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.

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.

residential

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 The [email protected] Block 1E

The Pinnacle @ Duxton defines super-density housing with 1,848 apartment units built on a plot of only 2.5 hectares (6 acres)—only slightly larger than two football fields. Public housing as an architectural typology is inherently complex. It marries housing—the most private of programs—with public space. The public housing project addresses pragmatic, financial, social and even political issues. Add to that an irregular west facing site in the heart of Singapore’s congested central business district, trees to be conserved and required connections to the neighboring park and community center, and the brief is incredibly complex.

The Pinnacle @ Duxton resolves these issues in an elegant manner and in the process creates a totally new aesthetic for public housing and typology for tall buildings. It boldly demonstrates a sustainable urban high-rise, high-density living and initiates an innovative typology of public communal spaces that are metaphorically reclaimed from the air. Seven tower blocks are placed in the most open and porous way, creating urban windows that frame the city skyline. With this maneuver, the layout eliminates overlooking between units; optimizes views, connection, air and light flow; minimizes western exposure to reduce solar heat gain; and includes the conservation of historical trees. A large forecourt for the towers was created, maintaining visual connectivity with the existing Tanjong Pagar Community Club, which is a major community node for this neighborhood.

Within the development, residents enjoy the convenience of shops, a food court, an education center, a childcare center, and two residents’ committee centers. Beyond the development, residents are served by two train stations which link them to the island-wide mass rapid transit system and bus stops at the development’s doorstep with a bus interchange depot. Exploiting the inherent sustainability of the high-density, high-rise housing model, The Pinnacle @ Duxton creates a walkable and diverse community, and provides a connected, convenient and compact model of sustainable urbanism.

On the ground, a new architectural surface warps, peels and flows over the carpark and services, efficiently organizing vehicular and pedestrian circulation. The linear block layout allows for a direct services network in the car park; a double-volume carriageway running under the blocks accommodates the fire engines and waste disposal. The peripheral arrangement of service cores allows for the car park to be efficiently and clearly laid out. The new architectural surface is a lush environmental deck that connects strategically with the existing urban network while forming a green lung for the city. Landscape elements comprising pavilion, benches, and exercise nodes are plug-ins to this extended park network and function as location markers as well as vibrant community nodes.

Layers of tree screens border the site and pathways to provide varying degrees of opacity and privacy, softening the massiveness of the towers to create a human scale. Integrated within this landscape is an outdoor gallery, “Traces,” which captures the historical significance of this site by tracing the outlines of the original two public housing blocks which were built in the 60s.

Continuous Sky Gardens on the 26th and 50th floors weave through the seven tower blocks, forming a simple yet powerful sculptural skyline that creates a strong identity for the project. Twelve Sky Gardens are conceptualized as displaced landscapes like a Sky Gym, Hillock, Crater, Meadows, Lounge, and Beach. They function as an extension of the living environment for residents, forming almost 1 hectare (2.5 acres) of new land. Designed with children playgrounds, an outdoor fitness gym for the elderly, landscape furniture resembling beach deck chairs and outdoor sofa sets; they provide diverse, creative and unusual spaces for community interaction. They also function as areas of refuge in case of emergencies and allow the sustainable sharing of mechanical services, reducing seven sets to just three. The seamless connection created by the linking sky bridges allow for the entire development to be serviced by a single Building Maintenance Unit.

The individual apartment unit is designed with growth of the occupants in mind—from newly-weds to homes with kids, then teenagers and later grandchildren. The pre-cast flat slab system and structural column zoning allowed the flexibility of wall placement in lightweight concrete, which extends 400mm (15.7in) on either side of the grid—thus rooms can contract or expand to suit the occupants.

Efficiently constructed off-site, the pre-fabricated concrete building components were delivered and put together on-site. Residents were given an unprecedented choice of exterior façade treatments—planter boxes, bays, bay windows, windows, and balconies. The façade is atomized into modular panels strung together to form seven sets. Composed by simple rules, the layered sets form a complex façade. The pre-fabricated panels incorporate both structure and services—including columns, beams and service ducts. With a simple and affordable application of paint finish, a highly differentiated façade is created from an undifferentiated fabrication process—creating visual interest and reducing the perceived building mass.
