Dr Elisavet Hasa is a London-based architect, researcher, and educator. She holds a Master of Architecture degree from the University of Patras in Greece and a PhD in Architecture from the Royal College of Art.

She is a Lecturer in Architectural Design in the BA Architecture programme at London South Bank University, where she leads an undergraduate design studio and teaches dissertation modules. She is also a dissertation tutor at Central Saint Martins, University of the Arts London. Her work concentrates on the climate emergency, housing crisis, feminist ethics of care, social movements, and institutionalisation politics. Elisavet’s research draws from her empirical studies and participation in mutual aid and solidarity projects in Greece and abroad. Her work on these subjects has been published and presented internationally on various occasions. Her upcoming monograph, Building Solidarity Architectures: Collective Care in Times of Crisis (London: Goldsmiths Press, 2025), explores what one could call the "lived architecture" of everyday practical, immediate, and coping mechanisms of collective care based on her decade-long activism and volunteering with the solidarity movement in Greece.

She is a registered architect in the UK (ARB) and Greece (TCG) and has practised architecture in London, Madrid, and Athens. She co-founded Fatura Collaborative, an architecture and research practice with projects across various scales that address new issues about ecology, care, domesticity, everyday life, and the city.
