In 2005, Malkit Shoshan, along with Michiel Schwarz, Willem Velthoven, and Alwine van Heemstra, founded FAST (Foundation for Achieving Seamless Térritory), an alternative architectural practice that studies the relationships between architecture and realities on the ground in conflict areas such as Israel and Palestine, Afghanistan, and Kosovo.
Since then, Shoshan has advocated for the incorporation of a fourth ‘D’ in the criteria of the UN (Defense, Diplomacy, and Development) in its peacekeeping missions around the world by analyzing the impact of the joint mission of the Netherlands and the UN in Liberia and Mali.
