In 2012, a group of architects decided to transform a polluted and deserted shipyard in the North of Amsterdam into a creative co-working space called `De Ceuvel`. To restore the polluted soil of De Ceuvel, phytoremediation methods were implemented. The full area is cultivated with plants that absorb or stabilize soil pollution. Through community-driven development, the site opted for a sustainable building approach by investing in a solar-powered heating and airconditioning system and compost toilets. The system at De Ceuvel is fully circular, wastewater is purified through bio-filters, and nutrients are re-used for the production of food. Old houseboats were given a second life to provide 17 sustainable ateliers for entrepreneurs and artists. A wooden deck connects the ateliers to protect the restorative ecosystem, and limit the contact of visitors with the polluted soil. After 10 years of use, the site will be returned to the Amsterdam municipality, cleaner and richer than ever before.
