Yasmeen Lari is Pakistan’s first female architect and one of the most successful providers of disaster relief shelters in the world. She has built more than 36,000 houses for victims of floods and earthquakes in Pakistan since 2010. Shunning the structurally weak, mass-produced houses offered by international organisations, Lari uses vernacular techniques and local materials such as lime and bamboo. Her houses have a tiny carbon footprint and are simple enough for people to build themselves. With this, she hopes to demonstrate the role that architecture can play in humanitarian aid.
