The upper volume seems to float above an almost transparent plinth. Cantilevers accentuate the dissociation of the various folds, each fold producing a face which captures the low-angled light produced by the orientation of the building. The lightly perforated opaque skin is divided into a number of triangles – some are matte while others are shiny –, thereby breaking down the structure of the basic volumes.

The building often has a different appearance at different times of day. The day nursery is located upstairs, while the other initiatives are at ground level. A bright yellow courtyard continues the line of the areas used by the nursery, the purpose being to shield them from the substantial nuisance caused by the goods trains and high-speed passenger trains which pass at speed here. The transparent features of the ground floor are arranged in such a way that the relationship with the railway line is constant, and perceived as a dynamic event.
