  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).

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

Taikoo Place

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.

Office

Structural Material
All-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 an “all-steel” structure as the concrete elements are not acting as the primary structure.

All-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 and/or steel reinforced concrete which has been precast as individual components and assembled together on-site.

All-Timber
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from timber. An all-timber structure may include the use of localized non-timber connections between timber elements. Note that a building of timber construction with a floor system of concrete planks or concrete slab on top of timber beams is still considered an “all-timber” structure as the concrete elements are not acting as the primary structure.

Mixed-Structure
Utilizes distinct systems (e.g. all-steel, all-concrete, all-timber), one on top of the other. For example, a Steel Over Concrete indicates an all-steel structural system located on top of an all-concrete structural system, with the opposite true of Concrete Over 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 within a composite building’s primary structural elements.

About One Island East

One Island East comprises 59 office floors with a typical floor plate of 2,300 square meters (24,760 square feet). One Island East is the landmark of Taikoo Place, recognized as one of the Hong Kong’s best planned business hubs, managed by Swire Properties. The portfolio offers some 6 million sq ft of prime commercial space for local and multinational corporations.

The basic form of the building is a square plan with rounded corners and a central core. The two corners facing north and south open up at the top floors to address the Harbor view. At the base, the two corners facing east and west open up to address the open space. The edges of the four façades sail beyond, creating a floating effect and giving lightness to the building. Architectural fins are introduced on the façade in a staggered pattern to add texture and scale.

Without a podium structure, the tower sits freely in front of a large landscaped open space to the east. The canopy at the porte cohere is specially designed as a piece of sculpture. The landscaped area beyond is designed to have platforms at different levels incorporating water features. This urban landscape gives an appropriate scale as a forecourt to the building and provides a leisure space for both the enjoyment of office workers and for the neighborhood.

The upper main lobby is connected to the rest of the office complex at TaiKoo Place via a bridge at the northwest corner. Through a well-established system of link bridges at the existing podium level, pedestrians can gain convenient access to the MTR Quarry Bay Station. The One Island East building not only energizes the whole of TaiKoo Place, it also plays a leading role in transforming the neighborhood into a better environment.
