North Point Municipal Service BuildingAdaptive Type of Municipal Service BuildingLocation: North Point, Hong Kong SAR Academic work: municipal service building
The simplest tensegrity structure (a T3-prism). Each of three compression members (green) is symmetric with the other two, and symmetric from end to end. Each end is connected to three cables (red), which provide tension and precisely define the position of that end in the same way as the three cables in the Skylon define the bottom end of its tapered pillar.
Tensegrity, tensional integrity or floating compression is a structural principle based on a system of isolated components under compression inside a network of continuous tension, and arranged in such a way that the compressed members (usually bars or struts) do not touch each other while the prestressed tensioned members (usually cables or tendons) delineate the system spatially.[1]

Tensegrity structures are found in both nature as well as human-made objects: in the human body, the bones are held in compression while the connective tissues are held in tension, and the same principles have been applied to furniture and architectural design and beyond.

The term was coined by Buckminster Fuller in the 1960s as a portmanteau of "tensional integrity".[2]

Structure Prototype Experiment
In the M1 1st semester we have researched the integrity structure and its application. The Integrity Structure system is primarily composed of tension elements and support elements, and these two structural components can serve as building elements such as floor slabs, cables, and columns. This experiment explored different types of Integrity Structures and tested various aspects of Structural Quality, such as anti-compression, anti-bending, anti-torsion, and anti-shearing. The goal was to ultimately identify the Integrity Structure most suitable for architectural applications.

The Relationship Between Vacancy Rate & Booth Quantity

North Point Street Market’s Program in 1969

Since the 1960s, Hong Kong Municipal Service Buildings have met a significant problem. Their booth vacancy rate rose consistently in this period. Since that, Hong Kong Government has tried to launch a series of Municipal Service Buildings with different functions to fit various demands at different times. As a result, Municipal Service Buildings in Hong Kong, like a series of products, change their types all the time to meet society's needs.

The Schedule of North Point Street Market


North Point Market Building’s Typology Iteration (from 1970s to 2020s)

Orange Block: Block A (Food Market and Cooked Food Centre)
Red Block: Block B (Indoor Stadium)
Blue Block: Block C (Society Service and Library)
Green Block: Block D (Hospital and Health Care Centre)
This study constructs the function block model of the North Point Market Building to illustrate how the demand for different functions varies over time, based on the residents’ age group in this area.

To simplify the function block model, this study integrates different functions into four blocks, some of which are existing in the original prototype and some of which are newly added. By observing the size of the blocks, the study can obtain the information about the demand for certain functions in this Market Building in different years from the change of the blocks’ volume. This method enables the study to visualize the demands of the North Point Market Building through these diagrams.

This research relies on the evidence of the local residents’ age group, which is obtained from the Hong Kong government’s website. The function demands vary according to the different age group components. These function demands are then incorporated into the appropriate functional blocks. The purpose of this process is to establish a link between the residents’ age group and the building’s typology.

The large-scale model diagrams also illustrate the trend that can support the prediction of the typology change in the subsequent decades. Block A contains a street market and a cooked food centre. Block B features an indoor stadium. Block C offers social service facilities such as a library, an office, and a meeting room. Block D provides a health care centre for young children and senior citizens.

The diagrams show that the street market function for this Market Building grew steadily from 1976 to 1986, and stayed the same in recent decades. This suggests that the 1986 typology of this Market Building can meet the residents’ street market needs in later decades.

The situation of Block C- society service facilities is similar. It did not change much from 1996 to 2016, but it increased slightly in 2021. It is unclear if it will go up or down later.

The health care block had ups and downs from 1976 to 2011. Compared to its typology in 2016 and 2021, it is rising. After interviewing the council in Health Village area, it will have a lot of demand for senior citizen’s facilities. This can be a hot topic for this Market Building in the future.

There is no clear change pattern for Block B- indoor stadium. It is also a new block added to the prototype of this Market Building. It needs more research on whether this block is needed in this building and what sports it will have.
