Name of Complex

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.

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

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.

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.

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."

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).

# of Apartments

Number of Apartments refers to the total number of residential units (including both rental units and condominiums) contained within a particular building.

# of Parking Spaces

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

Tower GFA

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.

CTBUH / Nakheel Asia Tour Report

19 April 2007 - Building Tour

About The Harbourside

The Harbourside was constructed as one phase of the Union Square complex, a large transit-oriented development placed atop Kowloon Station which serves a rail line linking Hong Kong Island to the airport. Union Square was designed as multiple towers interlinked through a large podium structure containing parking, shopping and transportation facilities all covered with an internal roadway network and a series of green spaces spread across the podium roof. The towers of the complex then rise from the perimeter of the site and feature unique façade designs for the portions of the podium within each tower footprint that creates a street edge.

The Harbourside was built at the south end of the complex, facing towards Victoria Harbour with a bowed shape as it rises from the podium levels. The structure had four large voids incorporated into the design in order to reduce the wind loading on the structure, while providing visual reinforcement of where the building is internally split into three individual residential towers.

The entire complex was built on air rights above the railway station on land reclaimed from Victoria Harbour. With water and public green spaces surrounding Union Square on two sides, The Harbourside as well as the neighboring towers have since become very prominent fixtures on the Hong Kong skyline.
