Confluence: San Francisco Mission Creek Community Center Fall 2013 Instructor: Rene Davids
Mission Bay is undergoing major urban transformations from a warehouse district to a high-end residential area. Besides housing construction it also requires new infrastructure which will connect the new district with the rest of the city. The given site and the adjacent creek appear to be a natural barrier, which splits the Mission Bay in two halves and separates it from the city; therefore, there is potential to reunite the neighborhood by bringing the infrastructure to the site and fix the missing links of the urban fabric.

To overcome the flatness of the site and explore various possibilities of lansdcape manupulation a series of plaster models were done using fabric molds as the media for flexibility and plasticity. Yearly wind and tide variations affected landscape design, enabling its interaction with infrastucture. Tall grasses, planted along the paths, interact with the strong wind currents and smooth down walkways. During high tides the paths, which are located closer to creek, disappear letting the water to penetrate the landscape. To overcome the isolation of the Mission Bay South, two bridges across the Creek were proposed. They extended the busiest 5th and 6th streets enliving the new district.

In the original analysis streets of the neighboring districts were extended and connected on the site. The resulted intersections were then treated as centers for the major programmatic blocks, which then were transformed into several public squares, community garden, auditorium, and a basketball court. The site was treated as a miniature of the city with the architecture being a mini master plan. The primary circulation is assigned to the long strips of elevated pathways, which go up and down, leading people both along the buildings and through them. In fact the buildings are becoming part of the infrastructure. The crossing paths were directly taken from the existing streets, making the program clusters accessible from different points along the site.

Soft Systems Performance Pavilion Spring 2014 Instructor: Lisa Iwamoto Inflatable structures are characterized by great flexibility and adaptability. They have a possibility to replace rigid building materials and set up a new era of architecture, which is ‘lighter than air’. A performance pavilion design addresses the nature of pneumatics and their physical qualities. The weather-tight condition was met by pressing inflatable tubes against each other. The equal air pressure inside the tubes results in a flat wall condition at the area of their interaction. Larger “structural” pneumatic tubes are fixed at the bottom appearing as a straight line on the floor. The top part is semi-fixed by the intricate mesh, which also holds small inflatable tubes and creates a canopy. The area between the larger inflatables was treated by a packing algorithm, calculating position and size of the “fill” cushions. The whole structure is collapsible, once not in use and adaptable to the terrain conditions.

The system was born as a hybrid of two precedents, accordion and a bridge designed by Thomas Heatherwick. Organized in a strip, pneus naturally are curiling into a circle. This observation gave a form to the pavilion, which corresponds both material and system behavior.

Designing a pneumatic system, one has an opportunity to introduce thick poche volumes. These ‘solids’ of air fill up the areas between the main program elements, such as auditorium, circulation area, lobbies, and entrances. Moreover, they function structurally.

Good Food Spring 2013 Instructor: Michelle Chang The building is a conjuction of multiple and varied programs centered around a common set of interests, which could generally be described as food awareness and education, challenging the norms of mass food production, advancing food research, slow food, promoting and supporting urban farming and food production, and more general celebration of good, healthy, local food. All programs that comprise Good Food (food hall, exhibition space, research institute, food bank, cafe, kitchens) exist within the Bay Area, but do not currently coexist on one site, or within one institutional construct. Therefore, the project is a unique opportunity to integrate sustainable design practices with sustainable food habits.

Octet Truss + Playhouse Fall 2013 Instructor: Gary Black with Faisal Aboud Goals: - the structure should perform more than one thing; i.e. be aesthetically attractive as well as structurally stable - attractive to kids, explorative - assembling the playhouse should be relatively easy
Rhino | SAP2000 | V-Ray | Photoshop | Illustrator
Playhouse 1 of 3
The playhouse was inspired by a children snake puzzle which can be twisted in many various combinations to create dozens different shapes. Exploring the concept we envisioned each section of the snake being an occupable unit, which joined with other members can be both a path and a node. Continuing in a spiral all the way to the top triangular units direct the playhouse exploration. Each triangle will initiate different activities, like crawling, hanging on the bars, sliding, climbing, hiding, etc. Since the shape of the toy resembles the truss structure we researched on the type of the trusses, trying to find the balance between the necessary visual qualities as well as structural performance. As a result, we chose an octet truss, which is widely used for structural frames and, as in our case, could be occupiable. Octet truss fits perfectly into the design concept, since it breaks up the space into pyramids, which can be assembled together creating a building as well as a route through it. It also has impres- sive structural performance since bending moments are transmitted as tension and compression loads along the length of each member.
