“ HELLO,

my name is JOHAN CHEAH I am currently an Architecture and Architectural Engineering major at The University of Texas at Austin in the process of completing a six year dual degree plan. This portfolio features a selection of my work.

From a young age, I have always aspired to create. Fascination in the built world and the importance of architecture in society has led me to pursue everything there is to know about buildings, from design to construction.

URBAN ZIPPER Design 7 // Fall 2018 Professors: Igor Siddiqui, Gaelle Breton, Jean François Renaud Location: Paris, Frace Team: Solène Pasztor, Enoh Rusu, Antoine Troccaz, Natalie Avellar, Raymond Castro

Although roads are meant to create connections between two spaces, roads of the scale at the highway create divides on an urban level. Is there a way to reconnect two fractured sides at a pedestrian friendly scale? At our site is an existing structure, framed by the tramway, canal and a boulevard, however the Périphérique runs down the middle of it. The highway divides Pantin from Parc de la Villete, and in the turn, the rest of Paris.

To connect the two sides, an aggregation of public play and gathering spaces spill through the highway underside and carve into the ground, creating courts, sitting areas, and shops. A “zipper” of program is used to tie Pantin and Paris. The existing manufacturing building is transformed into a friendlier, public space for gathering, and production, featuring fabrication labs, exhibition space, coworking spaces, and a brewery. Housing towers with big windows for views and lighting are lifted up on stilts, bringing life into the area.

FLOATING CHAPEL Design 6 // Spring 2018 Professor: Johanna Reed Location: San Antonio, Texas

To reimagine what once was and to appreciate what currently is, the chapel “levitates� over the ruins of the original church of Mission Espada, San Antonio, one of the oldest pieces of Texas history. The building appears as a simple white mass floating in the air to be in harmony with the rest of the site.

The structure of the building is held up by steel columns that are masked by a mirrored glass on the exterior to give off this floating effect. Upon entering the chapel, visitors are greeted with a splash of diffused rainbow colored lighting that paint the interior space as ornamentation. The space is meant to give visitors a beautiful, calming space for worship that emulates the dimensions of the original church, but a contemporary reinterpretation. The building then extends with the rest of the existing complex to form courtyard and meditation spaces under the same architectural language.

UTOPIA 2018 EERI Seismic Design Competition Entrant Role: Design Lead Location: Los Angeles, California Team: Troy Marasigan (Captain), Jason Xu, Daniel Duffy, Maddey Collins, Autusa Behroozi, Albert Coleman, Devin Diep, Fabien Herrera, Grace Ito, Colleen Jones, Alexander Ko, Elton Nyugen, Nathan Ramirez Recognition: 6th in Proposal, 7th in Seismic Cost, 9th in Communication, 9th in Architecture (out of 40)

This project was an entrant for the 2018 Earthquake Engineering Research Institute (EERI) Undergraduate Seismic Design Competition, featuring 40 universities around the world. Towers are judged based on proposal, presentation, architecture, and seismic performance. A balsa wood model is tested with a shake table that simulates an earthquake. I was the lead designer of a small team that represented The University of Texas at Austin.

In order to take advantage of the breathtaking views of downtown Los Angeles, two corners of the structure are completely removed. To compensate for this bold move, the structure consists of shear walls and diagonal members which will brace and transfer lateral seismic loads in this earthquake prone area. In the spirit of a structural design competition, the structure itself is the architecture. The diagonal members form the web like facade, providing an eccentric addition to the Hollywood skyline.

ground motion 2 SAP 2000 model

Using a digital model in SAP 2000, a structural analysis program, we are able to create quantitative predictions of our building. The program is able to simulate seismic activity and calculate the resulting acceleration and displacement at each joint of the building.

The balsa model was constructed floor by floor with the assistance of laser cutting technology.

Assembly was by hand over the course of a five days.

GUELPH MARKET HALL Design 5 // Fall 2017 Professor: Michael Garrison Location: Guelph, Ontario

Located in a unique site, the form of the market hall is derived by a convergence of travel: train, car, and pedestrian. Two bars bend and merge to form a large cornucopia like space, seemingly spilling out food and life onto a main plaza. A green walkable roof introduces a new dynamic park space providing outdoor terraces, hills, and views. The roof also adheres to Guelph’s sustainability goals by incorporating systems that manage snow and water to be reused for plumbing systems but also heating and cooling through a radiant system. The design combined with its location allows the building to not just be a market hall, but the premier destination for Guelph’s economic and cultural life.

3100 GUAD APARTMENTS Design 4 // Spring 2017 Professor: Charles Di Piazza Location: Austin, Texas

The building consists of rotated living modules which have been angled to optimize daylighting and views. Located in the heritage neighborhood in Austin, TX, which consists mostly of single family units, the complex introduces increased density in the area while the tilt gives each unit more individuality, and a dynamic facade. The ground level consists of a courtyard with light wells that lead into the parking garage along with shared amenities, such as shopping, coworking space, as well as a pool and amphitheater space.

TRAVEL SKETCHES Notetaking is the process of jotting down words in order to remember ideas.

Similar to this, sketching is the notetaking of space. The process of drawing not only engraves your ideas and your perception into your mind, but also onto a physical medium that can be used as a tool for communication. These can range from quick scribbles to more sustained drawings. As an architecture student, it is essential to experience different spaces to influence design. Here I have shared a few sketches from travels in Europe and Asia.
