Torre YPF

CTBUH collects data on two major types of tall structures: 'Buildings' and 'Telecommunications / Observation Towers.' A 'Building' is a structure where at least 50% of the height is occupied by usable floor area. A 'Telecommunications / Observation Tower' is a structure where less than 50% of the structure's height is occupied by usable floor area. Only 'Buildings' are eligible for the CTBUH 'Tallest Buildings' lists.

Postal Code

A single-function tall building is defined as one where 85% or more of its usable floor area is dedicated to a single usage. Thus a building with 90% office floor area would be said to be an "office" building, irrespective of other minor functions it may also contain.

A mixed-use tall building contains two or more functions (or uses), where each of the functions occupy a significant proportion of the tower's total space. Support areas such as car parks and mechanical plant space do not constitute mixed-use functions. Functions are denoted on CTBUH "Tallest Building" lists in descending order, e.g., "hotel/office" indicates hotel function above office function.

Structural Material

Both the main vertical/lateral structural elements and the floor spanning systems are constructed from steel. Note that a building of steel construction with a floor system of concrete planks or concrete slab on top of steel beams is still considered a “steel” structure as the concrete elements are not acting as the primary structure.

Reinforced Concrete
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from concrete which has been cast in place and utilizes steel reinforcement bars.

Precast Concrete
Both the main vertical/lateral structural elements and the floor spanning system are constructed from steel reinforced concrete which has been precast as individual components and assembled together on-site.

Utilizes distinct systems (e.g. steel, concrete, timber), one on top of the other. For example, a steel/concrete indicates a steel structural system located on top of a concrete structural system, with the opposite true of concrete/steel.

A combination of materials (e.g. steel, concrete, timber) are used together in the main structural elements. Examples include buildings which utilize: steel columns with a floor system of reinforced concrete beams; a steel frame system with a concrete core; concrete-encased steel columns; concrete-filled steel tubes; etc. Where known, the CTBUH database breaks out the materials used in a composite building’s core, columns, and floor spanning separately.


Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the architectural top of the building, including spires, but not including antennae, signage, flag poles or other functional-technical equipment. This measurement is the most widely utilized and is employed to define the Council on Tall Buildings and Urban Habitat (CTBUH) rankings of the "World's Tallest Buildings."

Floors Above Ground

The number of floors above ground should include the ground floor level and be the number of main floors above ground, including any significant mezzanine floors and major mechanical plant floors. Mechanical mezzanines should not be included if they have a significantly smaller floor area than the major floors below. Similarly, mechanical penthouses or plant rooms protruding above the general roof area should not be counted. Note: CTBUH floor counts may differ from published accounts, as it is common in some regions of the world for certain floor levels not to be included (e.g., the level 4, 14, 24, etc. in Hong Kong).

Floors Below Ground

The number of floors below ground should include all major floors located below the ground floor level.

# of Elevators

Number of Elevators refers to the total number of elevator cars (not shafts) contained within a particular building (including public, private and freight elevators).

Tower GFA

Tower GFA refers to the total gross floor area within the tower footprint, not including adjoining podiums, connected buildings or other towers within the development.

About Torre Repsol YPF

With its prismatic form, clean lines and dramatic winter garden, the new headquarters for Repsol-YPF—one of the world’s top energy companies—is a dignified corporate symbol and a modern landmark for Buenos Aires. The tower is also the tallest office building in Argentina.

The Torre YPF stands apart from the busy streets and avenues of Buenos Aires, its full height visible from all sides. Located on the edge of the stylish neighborhood of Puerto Madero and visible from the historic Plaza de Mayo, the tower is the easternmost structure before the open space of Costanera Sur (the Buenos Aires ecological reserve) and the broad waters of the Rio de la Plata.

The tower’s form is composed of two volumes generated from the interlocking shapes of a triangle and a square, rotated 45-degrees from one another and extruded skyward. The result is two distinct towers pressed together in a single, unified composition. The floor plates of each tower press outward in a gentle curve, causing the glass-and-steel skin to appear stretched across the building’s surface and heightening its delicate sense of thinness.

While the two interlocking towers share an aesthetic spirit, they are subtly differentiated. The triangular tower, reminiscent of a ship’s prow, tilts toward the river, while the square tower leans toward the city. The triangular tower is nearly all glass and has a lightly reflective finish and fine pattern of horizontal lines that accentuates its sense of volume. The square tower, on the other hand, has a more urban expression, with a grid of stainless steel panels surrounding square panels of glass.

The tower’s most distinctive feature is its six-story winter garden, located in the corner of the square tower near, but not quite at, the top. The winter garden has an emblematic presence on the façade, like a logo or a sign. Several large trees occupy the space, and at night, lit from within and visible from afar, the winter garden is a symbol for clean energy and Buenos Aires’ natural setting.
