The current legal building name.
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.
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."
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.
Number of Hotel Rooms refers to the total number of hotel rooms contained within a particular building.
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.

Thamrin Nine is a high-rise complex situated near one of Jakarta’s most historic and socially active venues, the Bundaran Hi Monument, and will be highly visible along the well-traveled Jalan Thamrin thoroughfare. The development is most identifiable through the juxtaposition of two paired geometric towers, the most visible of which is Tower 1, the flagship of the development. A dense retail podium links Tower 1 and Tower 2, and taken together, the buildings form an identifiable, architectural composition defined by strong cubic forms and projecting rectangular volumes.
Inspired by the nearby UOB Plaza tower, Thamrin Nine Tower 1 is meant to rise with a visual presence that stems from its height, proportion, and simple extruded surfaces. This expression is bolstered by a layered façade with “floating” silver blue glass cladding, its planar language giving depth and dynamism to the tower while unifying programmatic variation. Subtle articulation of the façade through the use of specular silver edges and horizontal fins brings a sense of scale to the tower, while also providing passive shading to the entire building. The key element of Tower 1, set against its strictly planar expression, is a prominent, cantilevered, public observation deck that hovers above an outdoor skywalk.
The building integrates a range of public and private functions within 186,000 square meters of space. At its base are restaurants, retail shops, and a two-story atrium serving the tower’s office floors, which include a penthouse zone of offices with triple-height voids connecting multi-level tenant spaces. A separate lobby serves hotel floors at the top of the tower, where a central atrium brings light and air into the interior. At the top of the tower is an open-air roof garden arranged at varying levels to distinguish the public roof deck from private hotel amenities.
