bouwen met StcicilThe glass curtain wall, insulating sound, next to the highway and the two extra levels on top attract the most attention. For this project the prefabricated light steel framing system (StarFrame) has been used in the Netherlands for a major rooftop extension for the first time. The prefabricated floor-, wall-, roof- and facade elements for the extra stories are manufactured in the factory and assembled at the building site.

The building achieved the status demonstration project Industrial, Flexible and Demountable Building, which meant it was awarded with a subsidy of 250,000 Euro from the total Building budget. The transformation of De Leeuw van Vlaanderen in Amsterdam is rather unique because of the combination of operations (rooftop extension, sound insulating facade, changed traffic system) at a remarkable spot just 3.5 meters behind the crash barrier of the A10.

The most striking renovation intervention is the rooftop extension of two stories. It acts as a landmark for the uniformly shaped neighbourhood. Furthermore elevators are added to make all apartments accessible. The balconies are now facing the quieter back side of the apartment as opposed to the earlier highway facing side. The old storage rooms on the ground floor are added to the apartments. This way the facade facing the street is changed from a closed and 'anonymous' basement to a living façade, which is important for successful urban revitalization.

res_amsterdam_left02The old seventy-two apartments where renovated in to fifty-four apartments on the third, fourth and fifth level and thirty-six maisonettes at street level and in the rooftop extension. These maisonettes meet the need for larger and more expensive houses in the neighbourhood. Anyway almost all the old tenants return to live in the new De Leeuw van Vlaanderen.

The transformation of De Leeuw is meant to be an example for the rehabilitation of the whole of Amsterdam-West.
