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 point of the building, irrespective of material or function of the highest element (i.e., including antennae, flagpoles, signage and other functional-technical equipment).

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).

Official Name
The current legal building name.
Name of Complex
A complex is a group of buildings which are designed and built as pieces of a greater development.
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.
Status
Country
The CTBUH follows the United Nations's definition of Country, and thus uses the lists and codes established by that organization.
City
The CTBUH follows the United Nations's definition of City, and thus uses the lists and codes established by that organization.
Address
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.
Height
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 Hotel Rooms
Number of Hotel Rooms refers to the total number of hotel rooms contained within a particular building.

About J.W. Marriott and The Upper House
Constructed at the base of a hill sloping upward from Victoria Harbour, the Pacific Place Complex sits adjacent to Hong Kong Park, both of which were constructed on the site of the Victoria Barracks operated by the British Military. While the western portion of the barracks became public a green space interspersed with a collection of preserved low-rise structures from Hong Kong’s colonial era, the eastern portion gave way to the Pacific Place development. After the land was transferred from the Government of Hong Kong in the mid 1980’s, construction began quickly with Phase 1 opening in 1988.
Phase 1 included One Pacific Place as the as the J.W. Marriott and The Upper House which was originally constructed as a mixed use residential and hotel tower with 140 serviced apartments above 607 hotel rooms. As part of a later interior retrofit, the uppermost floors were converted from residential into the suites of the 117 key Upper House Hotel which opened in 2009. Combined with the JW Marriott hotel below, there are presently 719 rooms as well as a handful of restaurants spread throughout the tower.
The tower is perched on a hillside podium comprised of the three story Pacific Place shopping mall and a landscaped rooftop serving a courtyard between the towers of the complex as well as the publicly accessible street linking the main entrances of each building. The J.W. Marriott and The Upper House features a glass façade composed of triangular window bays maximizing views of the surrounding harbour, hilltops and skyline which has grown up around it since completion.
