Name of Complex

A complex is a group of buildings which are designed and built as pieces of a greater development.


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).

# 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).

About Nextower

Positioned outside the limits of the cluster of high-rises in the neighboring banking district, the PalaisQuartier forms the architectural highpoint of a new district in downtown Frankfurt—with shapes that catch the eye even from a great distance, its expressive shape creates an exciting counterpart. Together with the Thurn und Taxis Palais Townhouse (recently rebuilt to preserve its original façade), and the “MyZeil” shopping mall, the PalaisQuartier rounds out a new district which has a decidedly urban flair.

The urban planning concept from the outset envisaged the construction of an urban quarter on the former Post Office site that linked various facilities such as accommodation, hotels, offices, restaurants, event rooms and retail outlets with each other. The new combination of reconstructed space, inner-city shopping mall, office high-rise tower and hotel creates a lively urban place in the center of Frankfurt. The Thurn und Taxis Plaza forms the publicly accessible center of the new quarter, enriching the inner city.

Two materials, namely aluminum and glass, define the appearance of the face of the building, which is designed as segmented curtain façades. The eye-catching characteristic of the tower is, when seen from the side, the diamond-shaped fully glazed surfaces. They are integrated into the façade like crystalline bodies. In order to emphasize the crystalline character of the glass, diamonds are implemented as dual façades using highly transparent, untreated panes of glass as the outer layer, with solar protection integrated into the intervening space in the façade, and insulation-grade glass windows constituting the inner, thermal skin. If desired, the windows in the office high-rise can be opened to provide natural ventilation. The transparency of the high-rise façades with their non-reflecting windows makes it possible to look in and out, enlivening the high-rise and opening it up visually to its surroundings.

The tower’s slightly tilted façades are structured by the three striking fold lines and their height, which is defined by the design and derived from the overall shape. Inspired by Constantin Brancusi’s gleaming column-like artworks, the sculptural qualities of the office tower with its neighboring hotel tower serve as unmistakable points of orientation in the city’s fabric.

The tapering/expansion that results from the tilting creates office footprints with different depths in line with the building’s underlying geometry. The usable depth of the office areas, which are 3.05 m (10ft) high from floor-to-ceiling, is about 5.9m (19ft) in the tapered sections and up to 9.6m (31.5ft) in the zones that jut out furthest. This variance encourages a great range of different office layouts, from executive offices via combined offices with a central area for communicative shared usage, through to open plan offices.

The energy concept envisages that about 50% of the heating/cooling energy requirement is covered by sustainable systems. About 20% of the figure is obtained geothermally through a combined heat-pump and cooling system. The highly efficient central heat recovery plant relies on radiant heat from the shopping mall and the underground car park. It provides about 30% of the total heating energy requirement. The rented areas are cooled/heated by means of a heating control system for the respective building section integrated into the concrete ceilings. For this reason, there is no need for suspended ceilings in the sections containing office workstations. Ambient temperature, lighting and solar protection blinds are all centrally controlled by sensors, whereby they can be individually set at any time.

Nextower Chosen as Featured Building

The striking interrelationship of the tilted façades forms the central theme of the design of this office tower and its smaller neighboring hotel.
