Dubai Tall Emblem
developments have made a gate where reciprocity between many diverse
international cultures flourishes. The tall emblem of the za’abeel park can be
the expression of today’s vision of Dubai. As an urban viewpoint, the project’s
site on the park seems to be a focal point between the new urban expansion of
Dubai,Jumeira and Sheikh Zayed Road, and the older districts like BurDubai and
Deira. These two qualities initiated the conceptual view in our minds to call
the project the “Dubai Gate”.
the fact that the built form should refer to the history and identity of
the region and that the Islamic art and culture in the Arab countries has to be
observed, another two characteristics which are originated from the Islamic
architecture are also based for the design concept.
and Vault; that have been considered as a major fact in
the traditional Islamic architecture.
Geometry; that is the foundation for the Islamic
architecture in the form of fractal geometry or a kind of unity in plurality.
So the general
structure of the design is formed on the base of an Arch, a self supporting
shape. Through this idea, achieving two design aims becomes possible as below:
a townscape void through constructing a gate.
an urban platform of an urban scale underneath the arch.
Geometry and Morphology
factors influencing the project’s geometry and plan morphology are derived
majorly from not only the site’s geometry, its existing roads and focal
points, but also the regional climate and wind-force.
In response to
the former and for being very close to the Za’abeel Park’s entrance in
21-street, a strong axis is defined from this point to an area with the least
probability of any changes on the existing park roads. However, with regards to
the latter the north-west wind plays an important role in creating another
major axis along this direction. Needless to say that the west and east side of
the built form should have fewer surfaces blocking the sunlight. Thus a diamond
shape is being formed on the ground floor plan that later generates the
shape for the whole project.
In addition, an ellipse
is needed at the higher levels to cover three design factors:
elliptical plan for the view decking at top of the tower provides 360 degree panoramic
view to the city.
aerodynamic shape along the north-west direction reduces the wind force at top.
narrow corners of this shape in east and west side, that have sharper sunlight,
reduce the absorbed heat.
Simple Volume of the Gate
architectural form concept is an integrated movement starting from the horizon,
rising up and then sloping down to the ground ; being covered by an external
shell and then creating an arch, in the form of a simple gate. This simple form
is exactly what is necessary
for a monumental building to be stuck in people’s mind. The whole volume is also
composed of two major shells, the internal and external that their morphologies
are vice versa. They are being created from plan geometry that morphs from a diamond
on the ground floor into the ellipse at top. The ground floor major body is
built on the sides of that diamond, like two inscribed arms. In the external
shell, the intersected sides of the diamond morph into the ellipse and create a
smooth and aerodynamic volume with different perspectives; however the movement
in the internal shell is morphing the ground floor curves into a small diamond
at top to form the arch.
By the appearance
of the building general form, the space under the arch functions as an urban
plaza. Its shape is derived from the expanding geometry concept. Then, one of
the Plaza’s arms, which is toward the main entrance, is stretched out and
creates a passage to the building.
As it was said
above, the building’s structure is affected by the arch’s self supporting form
that transfers the loads to ground through both arms. Here, both internal and
external shells are performing as structure surfaces. They are two wings which
are connected together at the ellipse after shaping the vault. The structural
system is an integrated meshed network aligned with the diamond pattern on
façade and is made of the pipe shape profiles.
on the complex
The main concept
of the façade’s pattern is adapted from the Islamic fractal geometry that
brings fluency and unity in the whole complex. The pattern units are diamond
shape, the geometry which initiated the form. The characteristics of the
pattern on external shell are as below:
the volume transparency from down to up maximizes the top view to the city and
the climatic control at down. Moreover, this combination provides the differences
between the lighting qualities in day and night.
on the eye level perspectives by the pitted modules that become gradually
leveled at top to create a 3D elevation.
modules play different roles in sustainability and climatic
air trap modules located at the higher levels pull the wind
inside the tower’s arms, conduct toward the ground floor and then blow it out
on the plaza’s fountains. This process is like a cooling system blowing fresh
air on the platform’s open space.
solar cell modules are installed at the dome to provide the power
for the complex.
It is clear that
each diamond shape module is divided into smaller panels to not only create an
elaborate Arabic taste on the façade, but also make the installation easier.
The internal shell’s pattern is also an elaborated
diamond shape with a gradient from transparent to solid, in contrast with the
In overall, the
diamond shape pattern seems to be like divergent modules initialized from the
building’s head and then spreading down on the volume and then on the landscape
and finally become larger and fade near the site boundaries.
circulation is divided into two sections; one explains the circulations on the
ground and another is inside the building.
a) On the landscape, visitor’s movement to the
building is through two major passages. One of them is on the ground level,
moving directly from the park’s entrance to the platform where the elevators
are located to lift people up. In addition a ramp is connected to the platform
that turns around the back court yard, moving from the platform to the
underground. Another one is like a steep yard that leads from the entrance to
the podium where the functional sections are designed. Needless to say that
there is a parking ramp behind the building that opens to the 6thstreet.There
are also two other passages on the designed landscape that connects the
building to the existing sidewalks.
second circulation is the interior one.
In line with the project’s concept, the arch’s two arms provide the vertical
circulation within themselves.
There are two
lifts in each wing with a panoramic view to the city from one side, and a
sophisticated view to the interior space in south-east wing from another side. Lifts
also have a three dimensional movement align with the arch’s wings which
creates a different experience from moving through out a structural space. One
of the lifts group stops at the underground level and opens in front of the
conference halls; and there is also an emergency staircase set at the
north-west wing. At top there is a view decking in two stories that the latter
has a coffee shop.
The project has
a podium at the underground level which consists of a children’s library, two
conference halls for 100 persons and other necessary spaces. A parking area for
30 cars is also located beside the podium with direct access to the conference
lounge; however there is a vent space between them.

The general circulation is designed in a way that separates
the view decking visitors from users who come for the library and conference
halls through two different entrance passages.
