TIMBER HILLS
a social justice center promoting sustainable building
Situated in an industrial zone of downtown Los Angeles, Timber Hills serves as a public amenity in its services provided while also championing sustainable construction through locally sourced timber in what is a relatively undeveloped part of the field in the United States.
1 | SHORTAGE OF GREEN SPACE
Around the site, there is a severe lack of green amenities, with limited park space leading to worse air quality, and a lack of gathering space for local residents.
2 | INDUSTRIAL ENVIRONMENT
North-East of the site, the zoning and current use is predominantly industrial despite being situated very closely with residential zoning. On the South-West, a 'publicfication' has begun a sprawl towards the industrial, where Timber Hills will become the newest addition of public facilities.
3 | STORMWATER DRAINAGE
The site sits at a arterial intersection with a vast network of drainage tunnels leading to it, making it a useful rain and water collection point to filter local rainwater.
4 | TRANSPORTATION NETWORK
A myriad of public transport networks converge towards the site of Timber Hills, making it a pedestrian friendly area that encourages walking and cycling. The building features no parking to encourage reaching it through more sustainable transportation systems.
Concept Sketch
1 | ORIGINS
Also referred to as Shiribasami-Tsugi, the Shippasami-Tsugi joint is an iteration of the Kanwa Tsugi. Due to it being a modern iteration, it is rare to find in practical construction.
2 | CHARACTERISTICS
The joint has a t-shaped tenon and mortise where the members are joined from the side. The tenon and mortise is not discernible while allowing the members to resist bending stress and tension.
3 | APPLICATION
For a contemporary mid-rise tower, the Timber Hills requires extension of its vertical structural members and the structural capabilities of bigcone douglas-fir suits the tenon and mortise connection.
SUSTAINABLE MATERIAL SOURCING
The project aims to reduce its embodied carbon footprint of its building materials through the use of locally sourced heavy timber. Bigcone Douglas Fir sourced from Southern California makes up the bulk of the wood used in Timber Hills, setting its structural framework for the other material expression to rely on.
CONCEPT
The primary driver of the building's form is the interconnectivity with the urban landscape, and the stepped down, sloped nature of the roof allows for a continuity of circulation through what is public and what is building.

HEADHOUSE EXTENSION
The headhouse becomes support system for the community, acting as a career and business incubator. The space extends into the main drill hall of the armory, assimilating more with the interior marketplace.
BRINGING IN THE STREETSIDE
The Expanded Marketplace is a celebration of the border conditions of the armory, where streetside activity such as street vendors, activists, and community businesses are drawn into the interior of the armory and the interior paths provide shortcuts between the surrounding communities.
BLENDING OF PROGRAM
Educational programs lean towards the north to serve the adjacent student population, and more active programs tend towards the east where the neighborhood edge is busier and noisier. Programs however, begin to share blended spaces through the interwoven 'marketplace'.

METROPOLITAN MODAL SPLITS
transportation breakdown for major urban hubs
Throughout the most populated and economically vibrant metropolises around the world, different cultures and how their urban fabrics formed determined different preferences for transportation. However, almost all cities had a large presence of personal vehicles, public transport, or a combination of the two. While certian cities were more walkable compared to others, infrastructural systems were always necessary to support populations so large.

UNI-MODAL CITY CATALOGUE published in digitalSTRUCTURES
Before conceptualizing a truly multi-modal city, iterations of mini city blocks were produced to conceptualize what cities would be like if planned around a single mode of transportation. This lateral form of experimentation plays with the architectural typology’s relationship with existing systems such as railways, roads, and ramps, resulting in eccentric examples such as cities planned for skateboards, escalators, or even spacecrafts.

LONELY LABORATORY
a method of redefining sites of ecological study in marine habitats
The lonely laboratory speculates a future of harmonious environmental study, redefining human-ecology relationships through a symbiotic laboratory that transforms itself to become the ecosystem. The island, despite being a product of the Anthropocene, is a site of observation for the lone human.

'REVERSE CEILING PLAN'
ISLAND TRANSFORMATION
Segments of rings act as the framework for new micro kelp forests. Coral polyps have attached to the aragonite crystals, forming a small reef on the underbelly of the island. Seagrass grows on the geofabric. Crabs, starfish, and other shallow water organisms crawl in the crevices of the undulating platforms. Fish, octopi, jellyfish, and other marine organisms wander throughout the shallow habitat.
DAY 1 DAY 2 DAY 3 DAY 4 DAY 5
ARAGONITE GROWTH SIMULATION
The substrate is formed with acids reacting to dolomite, a limestone that reacts to form aragonite, a crystalline form of calcium carbonate that also happens to be the corpses of coral, the main substrate new coral attach and grow on.
CELLULAR MATERIAL
The vessels for the fluids are composed of a clear polymer that absorbs water, transforming its refractive index to be identitcal to water. This allows for a perfectly clear surface that maximizes sunlight exposure to plants at lower strata.

URBAN CANYON
a regenerative renovation of an abandoned shophouse
Located in the heart of Ho Chi Minh City, the original Shophouse 48 houses a juice shop and 5 units that has been delapidated and abandoned.
Urban Canyon aims to introduce a new discrete entrance into the private residences and courtyard while maintaining an expansive doorway to the building's front bamboo array. The inner courtyard expands into a common space that invites natural light into what was a dark concrete shell.

The current hallway leads to a dark, enclosed stairway shaft with minimal natural light. The stairs that lead up to the higher units are narrow and steep, making traversing the building unpleasant and dangerous.

PERFORMATIVE LINING
The new proposed void becomes an open courtyard that appears slim in profile at the ground floor entrance, expanding to a larger courtyard that opens up to the sky, allowing more natural light to enter the residential units. An additional void is carved from the entrance for streetside visitors to get a glimpse into the shared artist's space as well as the veil system that lines the courtyard.

THE CURTAINS
optimizing facade design through data and parametrics
The Curtains is a tower designed with the intention of activating Broadway as a pedestrian channel, all whilst using data driven design practices to generate a facade that responds to a multivariate environment.
THE PROCESS
The project was as much of an exercise in BIM workflow as it was a design challenge. Climate studio and grasshopper tools such as ladybug and honeybee were used to analyze environmental conditions such as wind speed and direction, view analyses, solar illuminance and glare, and others.
1 | Broadway side site is set back for improved pedestrian flow and public engagement.
2 | Podium massing is tilted outwards to be parallel to street.
3 | Three extrusions come out of the podium with the two residential towers having greatest access to views.
4 | Podium cantilevers over entrance plaza for shade and increasing public space.
5 | Voids are introduced for additional outdoor space and amenities.
6 | Terraces and cantilevered decks are scattered for green space access to residents and office workers.

DAYLIGHT
| All three towers have plenty of daylighton the perimeter, and the only residential spaces that don't have enough are the cores and corridors.
VIEWS | The building's massing and orientation is optimized, with 73% of the building's floor area having quality views.
GLARE | There is overall quite a bit of glare on the south facing facade, and interior measures such will likely need to be taken in addition to the louvres.
ILLUMINANCE | There is significant illuminance throughout the living spaces as well as offices and meeting rooms, reducing interior lighting energy usage.

NEW ALEXANDRIA
reimagining libraries to be mazes of discovery
Existing libraries resist disorder, failing to subvert banality in their spatial offering to visitors. The book’s identity serves purely as Macguffin and the libraries’ circulatory space drives discovery, and the architecture itself becomes a maze in which visitors attempt to solve. New Alexandria reinterprets history’s symbol for record and scholarship through the lens of a modern world that has little need for the physical storage of information.
