Made of reusable American tulipwood, ‘MultiPly’ is an interactive maze-like installation that prompts visitors to rethink how home and cities are designed and built. Highlighting two of the world’s biggest global challenges, housing and climate change, it presents modular design and material choice as a solution to these problems. From September 15 to 23 at Victoria & Albert Museum, London, UK.www.londondesignfestival.com
