Primer B mailbox has been developed in response to two needs: the decreasing use of the mailbox as the primary mail and a manifest lack of communication in certain everyday situations. Through the concept of a mix between mailbox and library, this design offers a second use as a container of pocket books. At the same time, primer B improves the neighbouring participation by means of reading,opting for a sustainable design that shows values such as cooperation and education.
First B consists of two functional parts: a translucent one in which each neighbour can leave the books he wants to share and a second one where the exchange of these books is held. Formally evoking a bookstore, Primer B combines aesthetics and socially sustainable design in a place sometimes forgotten.
