In the twenty-first century, we are witnessing the increased uncertainty in our
living environment. The fragility of our existing socio-economic system, reflected
in the form of the built environment, is being exposed as climate disasters become
a commonplace. There presents itself a need for human resiliency against the
unpredictable nature of our planet. By incorporating mechanical and passive
sustainable systems in the architectural design, the Institute of Hydrogen seeks to
combine production and research of hydrogen as an alternative energy source to
our current carbon-intensive economy.
Reversing the tendency to hide all its mechanical systems in modern construction,
the institute integrates them as spatial experiences to educate the visitors on
the production and usage of green hydrogen. Research and living spaces are
interwoven with agricultural gardens and hydrogen production tanks to create a
winding path along the slope of the hilly site. A myriad of sustainable strategies
are deployed to deal with the superimposition of the water-energy problem in
Arizona. The result is a series of expansive south-facing butterfly roofs covered
in photovoltaic tiles to generate energy to be stored as hydrogen, while its northfacing
counterparts direct rainwater to the center gutter for collection. In contrast
to the alien spaceship quality of Biosphere 2, the Institute of Hydrogen tries to stay
close to the soil and be respectful to the land it occupies.

alternative aggregates and
additives like coffee grounds or
copper slags are proposed to be
added to the concrete mixture.
This will reduce the use of carbon-

Jonathan Chu
Ingrid Pelletier
Sunnyside in Queens, NY is an emergent neighborhood with a high proportion
of transient and immigration non-households. The neighborhood, with its relative
cheap rent and easy access to the 7 subway line is a popular spot for a new comer
of the city to establish themselves.
The 7 line presents an opportunity with its high number of unused FAR below and
along the line. The subway acts as a conduit to accumulate FAR in a bank that
incentivize private developers nearby to develop along the corridor, promoting a
future of transit-oriented development.
Queensbound Collective is a vision for one of these hubs by incorporating
elements of indoor recreation, religious, cultural, and transport facilities under
one single roof. The extra FAR is used to address the affordable housing crisis by
rethinking the 80/20 split of the existing Mandatory Inclusionary Housing System.
It forsees a new form of collective housing that is based on income and family size
of the tenants, and grow with them as they eventually become successful to move
to other parts of the city.

Special Zoning District
Queens, NY
The 7 train connecting Flushing,
Queens with Midtown Manhattan
is one of the most important transit
corridors in New York City. A large
portion of its track in Queens is
elevated and has fallen into disrepair
due to MTA’s lack of funding. This
project proposes the establishment
of a Special Zoning District along
the train line, where unused FAR of
the vacant lots along the line can be
offered to developers as incentive for
dense affordable housing.

DUST CATCHER
Air-cleaning Porous Tower in A Dense Neighborhood
University of Hong Kong — Spring 2017
Undergraduate Design Studio IV
INSTRUCTOR
Ulrich Kirchhoff
PARTNER
Jason Liu
Inspired by the Ethics of Dust series by Jorge Otero-Pailos, this project tries
to engage with urban pollution and its manifestation as dusts on surfaces.
Dusts and small particulates, in this sense, are instruments of measuring the
air pollution of a specific area. A question comes up in the process of the
visualization exercises: What if we can build to take in pollution and purify the
air? Can architecture acts not only as a shelter for the people inside, but also a
sheltering device for the urbanites around it?
A high-rise tower with varying degree of porosity, both manifested as its facade
and its form, is envisioned as a filter to the densely populated district of Sham
Shui Po in Hong Kong. The envelope is not a singular level, but a combination
of three layers of concrete wall with different amount and sizes of holes as
air filters. These porous layers weave in and out to create spaces that have
different level of protection from the polluted air from the outside. In the mean
time, the multiple layers of rough textured walls trap the dust particulates of its
surroundings and clean the city’s air.

Dust Portfolios
Pollution across the district of Sham Shui Po is surveyed by examining the dust
accumulation on street signs. Dust is collected and documented using duct
tapes being stuck three times to the surface of the signs. These tapes are then
observed with both the naked eye and under the microscope in order to quantify
the density and size of particles of the dusts collected in a specific area. The
data is then used to visualize the severity of pollution in Sham Shui Po.

Experimental Prototypes
A series of prototypes are made to experiment with the formal qualities of
porosity as a concept to capture and filter dust particulates in air. In particular,
series of filters with varying pore size and density are tested to find out the type
of porosity that filters the most amount of dust particles. Magnified profiles of
the dust portfolios are also used to generate surfaces and tower prototypes that
is conceptually representative of the pollution in Sham Shui Po.

swells in the lower middle half with
increased porosity for more intense
filtering of air then it slowly tapers
off to the top. The air flow pattern is
represented as isolines on the plans.

Porosity as Protection
Spcaes of different programs are
distributed across the tower based
on their sensitivity to air pollution. The

This project reimagined a previous proposal devised by a separate classmate in
previous design studio in order to make it a feasible project with consideration of
site, code, and technology constrains. Retaining the original radial concept of the
building acting as a community center, the building organization is reconfigured
to build a clear formal language under the constraint of the building code. The
structural and mechanical system have also been considered and integrated in the
architectural layout. The building is designed beyond a conceptual argument but
seen as a combination of multiple working systems.
Facade details are also developed in this project to reflect the site context and the
design language of the building. An appropriation of the wood siding common to
the family houses in the surrounding area, a custom designed aluminum siding and
cornice system is designed to reflect the positioning of the building as a modern
institution in a largely residential New England neighborhood in New Haven.

Partial Renovation of Single-family Home in Syosset
Davies Toews Architecture - Summer 2022
Professional Work
CLIENT
Private
Ridge is a partial renovation project of an existing five-bedroom single-family home
in Syosset, NY. Half of the first and second floor is set to be renewed and refitted
to fit the current lifestyle of the owner. An outdoor porch area on the first floor is
proposed to be enclosed and fitted with a new bedroom that is accessible and
close to the main living space on the first floor. Additionally, changes are made to
the closet space and bathroom of the primary bedroom area to open up the space
and view of the Long Island Sound.
We were the main design and executive architect of this project and is responsible
for the survey of the existing condition of the house. A set of as-built drawings
were created together with the proposals made to the renovation. The set
illustrates part of the in-progress schematic design drawings of the renovation that
was presented to the client at the initial stage of design.

Sands China
An existing unoccupied service apartment building was completely renovated
as a new apart-hotel operated by Four Seasons in Cotai, Macau. The new
extension is an exclusive offering to the VIP guests of the resort with exquisitely
designed suites in contemporary luxury style. The scope of the project includes
the conversion of all apartments into hotel suites, the addition of two high roller
gaming areas, the renovation of all public areas, and the main entrance of the
hotel. The original architectural layout was altered to fit the interior design by
Peter Silling & Associates. Additionally, the back of house spaces were rebuilt to
fit the new program addition.
Leading a team of interior, landscape and engineering consultants, we were
responsible for the daily design and site coordination of the project. We also
worked closely with the client’s project management in meeting the needs of
both the owner and the hotel operator. Additionally, we also worked with the
local architect of record in preparing the statutory submission documents to the
government.

ESKYIU PLAYKITS challenges the definition of an exhibition by incorporating
community-engaging interactive elements to its core. Play, as an activity is seen
not just an act of recreation, but more so as a form of social interaction that
allows exchange and mixing of people from various backgrounds. With the aim
to achieve this, a question popped into our minds: How do we maximize the
potential of the limited black box space within a finite period of time?
The temporary exhibition is defined and redefined by a kit of transformable
objects that have the ability to be reconfigured into objects of different purposes.
Several training hurdles can be turned into a chair, and a chair can be turned into
an musical instrument. The flexibility enables the black box to be transformed
into a multipurpose space that was constantly reconfigured throughout the week
as a public community space for each and everyone of us. It is a space of sports,
but also one for dialogue, and even music performance. This exhibition tries
to subvert the conventional mindset in dividing the artifacts being seen on the
pedestal and the patrons appreciating them. The two sides are displaced into a
two-way relationship that involves the engagement of the participants with the
objects, and in turn they become part of the exhibition itself. It is a projective
retrospective interpretation of the way we build public space, and the way we
make it inclusive.
