The DakAkker

A short description of the NBS project

On top of the Schieblock office building in the centre of Rotterdam the largest rooftop-farm in Europe is situated, the DakAkker (literally: “Rooftop cropland”). Here fruits, vegetables and herbs grown and honey bees are kept. The DakAkker functions as a test site to experiment with different ways of green-roofs and farming in the city (vegetables and honey are sold to restaurants in the neighbourhood); in particular (with Pompenburg Park and Hofplein green roof) it is one of the projects of the City Initiative The Luchtsingel and exhibition-site during the International Architecture Biennale 2012. Luchtsingel is a foundation that aims at making a better connection between the northern part of Rotterdam and the city centre. The project was created in April 2012 by Binder Groenprojecten and initiated by ZUS (Zones Urbaines Sensibles) and developed by ZUS in collaboration with the Rotterdams Milieucentrum (Environmental Centre Rotterdam). The DakAkker is a ‘smart’ roof able to store 60.000 litres of water in times of heavy rain fall. It has also a social function for local residents who can be volunteers in cooperation with the local environmental organization, Rotterdams Milieucentrum. Furthermore, the Dakakker offers employment in their restaurant (Op Het Dak) which is located in the same building. Workshops, activities, events, courses and guided tours are organized. Organizations can also rent the location for their own events. Lastly, children from primary schools in Rotterdam can visit the roof to learn about healthy food and green roofs.
