for local authorities, b) to provide physical spaces that can be self-managed and/or community managed, and c) to drive collaboration and engagement between various stakeholders.

Organised well, authorised spaces have the benefit of allowing diverse members of communities to apply their different skills to a single space as a form of ‘street gallery’, while commissioned spaces provide enterprise opportunities for local aspirational artists and helps establish a level of quality. Locally focused competitions bring independent artists and creative practitioners to add vitality to urban, rail and other infrastructure environments, with dynamic (changeable) elements of visual surprise and creativity.

The “Open Walls” initiative in Spain is a good example for this response action. The initiative allows anonymous permissions granted via an online website where anyone can subscribe to and use a designated wall for painting murals. All the walls used for the project are public walls, found by Difusor (a public-private cultural entity, non profit arts organisation) and “authorised” by the different boroughs where Difusor operates the project.
