This article demonstrates the interdisciplinary and transdisciplinary approach to peace by involving diverse thinkers’ creativity, knowledge, and the arts co-production process in the practice of science itself. It is an attempt to blend theory and practice together for a better understanding and addressing the under studied gap between macro level planning, decision making and the micro ground level work done and impact within the field of peace, sustainability and architecture. The article introduces a new transformative approach, New Peace Architecture and Peace building, through three case studies that brings concepts of sustainability and peace together which no longer bifurcates between human, non-human, living and non-living organisms in the practice of everyday building. In this transformative approach towards an open society aims to address intercultural and interreligious dialogue on the axis of a sustainable and just future, to strengthen women, to change consumption behaviours accordingly, to organise unusual collaborations between diverse actors, to implement nonviolent sustainable and just ideas in the city.
