Originally developed as a lumbermill in the mid 19th century grows to be the hub for ship building, coal, and timber in the mid 20th century and slowly declines its activity. Late 20th century revitalization efforts shaped SLU to the biotech hub that it is now.

Upon researching different strategies for a double skin facade, we found that ETFE, a form of plastic is a very versatile and reliable form of material. With less risk and cost , it out-performs glass in most cases.

Connect
Steam Plant Renovation and Addition
Downtown Pullman has been declining in popularity and demand post-pandemic due to poor commute from Campus, lack of enterntainment. Connect is an attempt to answer those concerns by renovating the historical steamplant and adding a new multi-use building which houses classrooms, restaurants, and offices for local business.
The ramps and stairs are installed to allow travelling building without entering the building.
Direct path from street above to improve building use as well as responding to harsh incline.
The two atriums are inspired by the chimnies that the original steam plant housed.
Steamplant Facade Preserved by installing a glass wall in front which can also be used as a lounge space.
Original Steam Plant Shoot is used as an elevator.

Rainier Valley Office
The Office in Seattle aims to improve user experience as well as building performance by creating an Outdoor area in the center of the office. The main focus of this project was to familiarize myself with energy efficient construction strategies as well as focusing on a tenant experience.
To improve ventilation, Rainier Valley office has an AtriumThat spans for almost 30’ x 15’. This is enough space to host semi-outdoor events for the office. Additionally, roof slope helps harvest daylight using a thin-film solar panel. The slope also improves daylight in the office duiring peak hours.

2400 Jackson St. Complex
CLT x Pre-Fab
By utilizing CLT and Prefabricated parts, Cost reduction and quick construction is possible. Prefabrication allows flexibilty in design and can help improve design if the budget allows.
2400 Jackson St. Complex aims to foster community by creating a green walk to connect the 3 towers.
The rooms will be assembled like building blocks. The main kit of parts are 12’ 6”, 25’,37’ 6” x 10’. Holes can be punched in areas with windows and a separate facade can be installed if budget allows.
Green Roof to decrease carbon footprint and resuse as urban gardening
8’ Corridor runs in the center of the apartment.
First floor is where local businesses and shops to improve community equity.
Simple CLT runnig track connects the three towers.

Oak St. Residence
Oak St. Residence is a single family house design exploration based in northern Washington, where snowfall is common. One of the main concept upon developing the Oak St. Residence is Public vs Private in a more predominantly private environment.
The main materal palette is an Oak finish on both the interior and exterior for more private spaces and a concrete finish for the public spaces. The Oak allows the private and semi-private space to feel cozy while the concrete helps the public space to feel cleaner.
The key to this project is the hallway. It is in the center of the project and it is what separates the public and privates spaces. The image above shows the hallway on the first floor. The hallway also acts as a portal to the outdoors as the main door is located as well as having a full view to the courtyard space next to the bedroom.
