How to reuse a demolished building

Is it possible to construct a new building, just by reusing materials from homes and offices that have been knocked down?

That’s the dream of a pioneering Swiss architect Barbara Buser, who trains specialist treasure hunters to track down everything from window frames to steel beams for her buildings.

People Fixing the World finds out about her latest project, which is made of 70% reused material. We ask whether Barbara’s approach, which has a much lower carbon footprint than building with new material, can take off around the world.
