Ukraine has seen many of its cities and towns destroyed. One day they will hopefully be rebuilt - with great costs and a large climate footprint as a result. But what are the alternatives? Danish NGO, Arkitekter Uden Grænser (Architects Without Borders), is already working on a solution: With the pilot project Build-back-green a sustainable building system using biogenic materials - straw, clay, and timber – is introduced in the Ukrainian city of Voznesensk.  Can rebuilding in war-torn or disaster struck parts of the world show a way forward to a more sustainable form of construction? And how do you balance that with the urgent need to recover quickly and cheaply? In this episode, host Michael Booth meets the chairperson of Arkitekter Uden Grænser, Christoffer Breitenbauch, to hear more about the organization's work and its new project in Ukraine. Let’s Talk Architecture is a podcast by Danish Architecture Center.
