The precast concrete sandwich exterior walls of this apartment building are interesting. The white concrete facades have been created using three different types of concrete; Graphic Concrete, polished and sandblasted concrete. The different surface structures reflect light in a different way, making the facade puzzle-like and the traditional panel joints disappear.
With Graphic Concrete Smooth a velvety smooth, matt and even concrete surface is created that highlights the inherent beauty of concrete.
Due to differences in surface porosity, the different parts of the facade will change their character over time. The French balcony hangers on the street side contribute to liven up the street scene.
