X3 _ Perforated Info Tower


The Info Tower helps new arriving tourists and locals to find an indication to the ferry and its departure time, to get the weather of tomorrow, the local time and date, events in Piraeus and Athens… and in the same time offering some advertisement space might cover a part of the investment in the tower.

It’s the new emblem of contemporary, metropolitan Piraeus/ Athens, right at the entrance to the city and stands in a strong contrast to its omni-present classical greek architecture.

The info panels can also function as sun – and noise block. By placing them shifted over the edge of a slab, it can create some shadow and by inclining the lower panels,they can block street noise.

Design Strategy:

First extrude the panels, depending on their placement on the facade; then create ‘cuts’ because of an exceptional interior space, which needs more direct light and views; then increase some panels, which occupy a marketing strategical place on the facade. Like edges, the center at the top and the bottom…

Analyse of strategical placement on the Piraeus Tower

Grasshopper Algorhythm:

1. Panel extrusion increases throughout the height

2. Definition of 3 heights of certain importance

3. Panel extrusion increases to those heights

4. Definition of some important points for views…

5. Lower the panels within a certain distance to such a point

–> depending on the distance to this point

6. Definition of a strategic placement of the info panels

–> Increases the height of the closest panels

Rhino and Grasshopper Model

I mostly compared the z-coordinate of a point to a certain height

and then analysed the distance to the height

if the z-coordinate is lower than the height, then it should do a certain panel… and so on…

I did the openings in the same way, by analysing the distance to such a point

Last Sketch:

After this analyse of the perforation of the info panels, I think to focuss more on the placement and the importance of the info panels is more important and should define the overall image of the tower.

The perforation of those panels, because of a need of more light and direct views should be secondary.

As indicated in the lower sketch: At important areas on the tower, the panels should be larger and the distance to the neighboring panels should be larger as well, so the important panel stands out of the homogenous panel mix.

Also the lower panels should be inclined and smaller, because of legibility factors and to block noise, as mentioned above.


(this post has to be consideres as my post-test.)

This table is not finished yet, there are still some problems to overcome,

e.g. the realations, what of these parts is fixe, and which could be moved, as a question of reference system.

The planes and cubes are created by ‘extruded’ lines, and the legs are positioned with ‘offset’.
