The site is situated at a deep slope with more 11m level differences that it blocks certain amount of daylight from the south of the cliff of Kennedy Road; the site houses a majority of 4-5 storeys TANGLOU that g/f consists of a mixture of car maintenence stores and pubs. Although there is no public housing built in surrounding area, low income class is hidden inside the subdivided fflats of TANGLOU.

Social Sustainability A centerpiece of the project is social and cultural diversity. In addition to the 20% subsidized apartments another 10% of all apartments are reserved for charity and non-profit foundations supporting handicapped people, immigrants, students and children under child-welfare. : All tenants are invited to play an active role in shaping the community. Common spaces and an annual budget of CHF 80000 from the solidarity fund are at the tenants’ disposal for community initiatives, such as cooperative-contract-farming, grocery shop, repair café, swapping place, dancing, playing or practicing yoga together, offerings for children, common gardens, German teaching group, co-working space and more. 10 non-commercial common spaces are available for all inhabitants. Their usage was defined by the inhabitants and most are are open to the public. For some initiatives we partner with public organisations e.g. in youth work or support for elderly people.

Background
E P
Pixel is the f irst project under construction in Makers District, a new development on Abu Dhabi’s Reem Island that is billed by developer IMKAN as the new heart of Abu Dhabi, providing a creative counterpart to the city’s cultural hub on the nearby Saadiyat Island. Capitalising on the innovative, cosmopolitan spirit of Makers District, Pixel is envisioned as a development which embraces the outdoors and creates a sense of community, deviating from the prevalent typology in the United Arab Emirates of disconnected towers.
T
Intended to serve a diverse mix of residents and visitors, the design features a wide range of distinct spaces and roof decks that come together to give the development a “village-like” feel. Targeting young start-ups entrepreneurs, a large number of small (50-square-meter) commercial spaces will be available to rent, while a number of the residential units will feature large terraces on lower levels (instead of a typical rooftop terrace) to allow users to interact with the plaza below.

Reflection After the conceptual and density massing studies, I focused on the massing ideas of neighbourhood, tulou and box intersection types since I was more interested in shaping a good neighbourhood atmosphere for social interaction. In order to have a certain degree of density shaping the sense of neighbourhood but keeping a control on building height, the building shall remain around average of 10-12 storey.

Analysis There are only six open nullahs left in Hong Kong. People tended to avoid constructing any buildings close to the nullah due to the smell, otherwise, there will be a buffer of park or roadway to separate the nullah and buildings. Only few housings are found to be relating to the nullah. Contrasting to avoid the nullah, I would like to explore more on any possibility that housing can work with the nullah to gain a new supply of land.

History In the 1840s, people were building houses along the nullah to use the water washing clothes and childern were having fun with the water. However, due to car trafffic demand and smell problem the nullah was closed in 1960s. Though, the name of Stone Nullah Lane keeps its own history till now and to the future.

HK NULLAH CASE STUDY Kai Tak Nullah Re-development (2020) The existing Kai Tak Nullah is about 2.4 km in length. It flows from Po Kong Village Road along Choi Hung Road, pass Tung Tau Estate and San Po Kong, into Kai Tak Development Area before discharging into the Victoria Harbour. - reconstruction and upgrading of Kai Tak Nullah of about 1 300 metres (m) long at the north apron area of the former Kai Tak Airport from Prince Edward Road East to Kai Tak Approach Channel into a combination of a drainage channel and multi-cell box culverts with a total width varying from about 40m at the upstream to about 70m at the downstream;

- construction of two enclosed desilting compounds with vehicular access; and
N
- ancillary works including landscaping works, environmental mitigation measures and related monitoring and audit works.
C E P T
Nullah Desilting Compounds The Desilting Compounds (DCs) 1 and 2 are key components to maintain the drainage capacity of the Kai Tak River by removing sediments accumulated along the drainage channel and box culverts in fully enclosed buildings. Both DCs 1 and 2 are single-storey building occupying a site area of around 16,000 and 2,500 square metres respectively. CEDD is dedicated to embed sustainable and green elements in the design to promote environmentally friendly design and sustainable development. The design team strove to enhance the visual quality and aesthetics of both DCs 1 and 2 with an aim to creating an impressive building structural form. Bearing this objective in mind, both DCs 1 and 2 are designed to be low-rise premises featuring a modern and streamline design that creates a harmony with surroundings.

Vertical Constructed Wetland Design Constructed wetland is a cheap and easily-operating water treatment method. Due to the increased efficiency a vertical flow subsurface constructed wetland requires only about 3 square metres (32 sq ft) of space per person equivalent, down to 1.5 square metres in hot climates. I attached the idea of using constructed wetland as the nullah to add another layer of thinking into the design.

The focus was on how the nullah can form new public space as a water park, at the same time, engage with the circulation of the housing residences.

.
The design illustrated the inital thought of the combination of a water park and a mixture of neighbourhood situated above the park. However, The residential building design developed was rather too generic at this stage since the building method of prefabricated concrete modules limited the play of building form. Moreover, the connection between nullah and housing is yet to be integrated in terms of their function, meaning and form.

The design of water system is then developed to be integrated with all zones. It becomes the linkage between the diversity of the neighbourhood. The Zone D was reffined as a frame of laboratories relating to water treatment technolgies. However, there is still a need of development for the detail design in each zone. The social space design was also developed to shape distinct character of spatial quality. Due to the comprehensive consideration of Zone F Cube Design that could not link harmonisely both in circulation and functionality with other zones, Zone F was removed but as the social space for Zone B. 34

Housing problem in Hong Kong has been noticeably critical for years. However, the housing differiculty of sandwich class situated at the middle has been belittling. Not only they are having challenging tasks to gain the down payment, they barely receive any housing beneffit but paying a great proportion taxes; Facing the shortage of land to fulffill such housing demand, this project aims to explore the possiblity of an alternative housing model that combining revitalisation of nullah and housing development. The ‘‘housing as infrastructure’’ design model could be tested at other nullahs in Hong Kong in the future.

The proposed design not only could revitalise the nullah and help sandwich class people to gain their own property, but the introduction of the water system on the master planning cultivates a new sustainable living style. Against the Top-down housing model, harmonising the fflow of water and the fflow of human interaction assembles a diversity of neighbourhood that the exchange of knowledge and experiences may help residents to raise up their social class during the temporary stay.

Second-treated Water
All primary treatment plants are situated underground. Water after primarily treated is then pumped to roof with collected grey water. They are then secondarily treated either through the vertical wetland from building facade or by traditional treatment plant in the centre of the site. The water then fflows towards the lagoon as the water tank. The clean water is eventually pumped back from the tank to all buildings through pipes.

Isometric Typical Floor Plan 1:500 (scaled)
Concept Canaland runs along the fflow of the nullah. It features the fflowing stairs that connecting all social space at the land. Despite of that every 16 units share a 5 units size space of social space, with full-equiped kitchen, dining, living space and f lexible workshop space for hosting events, all social spaces are directly linked with stairs as an informal gathering space sitting above the view of nullah. The unitâ&#x20AC;&#x2122;s building facade acts as the vectical wetland for secondary treatment process. The plantings are casted into the concrete facade that the ffliping of openings maxmise the horizontal space for the wetland.

Concept Lagoonland references the ‘‘twin tower’’ idea of old Hong Kong public housing that having a central courtyard to form a secure but connected neighbourhood. My proposed design is to add another layer turning the courtyard into a urban lagoon using the treated water from the site for public and standing a frame of social boxes for residents. Every two storeys share four double celling height social spaces with full-equiped kitchen, dining, living space and f lexible workshop space for hosting events.
49
Lagoonland plays at the start-end role as the water system. The water tank has the capacity to store 2-3 days water needed for residents’ usage. Constrasting to Canaland, building facades in life core at Lagooland are used as vertical wetland for secondary treatment process.

Concept Eraland is the assimilation of the past and the future. It composed the existing heritage of the Blue House and a new water technology laboratories and museum. The Blue House acts as the entance lobby and the exhibiton space of Hong Kong water treatment technology history and new invection. A new lift core in the Blue House then lead people to the fflow of the museum and labs. The maximum occupancy of museum and labs is limited to 55% to ensure suffficient daylight. A traditional water treatment plant sits under the fflowing labs that the cylinder water tanks act more as a lift core serving the users for the labs. The top watching decks sees the entire operation of the water system of the site.
51
The professionals in labs and the workers operate the water treatment plant will live in the housing at the side, where 4 units are sharing an full-equiped kitchen, living and dining space.

Concept Greenland composed with three green houses integrated with the entrance hall of individual residential blocks. The green house is designed to be open at four sides to maxmise the daylight transmission, where two slopes connecting two garden cafes can enjoy a pleasant journey of appreciation of the greenery. Residents are responible to the duty of green house gardening. The grey water consumed by the residents, combined with rain water and stored at the roof will then used for the gardening of greenery.

The design model started with the revitualisation of buried nullah fflow existing for more than 200 years. The introduction of human fflow running
I
along the water fflow not only inherited the strategy of an neighbourhood growth in past, the proposed design brings the human fflow runs into the
N
water fflow. It invigorates the mechanism between human and water. It then cultivates the fflow of experience between humans to intensify
A
the growth of wealth and knowledge. The temporary housing and lab
L
occupancy suggest a continous fflow of human exchange overlapping old and new.
