An architect and urbanist, Lucia has been working with Context since 2012. The emphasis of her walks lies in present Berlin from where she leads an exploration into the layers of the past in order to understand the transformations of the city and the significance of its sites, so as to anticipate possible future scenarios. Her thematic focus is on post-war history, urbanism and architectural heritage, as well as on everyday life in Berlin.  Parallel to her work with Context, she has been collecting experiences from different branches: collaborating with several public institutions analysing and comparing the urban landscape of various European cities, developing city guides and organising workshops; working for a design agency specialised in real estate and signage design; and currently, planning housing and office buildings in Berlin with a private project developer. She is a proud ambassador of Berlin and Context.
