Shigeru Ban completes Cardboard Cathedral in Christchurch | sustainable architecture |

The Cardboard Cathedral by Japanese architect Shigeru Ban opened in Christchurch, New Zealand.

The building was designed as a temporary replacement for the city's former Anglican cathedral, which was destroyed by the earthquake that struck the city in February 2011. With an expected lifespan of around 50 years, it will serve the community until a more permanent cathedral can be constructed.

The building features a triangular profile constructed from 98 equally sized cardboard tubes. These surround a coloured glass window made from tessellating triangles, decorated with images from the original cathedral's rose window.
