Forming Architectural Experience

1. Amplify Natural Sound

To take the sounds of the space and increase their wavelengths, in turn increasing the volume of the sounds

2. Stop Transmission

To prevent the passing of soundwaves from one space to another, with a physical intervention

3. Quiet Generation

Space only allows for generation of very soft sounds, overall a quiet space

Forming Architectural Experience

1. Stop Echoes

Remove the possibility for any echo to form in a space

2. Resonate

Allow for echoes to become louder and stay for a long time even after the initial sound was made

3. Spread

Distribute the passing of sound to various locations, but each location is speci ed

Forming Architectural Experience

1. Musical Generation

Space/objects allow for the creation of sound with a degree of control by the user, essentially musical instruments

2. Prevent Transmission

To prevent the passing of soundwaves from one space to another, with a physical intervention

generation: Pittsburgh Symphony is focused on the study of sound and beginning a conversation of what it means to flip the hierarchy of sensual perception of architecture, placing sonic perception before the visual. Through the strategy of clustering, the flow chart maps space and sound, using density as a binding gradient begins the conversation of what it means to create space around sound. Spread over three sites, each of these proposals are tied together through their approach to sound.

early site mapping

mapping: The above site mappings are a beginning into the exploration of what it means to cluster. The top set examines clustering built forms, drawing imaginary spatial boundaries around these clusters. The second row begins to look at what it means to cluster natural terrain conditions of a site. Both of these exercises were intended to inform an understanding of what clustering means.

clustering: The three sites (Washington’s Landing, North Shore, Station Square) were all studied through the lens of identifying the sound generating clusters on each site. In addition to that, the nearby population density was also mapped. The most important part of this mapping exercise was to draw out the site sounds, noted by the red forms that are in each cluster.

generative site mapping

form: After mapping each of the site sounds in plan, those forms were extruded to created three dimensional forms that were intended to be formal interpretations of the sound. These forms were then clustered based on the qualities of the sound that they offered. The organization of the forms responds to both site conditions, as well as programmatic needs of the site. Each site is focused around a mixed-use housing proposal.

site: The Friesenhahn Cave in San Antonion is home to some of the most important artifacts from the pleistocene era, or the last Ice Age. While the cave entrance is small, the possibility of other undiscovered cavities results in a large, invisible boundary, within which there can be no heavy site elements. In response, the massing of the various program elements are based around defining and responding to the boundary condition. Through radiating sections, each portion of the site dedicated to either program elements or circulation. All of these are joined by a series of undulating roofs that respond to the presence of massing elements. A consistent series of trusses holds these roofs up, further unifying the language of the site.

Tranquil Rim

program: The program for this site is a research centre, but one that is focused on the work of the archaeologists rather than the public. The organization of the buildings under the roofs is based on proximity to both the site approach and the cave itself. The welcome centre, library, and classroom are the more shared spaces of the site and sit closer to the approach of the site. The field house and lab are located in areas with more direct access to the cave, but also farther away from the entrance. The archive space sits between these two, acting as an intermediary space. All of these spaces are hugged by two large circulation spaces to and from the cave.

serenity garden spring 2022, fundamentals of computational design

in collaboration with Andrea Wan

panelization

: The Serenity Garden is a meditation and relaxation space that aims to create spaces that are private but still open to the natural elements. An important element of this design was the response to light. Based on an incident radiation study on the initial base geometry, the form was panelized in response to the average amount of daylight received over the course of a year. The glass panels are colored according to the amount of radiation received as well, responding to the actual light conditions in the structure.

connection: The space frame connections are a variation of a ball and pin connection, where both the pipe and the ball have a connection plate that extends out. A simple pin and washer system holds these members together. These joints come together in frames of three to hold the glass panels that make up the shell.

vertical longhouse fall 2022, impact competition

in collaboration with Brody Ploeger, David Warfel

design: Located in the city of Vancouver, Canada, the Vertical Longhouse is a skyscraper that is a reflection of the city’s long standing relationship with both the landscape and its peoples. The building is composed of three towers, each with an individual core with twisting slabs towards each other. The alignment of the slabs is intended to mimic the stacking of traditional inukshuk, an indigenous land marker used by the Inuit peoples of Canada. The tower is intended to act as a landmarking tower for the city of Vancouver, which has long lacked a single identifying building. The Vertical Longhouse is primarily residential, with mixed use at the bottom and shared office space in the connecting moments between each tower.
