The vertical structure of the building is from the 1960s and was taken in consideration of the Task. The rhythm of the reliefs of pilasters, parapets and window levels remain largely intact and are strengthened by steel supports and trellises. Staggered planters over two window axis produce a new pattern in conjunction with the existing vertical structure. Depending on your location and viewing angle, the visibility of the original pilaster façade changes. From vis à vis you will see more of the rhythm of the 60's façade but by changing the angle of view, especially from a distance, condenses the added garden structure to a dense green wall, obscuring the underlying plaster façade.
The calculation provided by the civil engineer indicated that it was not possible to add any load to the existing structure of the façade. However, it was possible to build the new carrying structure on it's own foundation directly in front of the building. On the hollow rectangular supporting columns, planters were directly attached, which helped to stiffen and strengthen the supporting structure, as well as provide a large container for plants and provide shade from above.
