Thinking and designing for future problems is great but also solving and building for present issues is important. The idea of building one in one is for neglected communities as they affecting the most and facing difficulties in vulnerable situations due to climate change, heat, flooding, inflation, space constraint, land costs and more. Idea of building 1:1 is started by Thinking Hand NGO in collaboration with studio Ketham’s Atelier Architects from India. The mission of this NGO and Studio is to make sustainable social projects through design, training, educating, collaborating and building communities with local people, students with support with experts, institutions, companies and professional from other disciplines i.e (Collective Approach) for better sustainable future.
