Brief. Creation of an ephemeral space for the interaction of participants at OFFF Porto 2015 festival, and between them and the city. The space to create should also 'announce' the occupation of Batalha Cinema by this festival.

Concept. This intervention combines vegetation with prefabricated metallic structures – public space as a dockyard and laboratory of ideas and social experiences. The dialog between both produces a space of contrasts – the organicity of vegetation is faced to the depuration of the metallic structure. Organic and artificial are not antonyms but subsidiary and actual resources for bioclimatic design. The components are assembled in a 'crude' way.The type, quantity and positioning of vegetation were thought in order to control the potentially negative action of NW wind. Because October is a transition month, the vegetation was thought to create different gradients of shade in order to allow people to find their thermal comfort conditions – 'adaptive capacity'.
