Tetris Tower – final review

This project has 2 key word:



The goal is to create a facade composed by the modular panels system which is an tessellation geometry like a tetris.

1. Geometry research

2. Geometry adapted to the tower

3. Data research (sun study)

4. Data research (wind study)

5. Data research (view study)

6. Making a gradient of these parameter to analyze in grasshopper and get an parametric variation on the facade.

7. Global analytic step to compose the facade

8. Taxonomy of the panels

9. Type of the windows for each parameter

10. Type of the glasses for the view type

11. Elevation

12. Detail

13. Perspective

Tesselated panels – pinup progress

The global flowchart

One side we have parametric elements which is a research of data and other side we have geometrical element which is panel’s design.

The project is based on 4 main data:





Data 1: Sunlight

An analyze on GHX to get the average sunlight exposition for year

Data 2: Wind

An analyze on GHX using the wind rose map to get the average wind solicitation for year

Data 3: View

Analyze the context and define the view zone on the tower’s facade

Data 4: Fire-scape

the position is determined by the most optimal face, north facade

Making a image gradient of these 4 data to use on image mapper.

Making a taxonomy in relation with these data

The detail of each panels with 4 type of opening

Feedback system: improve the gradient tolerance by the analyze of Athens’ facade composition (e.g : glass filling ratio)

Response -Breathing Tower-

From the mid-term critic, some points have to be developed more:

-What is an iconic building??

-scale up the facade taxonomy because the biggest is a human scale (~2m)

-reduce the geometry composition to optimize the prefabrication.

Maybe, one of the solution to get an iconic tower is to focus on the view. Sometimes, there is an exception in the system which confirms the rule.  The convex and concave can be attribute in this iconic moment.

Mid-term Review “Breathing Tower”

Concept & Study Model – Using the convex and concave surface, to create a closer interaction between inside and outside. This situation creates a new dynamism in this area and gets different types of view from inside or from outside.

To optimize and to keep the best relation between inside and outside is not easy. This is why the system is based on the parametric approach.

Starting the analyze with the existent element and creates an analytic grid with different degree (from 1 to 4) of lighting cross-referenced with the program.

Then, to decrease the orthogonal grid and to modulated the composition, apply the tessellation – Aperiodic Tilling – system.

Apply to the analytic grid.

Another particularity of the tessellation: Edge.

Modify and create a new tessellation with the hexagonal grid. This method unifies and decreases the orthogonality of the tessellated facade.

Making a taxonomy list of different type of frames from level 1 to 4.

Replace each frames of tessellated grid by the frames of taxonomy using the level of lighting tones (1-4).

For the lens, use the attractor parameter as a strategic point of view. If the angle becomes tight, the relation is different.

Taxonomy of the lens


Detail, sometimes we get a double weight of the frames because of the modulated unity(dash lines)


Esquisse II

Inspiration of the project comes from different factor…

Starting to hexagonal grid

Put some attractors to define different zone of programm

Then interact these parameter to different type of panels: flat, inside, outside.

2 variation of section: panels on the structure or panels between the structure

Tower Image

The materiality can have a close relation with the form of facade. In this case, we are an exploitation of geometry to create a kaleidoscope effect for modify the inside view.

CS Coral II

To get more element to interpret the case study in architecture, here is an extend study of Coral.

For understanding its organization and geometry, one type of coral is chosen: Star Coral.

We can see 2 main layers: Skeleton and Organism.

The organism becomes inside of the skeleton and then this organic parts move their tentacles to get some preys.

This kind of movement create different type of opening.

Then the skeleton is composed by a series of polygons.

We get some  quadrilaterals, pentagons, hexagons, heptagons, octagons.

If we calculate an average of these geometry, we get exactly a hexagon.

The base of the coral is made by a hexagon system.

Its particularity, which is the fusion and dissociation, create a complex organization of many kind of polygon from this hexagon system.

Another aspect of polygonal grid organization is each points have 3 lines.

Focus on the organic layer, we can see another type of structure.

The composition appears like a concentration to one point which is the pore.

Different type of panels can examinate:

-Concave lenses

-Convex lenses

-Fix panel



The elevation explain the type of different panels.

8 types generate from different condition and programmatic problem.

The first sketch of H&dM explains one of this aspect.

When you have a merchandise in inside, the lens is concave for optimize the show window’s view.

Then we can understand the position and the meaning of these yellow concave panels coming from facade zoning.

One more rule is the vertical number is limited.

Same approach in Grasshopper.

Place some points which making zones.

Then generate the one type of surface on the diamond grid structure.

x2 Prada Tokyo – H&dM

For this exercise,  the  focus point is the materiality of the facade  and their relation in the building’s thickness.



In the section and the plan of Prada Tokyo, we can observe that some diamond’s panels is curved. Sometimes it’s convex or concave and some panels are filled. We can see more clearly in next picture.

The reason that these panels are different is influenced by the view and the sunlight. The sketch on the below of H&dM give me more hints to understand the relation between material, context and function.

The lenses of the glass create like a magnifying effect which is in close relation of the view and perception. The conception of the lenses is based on the human scale.

The parametric model is a modification and evolution of the X1 and the simple diamond surface takes a volume.

I add some function fore the surface made in X1. Click Here to x1 exercise

and then panels’ position parameter should be studied too…

Esquisse and 1st approach

Pireaus Tower is an important icon of this area.

The facade proposal has to resolve this problematic but also an close interaction to the context beause of his site’s complexity.

We can divide this tower in 3 part:

-The bottom has a close relationship with the city (market, port, church, place, street or another public space)

-The middle part is introverted in itself because of the other building’s proximity

-The top has a 360 degree’s view and can have a relation with the entire Athens (particularly Acropolis)

We have an alternation beteween open and close element.

However, I’m called out also by the larger context.

It means that the analyze on the top explains about the tower and his surrounded environment.

Maybe from the larger analyze, we can have more hint for our project.

Analyze large scale 1

We have, in large scale, our Pireaus Tower on the border of the port and the sea.

Here is is a cumulative point of many urban element and it’s opened for everything of the context.

And this is where there are a lot of wind too.

Border of the sea and the frontal position of Pireaus Tower make a lot of wind in this area.

One of the important parameter is the wind.

The form of the Tower can be influenced by wind flow.

Using this wind we can maybe produce more electricity of this area from wind turbines.

The thickness of the facade can integrate this element too.

Analyse large scale 2

The composition for the urban system of Athens is interesting too.

We have an alternation between void and mass.

For example, we can check in Google Earth that each building have a court but we can’t see this when we walked in the street.

We observe that each building has its own front and back.

The reason can be influenced by the needs of the shadow and the view.

The picture on the below is the inside of the residence building where we have balconies and court.

This Void-Mass makes pores in this city.

As a reference, I took the picture of the rock of Athens’ sea and as same as this image, the porosity is also an important element.

In this pore, people can have their comfortable life.

For this 2 parameter, this is my 1st approach.

It’s very formal but maybe this can be one of the piste for my project.

The intervention for the facade can be integrated a new function in its thickness.

Parameter 1: Wind

Parameter 2: Porosity

The facade is a structural system and is also a rhythm  to organize the transparent part of this building.

One of the important element is the glass panels which have differents types.

Their concept model explains this pattern language of the glass material.

A pattern of different type of panels is defined by parameters depend of view, sunlight or another factor.

Sketch of H&dM for the conception of the facade

Plan & Section, whole facade (even the roof ) is composed by same elements

A first test GH with 2 types of diamond panels

A GH code is defined to have 4 types of window and it can be more complex if the parameter is not random.

Get 4 types of panels.

This is the flowchart.

For more deep analyze, the parameter, in place of random, can be generate by different factor as a view, sound, light, airflow and more possibility to develop this first approach.
