Sake van den Berg: IJburg II

Sake van den Berg was one of a select group of surveyors personally chosen by the Dutch government to assess the IJburg II project in Amsterdam.

Sake van den Berg is a partner at property consultancy BaseValue B.V and one of a select group of individuals chosen by the Dutch government to assess the IJburg II project. The huge residential project will see thousands of properties being built onto four artificial islands in the city’s lake. When fully complete, the archipelago will be home to around 45,000 people in 18,000 homes.

The IJburg project began in 1997 and so far has seen the completion of six of ten planned islands. Phase two of the project involves the gradual construction of the final four islands. The valuation of IJburg II took place between 2009 and 2012.

The area of water which the IJburg II project covered belonged to the government and the municipality of Amsterdam bought it to develop a new residential area, creating a city within a city. In 2009 to 2012 a party of specialised surveyors including Sake and three other RICS professionals undertook the massive task of assessing the area.

At that time there were no official Dutch valuation qualifications, therefore RICS professionals were selected to guarantee consistency in such a complex project. The team ultimately decided to use a residual method to evaluate the site, first making an estimate value for the final development and then deducting the cost of purchase, development and associated ecological costs.

Land making started in 2014, with the construction of the first houses in 2018. The development of the archipelago used a technique known as the “pancake method”. The technique involves a porous screen being placed in the water to create the desired shape of the island. Sand is then sprayed onto the screens to form a layer of sludge, this layer eventually settles and hardens; creating a layer that rises above water level and forms the new land.

The project, which has been considered an innovative solution to tackling Amsterdam’s housing shortage, will not only provide thousands of affordable new homes, but will also boost the local economy by creating an estimated 12,000 new jobs.
