Modernism has a famous
motto: A house is a machine for living in. However, as we progress further away
from the machine age, we are left with a question: what message should
architecture convey? What is the house of today?
Like other fast developing
suburbs in North America, Mississauga is seeking a new identity. This is an
opportunity to respond to the needs of an expanding city, to create a
residential landmark that strives for more than simple efficiency and that
provides residents an emotional connection to their hometown.
In place of the simple,
functional logic of modernism, our design expresses the complex and multiple
needs of contemporary society. This building is more than just a functional
machine: it responds to the significance of being located at the junction of
two main streets, elegantly bearing its landmark status and acting as a gateway
to the city beyond. It is something beautiful, sculptural and human.
Despite its landmark status,
the emphasis is not solely on height. Our design features a continuous balcony
that surrounds the whole building, eliminating the vertical barriers traditionally
used in high rise architecture. The entire building rotates by different
degrees at different levels, corresponding with the surrounding scenery. Our
aim is to provide 360 degree views for each residential unit, and to get city
dwellers in touch with the natural elements and reawaken their appreciation of
nature.
The Absolute Towers are
nicknamed as “Marilyn Monroe Towers” by the locals for the sinuous shape.
Tower A: 45,000sqm,
56stories/ height 170m
|
Tower B: 40,000sqm,
50stories/ height 150m
|
The larger of the two towers twists 209
degrees from the base to the top, making it very similar to Turning
Torso in Malmö, Sweden. The structural design was done by Sigmund Soudack & Associates Inc, a
Toronto-based structural engineering firm. The tower has six levels of
underground parking.
The following table lists the amount of rotation
for each floor of Tower 1.

First I started building a line in the conceptual mass model. This is the reference line for each floor where the central point of the ellipse shape. Because there are 56 levels of the building, I separated the line into 55 parts, which have 56 points indicated where the floor slab will be at.
The next step is to create the basic adaptive ellipse shape for the floor slabs. In this case, I started building the model in the adaptive conceptual mass model. On this stage, the turning angle of the basic ellipse shape should be relevant to the height of the level. Thus, I created a parametric instance value for this model, which was named "H".
In the picture above you can see that there are three more relevant values. "a" and "b" stand for the shorter axial length and the longer axial length of the ellipse. And these two values were constrained. The third value of the model is the rotation angle. This is the key of the formation of the building shape. In order to make the shape being able to turn "automatically", a formula was put in the parameter value blank. After studying the regularity of the rotation, (2 * atan((H - 285') / 200') + 180°) * t was filled in the spot. This formula looks like the picture showed below.
As you noticed, there is a "t" being multiplied at the end of the formula. The "t" is actually a type parameter in order to allow the user to change the shape of the building more easily.
Another vital hint here is the angle annotation and the length annotation should all be constrained to the central point. Also, these reference annotations and reference lines should be created before the shape being created.
After finishing the adaptive model, it comes to the third step. I duplicated the ellipse 55 times to put them on each reference points on the line after loading the adaptive model into the general conceptual model. Then I change the value "H" of each level. While this was happening, the ellipse would turn to a certain angle according to the value of "H".
The last step is creating the building facade. I loaded this conceptual mass model into a project and set different level of elevations referring to the level of the ellipse shapes.
Then on each level, I created a place-in-model blending component. This component is the curtain wall of each level. Finally, I set the materials for the floor slabs and the curtain walls.
Here are some renderings.
