After 30 years running these 1,100 rental dwelling units, the public body which manages them decided to hold a public tender contest for the refurbishment of these nine blocks next to Amsterdam airport. long talks, the ambitious proposal which won the contest was deemed not viable due to technical reasons and to the resistance of the client and the residents themselves.

In the end the project has basically involved the renovation of all the building enclosures. Lastly, both a set of solar panels on the roofs and a new centralised heating system have been installed which have improved the energy balance of the complex.
