Height

To Tip:
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest point of the building, irrespective of material or function of the highest element (i.e., including antennae, flagpoles, signage and other functional-technical equipment).

Architectural:
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).

Type
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.

Address
Function
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
Steel
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.
Mixed-Structure
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.
Composite
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.

About 111 West 57th Street
In a bold move blending thoughtful design with urban sensitivity, 111 West 57th Street typifies the luxurious extreme of the superslim typology in New York City. Containing only 60 units, the tower will offer an exclusive, centered perspective on Manhattan’s Midtown neighborhood, affording uninhibited views of the entire urban region.
The tower’s form is derived through an unconventional interpretation of what is possible when working with the requirements of the Midtown zoning envelope, multiplying the height of each setback to present a feathered, rather than a stepped, profile. New ways were also explored to exploit the possibilities of terra-cotta, one of the most flexible and beautiful materials from the golden age of the Manhattan skyscraper. Blocks will be extruded and glazed, then stacked into undulating “pilasters” on the east and west façades, their staggered waves combining into a subtle and distinctive moiré pattern. Each pilaster ascends to one of the stepped setbacks above, so the tower appears to dematerialize as it rises. Alternating between them are vertical bands of glazing trimmed with bronze. To the north and south, views of the city and nearby Central Park are maximized through the use of taught, cleanly detailed glass walls. The footprint of the building was kept as compact as possible, positioning it well back from the street to respect and preserve the landmark Steinway Building at its base.
The result is one-of-a-kind superslim: an exercise in sensitive urbanism, the creative use of technology, and a pride of place that could only be found in Manhattan. Topping out at over 435 meters, when completed it will be among the tallest towers in the city, and one of the most slender skyscrapers in the world.
