Native title of the NBS intervention
Quartiersentwicklung Neugraben-Fischbek: Fischbeker Reethen
Short description of the intervention
The Senate of Hamburg commissioned IBA Hamburg GmbH with the development of the project which aims at realizing two new, family friendly residential districts in Neugraben-Fischbek, the Fischbecker Heidbrook and Fischbeker Reethen, which will offer 3000 residential units in total. (Reference 10) Out of the two districts, Fischbeker Reethen is planned to be the "Garden City of the 21st century", which is why this NBS case focuses on that project. The Fischbeker Reethen project pays attention to sustainability, having a blue-green infrastructure (large green surfaces, waterways and a lake that serves as a basis for the rainwater management of the area). A further aim of the project is to create a new district for the growing city, that with its good infrastructure, public transport connection and educational offers will help the integration of refugees into German society. (Reference 12) The construction of the buildings followed by the green and recreational elements is will start in the second half of 2020, and the handover is planned for 2022 the earliest.
