ADS9: Aura - A Call for An Open Architecture

Born and raised in Hong Kong, this year was exceptionally heart-breaking to see the city going through social unrest and vast political changes. This unprecedented times had me thinking more about the values and identity of Hongkonger, especially the relationship between the built environment and people across generations.

This year, my thesis research stem in two ways; a personal historic account on my family house in Hong Kong, and a volunteering group Fixing HK, formed after the Umbrella Movement in 2014. Both reflect how domestic spaces were shaped through constantly redefined kinship and values, which were heavily influenced by the socio-political environment of Hong Kong since colonial times.

I believe that domestic space is an epitome of the city, which enables one to read common norms of the time, from cultures, rituals to gender roles. It is also a powerful device to frame lives and facilitate new affiliation between people, the neighbourhood and the city. The project shown below is my proposal of an ‘anti-typological’ housing, an alternative way of collective living to the existing high-rise flats.

Learning from Hong Kong protests in the recent year, it is important to gather like-minded people, to bring the localism ideology into daily life and find ways to engage the new era. Especially in uncertain times like now, demonstrating and preserving local cultures and values that generations of Hongkonger hold dearly and proud is above all else critical. 

Sectional Perspective in Context — To enhance the wind channelled from the surrounding buildings, the building across the site is generally lower and flatter. Lightness and fluidity of space and structure create a less claustrophobic atmosphere for living.

Stratified Inhabitation — The terracing form provided open space on each level, also created open canyons and sheltered voids across the site for individuals to gather in any weather condition. Small shops and markets are lined on the street level, which culturally are places of casual interaction and neighbourhood exchange.

Infrastructure for Living is a series of undulating terraced platforms and canopy for co-dependent living in Hong Kong. The project was inspired by the Umbrella Movement back in 2014, the first large scale protest that people of Hong Kong mobilized urban infrastructure into spaces for collective activities to voice demands. Protesters blocked the main traffic and squares with non-violent barricades such as tents and make-shift furniture, domesticated public spaces that were not intended to dwell - for more than 3 months. This lifestyle and temporary structures were maintained by everyone, with individuals taking up roles of their expertise.

Bringing the Occupy experience to daily life, a neighbourhood-based volunteer group, Fixing Hong Kong was formed. Volunteers would go to people’s homes and help them fix home appliances, which ownership of space was redefined by this new mode of co-dependence learnt from the Occupy. They also use urban spaces in a very fluid way, treating existing buildings and spaces as infrastructure, disregarding its original purpose; such as hosting movie screenings on rooftops of apartment blocks and forums on the street.

The 53,000sqm site is situated in Kwun Tong, Hong Kong, a gentrifying district that was densely built-up with a mix of older residential blocks - Tong Lau and high-rise apartment towers. Surrounding the site, wind is greatly reshaped by the cityscape, hence the building enhances airflow and reduces accumulative heat through terracing and aligning living spaces parallel to the direction of the incoming breeze. Approached from all directions to the inner streets, open staircases lead up to all levels of the collective living platforms, loosely divided by parallel walls. There are no static interiors or rooms, only mattresses enclosed by curtains. Other infrastructures for living such as sinks, kitchen and washing cubicles are in the form of loose furniture, shared among the dwellers, to adapt to different social settings and group sizes. Between these clusters of terracing platforms form open canyons and sheltered voids; larger communal spaces facilitate community interactions from grocery shopping to the celebration of festivals. Partially protected by a wind-sensitive textile canopy, the aura of temporariness is demonstrated through the constant change of light and shadow, dependent on external weather conditions. As the wind blows, shadows cast on the platforms and inner streets scatter.

The project departs from these unfamiliar spatial settings and newly emerged way of informal living, to search for an ‘anti-typological’ living alternative to the existing high-rise housing in Hong Kong.

Spatial Phenomenon — The soft rustling of the canopy and changing patterns of light infiltrating through changes the atmosphere of the building passively through wind turbulence dependent on the city fabric.

Massing in Context — The blocks are shaped and arranged in line with the airflow pattern influenced by the surrounding cityscape. The undulating form is integrated with a continuous canopy of textile pieces with varying transparency, changing the light and shadow cast on inner streets and living spaces when the wind blows across.

Roof Plan of Textile Canopy — The undulating canopy embraces the terraced platforms and spreads with the topography, dissolving towards the site boundary.

Terraced Platforms and Wind Pattern — The building is approached from all sides of the city, following the wind corridors extended from the existing to form interlinking inner streets. Living blocks are accessed by open staircases along both sides of the blocks, connecting the streets across levels, all the way up to the rooftop.

View Across Open Canyon — Following the open staircase, collective living spaces are platforms terracing above the street level. Smaller platforms sitting on the edges are varying heights of tables and chairs, also serving as extended decks to visually connect people across levels and blocks.

Inhabitation Plan | R/F - 3/F - G/F — Facilitating the airflow, there is no static interior or rooms, mattresses for sleeping are enclosed by curtain, located at the back of the platforms, where it is darker and less visible from the outside. Dwellers come from all places as individuals, but share infrastructures such as sinks, toilet and washing cubicles.

Build-up Sequence of a Block

Build-up Sequence of a Block — The structural system of the building is similar to that of a stadium, with reinforced shear walls as the main structure. Thin platforms are cast with corrugated steel plate and concrete. Smaller platforms sit on the edges as plinths. From an external angle, only activities in the outdoor collective spaces are visible. These exposed spaces including the rooftop, are partially shielded with an undulating canopy, supported by a wall and cable system, hanging textile pieces of different sheerness to flicker with the wind.

The experimentation of canopy began by looking into rippling of surfaces and also fabric and textile forms against wind. Wind is a continuous energy travelling through, which reacts specifically to stiffness and translucency. The organic and unpredictable surface is brought on and broken up into smaller pieces that are densely packed together. Altering the material translucency and density, the surface form brighter, open patches and darker opaque areas. Pointy geometry of the pieces also formally give a sense of direction, as opposed to a softer geometry. Materiality extremes were further stretched here, rounder textile pieces catch more energy and are more reactive to wind, hence more dynamic light and shadow flickering with higher wind speed.
