Revitalising Brownfields Self-Sufficient Transitional Housing by Bamboo Afforestation and Industry

Chan Yeung Chun Thesis submitted to the Department of Architecture In partial fulfillment of the requirements for the Degree of MASTER OF ARCHITECTURE National University of Singapore 02 May 2020 [2nd Edition]

Abstract This thesis aims at striving to address the livelihood issues of the numerous vulnerable in Hong Kong, by designing a fast-built, durable and low-cost medium-high density of bamboo transitional housing and afforesting bamboo plantation for construction materials self-sufficiency on brownfields. The study involves transitional housing module innovation and atpyical urban form, to tackle the social segregation of different families with social characteristics, such as elderly households, singleparent households, new-arrival households, youth households and households with children. The transitional housing involves the strategic use of brownfields in New Territories, misused fragmented former agricultural lands between the urbanised area and traditional rural settlements, in order to expand its proximity to the context with traditional culture and neightbourhood harmoniously, to achieve the future model of brownfields revitalisation.

Keywords: Transitional Housing, Brownfields, Bamboo Afforestation and Bamboo Structure.

Introduction The worst scenario of Hong Kongâ&#x20AC;&#x2122;s housing shortfall is yet to come. The amount of public rental housing completions is set to plunge in the coming decade, whereby the median multiples of housing affordability have reached a new peak and average waiting time for public rental housing for general applicants has risen to 5.5 years notoriously. To mitigate the livelihood issues of the grassroots and influx of immigrants from Mainland China, the Government is urged amid the looming housing crisis by allocating poverty to transitional housing.

Hong Kong is not deficient in land resource but lacking efficient use of lands. Brownfields site, former agriculture land in New Territories converted to other uses, such as warehouse, open storage, container yard, and open vehicle parking, is a case of inefficient use of lands. Brownfield sites have great proximity to rural settlements in New Territories, where are mostly well-equipped with transportation system. Brownfields is undoubtedly a potential location to situating the transitional housing, to provide the residents with a coherent relationship with the surrounding neighbourhood.

An urgent and great need for temporary transitional housing supply implies a low cost, durable and rapid construction system and technique needed â&#x20AC;&#x201C; bamboo structure. Proposing bamboo afforestation on brownfields not only provide transitional housing project with primary bamboo resource and secondary products, but also remediates the soil by carbon sequestration and revives the forgotten greenery on brownfields among the rural settlements. Along with bringing back economic values to brownfields, bamboo grove becomes a linkage, such as park and open space, to significantly create a coherent integration between the residents and context.

Chapter One

Housing Crisis in Hong Kong Worsening housing shortfall in Hong Kong

incurs undesirable livelihood issues from the grassroots. The poverty crams into tiny cubicles due to the high rental cost and unaffordability of housing market. The shortage of public rental housing (PRH) supply results in a long average waiting time for public housing allocation. That is why transitional housing is an urgent need for the coming decade.

“New Residential Unit Completion is set to plunge in coming decade.” 1.1

Housing Shortfall

In 2018, the Hong Kong housing market is comprised of 44.8% of public housing, 54.6% of private flats, and 0.6% of temporary housing (HKHA, 2019a) . The number of public rental housing (PRH) and subsidised sale flats (SSFs) are accounted for 29.1% (808,000-Unit) and 15.7% (400,000-Unit) of the amount of public housing supply respectively (Figure 1.1). Compared with Singapore’s public housing condition, the proportion of HDB to private residence is 8:2. 82% of Singaporeans are living in public housing. Housing shortfall started in 2002. The first executive of HKSAR stopped building SSFs due to the prevention of property prices to slump during the Asian financial crisis. The average annual housing completion slid from 59,800 to 25,700 units, by over 50% drop between 2007 and 2016 (Figure 1.2), which leads to the growth of the total number of PRH applicants (Task Force on Land Supply, 2018a).

According to Long Term Housing Strategy (LTHS) Annual Progress Report 2018, the target of public housing supply is 290,000 units from 2015-2016 to 2024-2025. Nonetheless, only 192,000-unit will be completed, which means there is a 97,800-unit PRH shortfall in the coming decade (Table 1.1)(Ip & Poon, 2019).

“Hong Kong housing is still the world’s least affordable for the ninth straight year.” 1.2

Housing Affordability

Hong Kong housing market is the world’s least affordable one in the past nine years (Performance Urban Planning, 2018). Hong Kong’s Median Multiple has soared to 20.9 and 18.1 among major markets and very-large markets worldwide (Figure 1.3 & 1.4), and far outweighs all other property markets and severely more unaffordable. Undoubtedly, the high Median Multiple is a consequence of housing supply shortfall and inclination to developers on land policies. The Governments generate an enormous amount of revenue from offering lands to developers, so as to keep the taxes low for providing a desirable business environment for entrepreneurs. It is criticised that, “Hong Kong housing is built to serve the market, not the people.”(Chan, 2018).

“The average waiting time for general applicants stands at 5.5 years.” 1.3

Average Waiting Time for PRH

In mid-2019, Hong Kong Housing Authority (HKHA) accumulatively received 147,900 general application of PRH. The average waiting time for the general PRH application is 5.5-year (HKHA, 2019b) (Figure 1.5). Worse still, the average waiting time for the non-elderly one-person applicant can reach 10-year under the annual quota for allocation. Influx of immigrants from Mainland China is also a factor of long average waiting time for PRH. Although HKSAR has a high level of autonomy based on basic law, HKSAR is unable to control a quota of 150 immigrants a day permanently settling in Hong Kong from Mainland China, with a One-way Permit issued by the People’s Republic of China (Home Affairs Department, 2019). The population growth of newarrivals in Hong Kong is about 50,000 new-arrivals every year and accumulatively 265,000 new-arrivals from 2004 to 2016.

Cubicles of Shame

Considering that the low-income citizens cannot rent a private flat or rent-to-rent public housing due to high rental cost (Figure 1.6) and waiting for allocation of PRH, they have to live without dignity – living in a subdivided unit. The Thematic Report: Persons Living in Subdivided Units (SDUs) in 2016 reveals 209,700 people living in 92,700 SDUs in Hong Kong. For example, a subdivided apartment is commonly 80-200 square feet, with a shared toilet, which costs HKD3,500-6,000 monthly. The cage homes or coffin cubicles are even worse, which are about 15-20 square feet, can just fit a 4 feet bed, which cost HKD1,500-2,500 monthly (Figure 1.7). Hong Kong used to provide them with transitional housing, but all of them have been demolished due to land resources of new development areas and the Government’s underestimation of housing. Why not reestablish transitional housing? Where can the Government site transitional housing in a condition of alleged “land supply shortage”? The next chapter shows you the potential option.

Chapter Two

The Brownfields and Rural Settlements The Government constantly alleges the housing shortage is a result of lack of land resources and therefore, the Government plans to obtain more lands from the periphery of country parks and land reclamation, which received instant criticism from NGOs and the public.

Nevertheless, Liber Research

Community, an NGO undertaking independent research of the development in Hong Kong, revealed more than a thousand hectares of brownfield sites were identified. These sizable brownfield clusters were undercounted by the Government, which is a potential land resource for the upcoming housing supply.

Definition of Brownfield

The definition of brownfields in Hong Kong refers to former agricultural properties being converted to other uses due to the decline of agricultural activities (Task Force on Land Supply, 2018b). Brownfield sites are idle or vacant and commonly converted to Container yards, outdoor vehicle parking, open storage/ recycling, covered warehouse and filled/destroyed land (Figure 2.1). Compared to the definition of brownfields in other countries, brownfields in the United States indicates the expansion, re-development or reuse of properties might be complicated by the potential presence of special hazard of contamination (EPA, 2019); brownfields in the United Kingdom refers to developed properties or premises subsequently become idle, derelict or polluted (Politics.co.uk, 2012). 2.2

Distribution of Brownfields

1,172 hectares of brownfield clusters are identified, and span across the New Territories, mainly in Yuen Long District, Northern District and Tuen Mun District (Figure 2.3)(Liberal Research Community, 2018a). Brownfields being included in existing development projects or having a development timetable accounted for 62%, where the New Development Areas (NDAs) are Hung Shui Kiu NDA, Yuen Long South NDA, Ping Che NDA and Fanling North NDA (Figure 2.2). On the contrary, more than a third on brownfields have been excluded by government development plan(Figure 2.4), on the grounds of allegedly “fragmented and scattered pieces of land.” Brownfield clusters are not fragmented and scattered. The 7-top clusters of brownfields were identified as over 30 hectares each, cumulatively 548.3 hectares. Brownfield clusters less than 5 hectares and 5 to 10 hectares were found to be over 42 pieces (133.5 hectares) and 26 pieces (176.9 hectares)(Figure 2.5). A large amount of land parcels is located in the periphery of the new town area, which is the potential for middle to high-density development mode.

2.3

Mishandling of Brownfields

Most of the brownfield clusters had not been handled in priority by the government, which resulted in a severe expansion of brownfields towards agriculture lands, village-type development lands and preserved green belt (Figure 2.6). Two types of brownfields namely covered warehouse/workshop and open storage/ recycling had increased drastically from 1993 to 2017, to 650 hectares and 500 hectares respectively (Figure 2.7). Currently, covered warehouse/workshop and open storage/recycling are also accounted for the majority of brownfields, 42.6%, and 32.6% respectively. Open vehicle parking, filled/destroyed lands and container yards are accounted for about 8% each(Figure 2.8)(Liberal Research Study, 2018b). The reason why brownfields’ expansion being out of controlled and mishandled by the government, was the government lost its lawsuit from “Attorney General v Melhado Investment Ltd. CACV79/1982, [1983] HKLR 327”. The High Court ruled that the use of land listed in the schedule in the Block Crown Leases for the rural New Territories, was “descriptive only and no implied covenant of the type contended for” and only the unauthorised structure, buildings and clamorous, offensive and noisome activities were forbidden(Legislative Council & Panel on Planning, Lands and Works, 2017). Thereafter, those uncultivated agriculture lands were converted to brownfields among the rural settlements. 2.4

Proximity to Rural Settlements

Brownfields are potential for residential development because they are located in the middle of nowhere, whereas brownfields are located in the periphery of the developed new town and have high proximity to existing rural settlements in New Territories (Figure 2.1). The rural settlement environment and fabric would become a significant context for the transitional housing proposal on brownfield sites. Rural settlements vary from villages to small towns, mainly distributed in New Territories. The indigenous villages were delineated the under British Colonial Government after the New Territories being leased to Great Britain for 99 years in 1898. The descendants of the original inhabitants are still living in the remaining historical walled villages, or new-built villa-style building, called “Small House”.

The New Territories Small House Policy was implemented in 1972, which entitles one concessionary grant for an18-year-old New Territories male indigenous villager descended

through the male line from a recognised indigenous village since 1898, to build a Small House (Fowler, 2018a). An exemption is permitted under the Building Ordinance (Application to New Territories) if the Small House has fulfilled the spatial parameters, such as a height of no more than 3-storey and 27-feet, site coverage area not exceed 700 square feet, etc. (Figure 2.9).

Some indigenous inhabitants improperly sold their concessionary rights and lands to the developers for profits over the decades. More than 1,000-hectare of agricultural lands held by major developers in Hong Kong for land reserves, for future profitable residential development after getting the permission of change of land use and development parameters from the relevant authority.

Chapter Three Bamboo

In Hong Kong, Bamboo is common construction material for temporary structure due to its appeals, such as inexpensive cost, fast construction, durability and intensive renewability. The high flexibility of bamboo structure is one of the potential construction methods for transitional housing, so as to cater to diversified and varied groups of residents for transient dwelling environments.

“The upscaling bamboo production technologies provide various types of engineered bamboo products .” 3.1

The Use of Bamboo in Hong Kong

The temporary bamboo structure can be classified into constructional use and traditional use. Hong Kong construction industry is renowned for its speedy and efficient bamboo scaffolding techniques (HK Magazine, 2018). Compared to steel, the lighter weight of bamboo allows scaffolders six-time faster to erect and 12-time faster to dismantle . Currently, there are more than 1,500 registered bamboo scaffolders and 200 scaffolding companies are operating this diminishing profession. Temporary bamboo structure is also used for Chinese festivals and traditional events, for instance, bamboo opera theatre and flower plagues for celebrations of Lunar New Year, Hungry Ghost Festival, Tin Hau’s Birthday, Cheung Chau Bun Festival. Temporary bamboo structure and flower plagues can be discovered in the events of babies’ hundred-day banquet, wedding in traditional villages or business opening in Town. 3.2

Mechanical Strength Properties

Bamboo has good adaptability and strong mechanics. It has a tensile strength as steel, compressive strength as concrete and high bending strength as well (Figure 3.1)(Gutu, 2013). Currently, the upscaling bamboo production technologies have been adapted to provide various types of engineered bamboo products made of a wide variety of extracted raw bamboo poles, such as bamboo laminated board, woven strand board or particle board, etc. (Figure 3.2)(Böck, 2017). In addition, the lifespan of bamboo pole materials has been extended to more than 50-year after applying an appropriate treatment, while the life of natural bamboo is less than 2-year (Schröder, 2014).

Ecological Benefits of Bamboo Afforestation

Converting brownfields to the bamboo plantation by afforestation to remediate the soil of brownfields, meet construction materials demands, bring back greenery and economic values to brownfields, is one of my thesis strategies. What does bamboo benefit to the environment? Bamboo is an evergreen species in the subfamily Bambusoideae which is part of the grass family Poaceae. It grows rapidly, even in degraded land. Carbon sequestration, a process of long-term carbon sink can be effectively created by underground biomass of bamboo’s rhizome system (Edwards, 2017). The rigid and dense rhizome system is also an excellent soil stabilising feature. That is why bamboo can grow in degraded land, remediate and restore the soil nutrients by carbon sequestration. According to the life-cycle analysis of engineered bamboo products, if the carbon sequestration advantaging for afforesting degraded lands with bamboo and being credited from land-use change in the same region is taken into account, the four main engineered bamboo products could achieve negative carbon footprint , and far lower than other energy-intensive materials pertaining to the technological cycle (Figure 3.3, 3.4 and 3.5)(Lugt, 2017).

Concept of 1-hectare of Bamboo Plantation

Before calculating how many bamboo poles can be produced if bamboo afforestation is implemented in New Territories, a study of 1-hectare of plantation is conducted. For standard density and medium density of plantation, it is recommended 400 and 1,500 clumps are planted on a 1-hectare plantation. Each clump of bamboo grows more than 30 bamboo poles every year. 5 mature poles could be harvested per year based on conservative calculations. Based on the standard density of plantation, harvesting activities could start from the third year and a stable number of 2000 of mature bamboo poles, ranging from 6-14 cm diameters of bamboo poles annually after the fifth year (Table 3.2)(Eco Bamboolot, 2013). According to a medium and large scale bamboo plantation study in China, the accumulative net present value of bamboo afforestation could reach RMB48,487 per hectare (Table 3.1, 3.3)(Xiao, 2001).

Chapter Four Design Parameters

In Chapter Two, the research shows that brownfields excluded from government development projects are accounted for 448.5-hectare, 38% of the total area of 1171.5-hectares of brownfields. This Chapter is going to explore the area allocation proportion for transitional housing and bamboo afforestation.

Figure 4.1 Residential Densities in Rural Areas

4.1 Required Total Domestic Area for Transitional Housing Before calculating the area required for alleviating 97,800-unit public rental housing shortfall, the permission of residential density relaxation needs to be acquired from the Planning Department. In New Territories, residential density is categorised into “New Town Residential Zone” and “Rural Area Residential Zone”. Brownfields are mostly distributed in the agricultural or village-type development lands in the rural New Territories and therefore, only six Rural Residential Density Zones, ranging from RR1 to RR5 and villagetype are available for brownfield sites. To maximise the residential density and development potential, such as plot ratio and building height, RR1 and RR2 are recommended for transitional housing development, which relates to “medium-rise residential block with up to 12 floors including at most two commercial lower floors” and “low-rise residential block with up to 6 floors and no commercial elements” respectively (Figure 4.1)(Hong Kong Planning Department, 2016). 4.2

Site Area Proportion of Transitional Housing to Bamboo Plantation

To cater to the same amount of 97,800-unit public rental housing shortfalls, 5,496,300 square-meter of the overall domestic area needs to be provided for transitional housing in Hong Kong. This figure is based on the ratio of existing size of households and ideal living space for different sizes of households (Table 4.1). To allocate 5,496,300 square-meter of the total domestic area with rural residential density category RR1 (Plot Ratio 3.6), 35% and 65% of brownfields excluded from government development project would be distributed for construction of transitional housing and bamboo afforestation respectively (Figure 4.2). 4.3

Annual Bamboo Poles Production

From the above calculation, it is known that about 291-hectare of brownfields is planned for bamboo afforestation. According to the concept of 1-hectare of bamboo plantation in Chapter Three, a stable number of 595,960 of mature bamboo poles on average, ranging from 6-14 cm diameters of bamboo poles can be harvested annually after the fifth year (Table 4.2)(Eco Bamboolot, 2013).

Typology Invention of Transitional Housing To alleviate the public housing supply shortfall and long average waiting time, transitional housing becomes an urgent need for povertyâ&#x20AC;&#x2122;s livelihood.

5.1

Case Study of Social Housing Six case studies are conducted for the understanding of various aspects and considerations on social housing worldwide. The six case studies as below:-

Sejima Wing, Gifu Kitagata Apartment Building, by Kazuyo Sejima (Figure 5.1)

Hawley Wing, Gifu Kitagata Apartment Building, by Christine Hawley (Figure 5.2)

Trellick Tower, by Erno Goldfinger (Figure 5.3)

Dortheavej Residence, by Bjarke Ingels Group (Figure 5.4)

Carabanchel 11, by Morphosis (Figure 5.5)

Transformation of 530 Dwellings, by Christopher Hutin (Figure 5.6)

The planning of traditional transitional housing in Hong Kong used to be ruthlessly uniform, inflexible, compact and environmentally dysfunctional. The case studies guide the thesis to create a new typology of transitional housing, to cater to different social characteristics of vulnerable groups, provide them with a wider range of atypical internal planning and volumetric arrangement, and circulate the residents laterally and vertically through communal space strategically.

Demography Under Poverty Line

In prior to further study on typology invention of transitional housing, research on the demography of people living under the poverty line is conducted (Figure 5.7). There is 1.37 million poor population, with 1 in 5 people considered living below the poverty line (Lam, 2017). The poverty could be categorised into five groups by the social characteristics, Comprehensives Social Security Assistance (CSSA) households, elderly households, single-parent households, new-arrival households, households with children and youth households (Census and Statistics Department, 2017). The data of types of household size, ranging from 1-person household to more than 6-person household, is also significant information for the proposed numbers of different household size and social characteristic groups in transitional housing (Table 5.1). 1 -Person

Site

The site selection for thesis is located in Ping Shan, New Territories (Figure 6.1). The site comprises fragmented brownfields, for instance, vehicles, coaches and truck parking, garage and squatter structure, which are misused land resource on village-type development land use (Figure 6.2). The site is adjacent to three indigenous villages with Ping Shan Heritage Trail and has a close proximity to Tin Shui Wai New Town and future Hung Shui Kiu New Development Area with well-equipped transportation. These are the significant elements of social integration for the residents living in the proposed transitional housing.

Conclusion Hong Kong is not lacking in land resource, but deficient in an efficient land management. Having the great proximity to indigenous villages and the periphery of new towns in New Territories, brownfield sites are the potential land resource for re-establishing transitional housing for the vulnerable living below the poverty line and afforesting bamboo plantation for self-reliant construction materials for the transitional housing, other than land reclamation and developing country parks.

The strength, flexibility, rapid growth cycle of bamboo makes it as the most environmental conscientious construction materials for the proposing self-sufficient transitional housing. Bamboo afforestation on brownfields also revives the economic values of lands and local employment opportunities. Also, bamboo afforestation and its soil remediation transform brownfields to a lush urban greenery, recreation, health and well-being for the residents and neighbourhood.

Re-establishing transitional housing on brownfields alleviates the livelihood issues of the poverty by providing them with employment opportunities from engineered bamboo industry and existing new development area. The communal role of the revitalised brownfields acts as a significant platform to connect people from variety of backgrounds and profiles, through social gathering and participating in the traditional festive celebrations and ceremonies in the vicinity of indigenous villages.

Accommodating the vulnerable in the proposed in the transitional housing not only saves them from darkness and hopelessness, but also promote a self-reliant livelihood, healthy well-being and socially inclusive community, in order to cultivate their sense of security, belonging and coherence. Before being allocated to the public rental housing, the transitional housing complex on brownfields becomes their home, where they inhabit in, they contribute to. Letâ&#x20AC;&#x2122;s revitalise the brownfields!

(RE)ESTABLISHING TRANSIENT DWELLINGS AND AFFORESTING BAMBOO PLANTATIONS

The worst scenario of Hong Kong’s housing shortfall is yet to come. The amount of public rental housing completions is set to plunge in the coming decade, whereby the median multiples of housing affordability has reached a new peak and average waiting time for public rental housing for general applicants has risen to 5.5 years notoriously. To mitigate the livelihood issues of the grassroot and influx of immigrants from Mainland China, government is urged amid the looming housing crisis by allocating the poverty to transitional housing. Hong Kong is not deficient in land resource but lacking of efficient use of lands. Brownfields site, former agriculture land in New Territories converted to other uses, such as warehouse, open storage, container yard and open vehicle parking, is a case of inefficient use of lands. Brownfield sites have a great proximity to rural settlements in New Territories,

The Small House Policy is a legacy of the British colonial government. In order to cater for the needs of an increasing demand for housing and to prevent another 1967 Riots, the outbreak of which was partly due to people’s discontent towards the indifferent attitude of the colonial government toward public welfare, threatening the colonial

Melhado Case: The Birth of Brownfields Image Source: South China Morning Post

The High Court ruled in the “Melhado” case that lots granted under the BGLs are subject to no restriction on the use of land, other than the clause preventing “Noisome or Offensive Trades”. In other words, so long as the development does not include any buildings, the agricultural lot owner under BGLs may use the land for purposes other than agriculture.

Initiated in 2012, the housing project aims to develop 17,000 public housing units in three phases. Phase 1 refers to ongoing development of 4,000 units in a “green-belt” site; while phases 2 and 3 refer to the deferred plan to build the rest of the targeted units in the “brownfield” site. After government consultation, the proposal only included the plan to build 4,000 public flats on the green belt site, with

In the early 1980s, 13 sections of demarcation districts of farm land in So Kwun Wat, New Territories were abandoned and were rent by Melhado Investment Ltd. and used extensively for open storage of steel girders. The Crown objected that such use was contrary to the terms of the Crown lease. The land had been included in a Block Crown Lease granted in 1905. In a Schedule to the lease the use of each lot was described as it then was.

It was argued that there was an implied covenant in the lease against use of the land for any purpose other than that for which it was used at the time the Crown lease was granted. The decision of the Court of Appeal is well known that the use of the land as listed in the Schedule to the Block Crown lease is descriptive only and has no effect on the restriction of land use. It was held that the purpose of the Schedule was to identify the lands to which the lease related.

Background Initiated in 2012, the housing project aims to develop 17,000 public housing units in three phases. Phase 1 refers to ongoing development of 4,000 units in a “greenbelt” site; while phases 2 and 3 refer to the deferred plan to build the rest of the targeted units in the “brownfield” site.

Average annual growth rate over the past 5 years: 0.4%

Background

Although the permit is specifically for the purpose of family reunion, not for general immigration, the scheme is controversial. Hong Kong currently has a quota of 150 people per day and the waiting time for spouses is currently 4 years. The scheme is alleged that beneficiaries are at the sole discretion of the PRC government and outside of the vetting procedures of the Hong Kong Immigration Department, is an infiltration mechanism by spies and friends of the regime into Hong Kong; those that are not filled by spies become a graft mechanism for officials.

Distribution of Brownfields and Rural Settlements in New Territories

An urgent and great need of temporary transitional housing supply imply a low cost, durable and rapid construction system and technique needed – bamboo structure. Proposing bamboo afforestation on brownfields not only provide transitional housing project with primary bamboo resource and secondary products, but also remediates the soil by carbon sequestration and revives the forgotten greenery on brownfields among the rural settlements. Along with bringing back economic values to brownfields, bamboo grove become a linkage, such as park and open space, to significantly create a coherent integration between the residents and context.
