faceted icon – final post

The observation of the negative aspects of the existing towerhas been taken as the starting point of the project :bad propostions were making the building look too massive. In order to react on this aspect, the decision was taken to fragment this mass and go away from the rectangular perception of the tower in order to let the building breath with some public spaces.

The project was treated at two different scales :

one from far away in order to create an icon and a landmark,which will be more about shaping the building,

and the other from closer, to provide different perceptions and adapt to natural conditions.

The shaping of the building is contextualized with the surroundings : the fisrt step has been to take some pointsaround the building such as the acropolis, the station, the park, some piers, the end of the harbour.

Those points are then transformed into vectors by linking them with the closest corner of the tower. They are then scaled accordind to the same factor for each vector.

Those vectors are then distributed according to their length on the tower, and they are used to translation vectors from the corner in question to the new view point.

This principle is applied for the middle part of the building, corresponding to office program. The bottom part is already contextualized by the close relation is has with the surrounding, while the top part is starting to lose connection with the context because of its height.

If we take a look at one storey only, we can see that 2 points are defined by the minimum space the fire stairs will take and one by the view. The last point will be determined in order to keep a fixed ratio of 30% per floor of extra space.

When the view point correspond to the same corner as one of the fire stairs points, it creates instead a 5 side-polygone.

From far away, the main idea is the shaping and the framentation of the tower, while we can have a glimpse at some opaque and transparent zones.

The sections evoque the connection with the public space. Before, the public space ended at the edges of the building. With this project, the public space goes into the building as a connecting void. It reuses the existing passage as a monumental entrance, reaching a floor with a café, and continuing straight to the fire stairs for the rest of the tower.

The structure is composed mainly with 2 facets per floor, connected at the floor height to the existing pillars. Sometimes some higher facets are set when there is pulbic space behind.

The first layer is composed of glass following the faceting, each panel having a width of about 2.5 m according to truck transportation, while the external pattern is added, with some losanges taking the porportions of the big facets and scaled according to two parameters – one visual and one technical.

The parameters are used both as scaling factors for the losange pattern. The first one derives form the sun incidence on each of the facet. It is being calculated and then influencing the scaling. The gradient on each of the facets indicates the level of sun intensity on them : the white represents the less exposed faces while the black shows the most exposed facets.

The second is about creating a fluidity and continuity between the facets to have an impression of a whole. Therefore, the values of scaling inherited from the image in grasshopper are comprised between 0 and 1.
