Height

To Tip:
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).

Architectural:
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).

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.

Country

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.

Residential
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 Stadthaus
Apart from the concrete-built ground floor, Stadthaus is an entirely wooden structure. Stadthaus is one of the tallest timber residential structures in the world. It is the first high-density housing building to be built from pre-fabricated cross-laminated timber panels (using spruce planks glued together with a non-toxic adhesive), including all load-bearing walls and floor slabs as well as stair and lift cores. Each panel is prefabricated including cutouts for windows and doors and routed service channels. As the panels arrived on site they were immediately craned into position and fixed in place. Four carpenters assembled the nine-story structure in 27 days. The speed of the construction in such a densely populated environment is especially relevant, as was the lack of noise and waste, creating far less intrusion on the local community.
Concerns associated with timber buildings are predominantly related to acoustics and fire protection. Timber buildings are classified as poor in terms of their acoustic performance due to the light structure as compared to reinforced concrete and masonry. However, cross-laminated solid timber panels have a significantly higher density than timber frame buildings. They provide a solid structural core on which different, independent and separating layers can be added. In Stadthaus an economic layering strategy of stud walls, floating floor build-ups and suspended ceilings, gave sound attenuation far in excess of building regulations (58–60db).
In a fire, solid timber elements, such as cross-laminated timber panels, take longer to burn than dimensional lumber. For Stadthaus a series of tests were conducted allowing the design team to demonstrate a fire resistance of 90 minutes. This is based on the charring rates of the timber panel and two layers of plasterboard. The actual performance would be even better, since the calculations are conservative and do not take into account timber’s ability to “self protect” once a layer of char forms on its surface.
It was a requirement from the social housing client that a separate ground floor entrance was provided for the affordable units. This resulted in a mirrored floor plan from east to west, with an identical entrance to each aspect. Both tenures are served by an individual staircase and lift. The five upper stories are designated for private sale and the three lower for social housing.
