Re-Imagining Of Shenzhen Gangxia Urban Village

Residential Renewal Masterplan | 2023

Tutor: Amin Taha | RCA. ADS5 | Individual

How do you decarbonise Chinese construction habits while attempting to better living conditions without displacing 70% of the urban migrant worker population; living eight to a room and with wc’s and kitchens in the same room? Government’s and resisted solution has been wholesale demolition. Light weight timber upward expansion before some buildings are decanted, replaced with open public space and taller structures. Increasing the local population by 18%, landowners income and reducing government costs.

THE STRATEGY

01. Classification of buildings, retention of buildings in good condition and demolition of completely lightless blocks. 02. Linking the preserved blocks into bigger cluster to gain more space and Improved the interior layout, Installation of barrier-free facilities such as lifts. 03. Built 3-4 storied lightweight timber structures roof extensions on the preserved blocks and relocated the residents from the removed blocks. New roofs can be connected and turned into new public spaces 04. New roof will be gardens, agriculture, communal and comercial space. After demolition, public spaces can be parks and squares and new tower can be added to further Increase capacity. Figure 1.4 New rooftop of the village unleashes the potential of space.

CHONGQING STATION 02

Train Station Roof Park That Filling The Gaps In The City

High Speed Railway Station | 2022

Tutor: Amin Taha | RCA. ADS5 | Individual

How do you redeveloped a long-deserted railway station in the centre of Chongqing with greener and cheaper materials and restore an entire district? Chongqing Railway Station, located in the Caiyuanba area, was built in 1952. Due to the mountainous terrain, this area has been disconnected from the main urban area and has been in decline for a long time. High-speed railway stations in China are often designed to be grand, isolated, landmarks, and the offical new plan for this site is no exception.

Figure 2.3 Structural section shows how to fix urban spaces

In 2020, Chongqing released a plan to renovate the Chongqing station over the next five years, with plans to build a comprehensive hub centre that will be connected to Chongqing East Station and Chongqing North Station.

The new railway station will be a two-way station with seven platforms and 12 lines, and the size of the station building will be limited to 60,000 square metres.

DOME LIGHT AS A GUIDANCE

The vaulted ceiling opens up to meet the light requirements of the interior and creates a unique atmosphere. The light also acts as a visual guide to the space, suggesting the functional properties of the different spaces and helping passengers to find their way around more quickly.

The rooftop park is connected to the riverfront park pier and the hillside, with a hiking trail and fast direct access to the city lift, which greatly enhances the connectivity of the area to the main city, while the new separate entry lane alleviates the traffic pressure in the area.

Alternative Materials For Airport And Big Sheds Typology

Airport | 2022

Tutor: Amin Taha | RCA.

ADS5 | Groupwork

We are in a climate emergency. The construction industry contributes an estimated 40% of total carbon emissions in the world annually. 11% of which resulted from manufacturing materials and products such as steel, cement and glass, which has always been the superior choice for airport construction. With these two facts in mind, this research investigates the methods and envirionmental impact of the biggest airport terminal in Spain:Terminal 4, Barajas Airport. Through a detailed analysis of the existing condition, we propose alternative solutions that are both econimcally viable and radically better for the environment.

Terminal 4, Barajas Airport, designed by Rogers Stirk Harbour + Partners and Estudio Lamela, is a typical modular design building constructed mainly of steel and concrete. This project uses a typical Structural bay of the terminal as a research module.

Through this research, we have concluded that by changing materials and construction methedology it is possible to build a carbon copy development of that proposed by Rogers Stirk Harbour + Partners that is faster, cheaper and greener.

We have investigated four options, two carbon copies and two what if...options to assess which method is the greenest, fastest and cheapest. Our investigations show that with extended thinking about material qualities, Structural feasibility and detail node construction that it is possible to build carbon copies of the Barajas Terminal 4 that are cheaper and greener.

Carbon copy B uses mainly stone, making it almost a zero embodied carbon solution. Theoretically, stone can be used half of the volume compared to the existing building which can help reduce almost half the price and make it the best choice in carbon copy.

KING BOAT CEREMONY 03

Carnival Masterplanning To Rejuvenate A Dying Custom (competition First prize)

Carnival Masterplanning | 2019 - 2021

Competition | Xiamen University | Individual

Apart from sealing our traditional culture into a gallery, how can it be truly remembering and celebrating? In this competition, the organisers asked us to design a Museum in the Shapaowei community to honouring the culture of “King Boat Burning Ceremony”, which is an ancient regional tradition that is currently disappearing as the urban renewal takes place. The real danger comes from the fact that the younger generation is no longer involved in such traditions; how can rituals be re-imagined to preserve the memory of traditions and engage young people?

I have planned a festival carnival in turning the original customs into a series of activities to catch young people’s attention and participate in it, according to the process route of the ceremony, I selected four site as the hosted sites, and designed a series of space for the carnival. Part of the space is designed as modular and can be used in different sites, so that it can move with the process of the festival ceremony.

HERITAGE CRISIS IN THE SHAPOWEI COMMUNITY

“King Boat Burning Ceremony” It is a sacred custom popular among the Tankas ”People living on boats“ It is a belief custom for Tankas to pray for peace and harvest by worship the sea gods in the form of “burning boat by the sea”.

As a Tankas’ settlement, Shapowei is the core ceremony area. In recent years reconstruction, the traditional fishing port has reformed as commercial street, which occupyed traditional customs hosted space, traditions are disappearing in this region.
