The 2008 recession has driven the need for social and economic change in Athens. Out of this negative legacy emerged the solidarity initiatives of the Sharing Economy. In a city where inhabitants were now time-rich but economically poor, these programs provided alternative trading methods. How could this economic change impact urban proxemics? How do architects design for a city in transition? My proposal explores in detail one form of alternative currency that gained popularity post-recession - the Time Bank. Time Banks trade in hours, allowing users to exchange their skills. I focus on the work of the Athens Time Exchange which currently hosts trades online. In my proposal I create offices, facilities and a co-housing centre for this organisation within an abandoned structure: the former headquarters of the IKA Pension Organisation. This micro-city proposal acts as the node of my masterplan, which includes a communal greenhouse and cooking school.
