In the heart of cities, lost in the depths of the woods or isolated on a paradise island, ecological habitat is constantly being reinvented all over the planet. When it comes to construction, many builders are combining creativity and innovation to face the environmental challenges of tomorrow. In northern Germany, the city of Hamburg and its district of Wilhelmsburg truly act as open-air laboratories. On a 30 hectare site, 17 buildings with varied and innovative ecological profiles have emerged… thus transforming architectural utopias into modern and realistic dwellings. But first let’s go to the east coast of Africa, to Tanzania on the island of Chole (to be pronounced cholé). Only accessible by boat, this little piece of land without road, electricity or even drinking water hides a totally disconnected and ecologically exemplary eco-lodge. Perfectly integrated into the surrounding nature, it was built from local materials while especting traditional construction techniques.
