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).
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."
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest occupied floor within the building.
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).
The number of floors below ground should include all major floors located below the ground floor level.
The current legal building name.
Other names the building has commonly been known as, including former names, common informal names, local names, etc.
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.
The CTBUH follows the United Nations's definition of Country, and thus uses the lists and codes established by that organization.
The CTBUH follows the United Nations's definition of City, and thus uses the lists and codes established by that organization.
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.
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.

Number of Parking Spaces refers to the total number of car parking spaces contained within a particular building.

Located in Moscow City, the dense, bustling financial district of the Russian capital, OKO - Residential Tower offers an elegant modern example of a residential high-rise. The structure is part of a twin tower development that includes a smaller office building, and its design is responsive to its smaller twin. The façades of the two towers are articulated with crisp diagonal folds and linked by a faceted base, generating an arresting shard effect that defines the buildings’ appearance. The canted folds allow the towers to taper away from one another as they rise, creating a dialogue between their bold, simple forms.
The towers form an L-shaped composition at the ground plane that is pulled to perimeter of the site. This placement works in tandem with the façade folds to allow the building to cant over the major roadway infrastructure that abuts the property line. A landscaped plaza sits at the base of the buildings and creates a sheltered, private garden that guides hotel guests and building residents to separate lobbies. This pedestrian-scaled space offers welcome respite from the bustle of Moscow City, where open space is a prized commodity.
The building’s all-glass façade offers several amenities that benefit its occupants. Ventilated mullions can be opened manually to allow natural air flow into the interior. These mullions also help to mitigate stack effect. Along with their practical implications, such features create a dynamic, shifting exterior.
The elegance of OKO - Residential Tower is apparent in every detail—from the clarity of its bold yet subtle forms, to the rich materials of its gracious interior spaces. It serves as a precedent for design excellence and as a key destination within Moscow City.
