Throughout Design Fundamentals 1, we were tasked with identifying conceptual structures within Rapson Hall on the University of Minnesota campus. We studied these conceptual structures through tracings, Rhino drawings and models, and physical models. This portfolio showcases some of my work from this semester.

Tracing the floor plans of Rapson is the first way we studied conceptual structures. These tracings identify some of the simpler conceptual structures that can be seen in Rapson Hall such as line, point, shape, volume, symmetry, and repetition.



These tracings highlight volume, angle, symmetry, repetition, balance, and divisions in space.



To study circulation, I chose a path to study that went from the basement to the first floor and out the door. I walked this path and took a picture every eight steps. To study the circulation further, I did a tracing of the Rapson floor plans, made a Rhino drawing of the path, and eventually made a three dimensional Rhino model showing the path. This led me to look into the implied volumes of Rapson, as well as the lighting in the basement.



Implied volumes Boundaries between spaces that feel separated from the whole are highlighted in red.



One thing that I noticed when studying circulation was the differences in brightness and types of light in the basement of Rapson Hall. Windows let in large amounts of natural light into some parts of the basement, while other parts are almost completely artificially lit. I wanted to try to show this in a 3D Rhino model.



When tasked with designing an addition to Rapson Hall, I didn’t want to change what was already there and I wanted the addition to have a similar feel to the existing building. To do this, I decided to add two additional floors to Rapson under the current basement. The courtyard from the original part of Rapson is extended downward into the addition, and beneath the newer part of Rapson Hall, each floor steps out more than the previous floor. The walls of the addition under the newer part of Rapson are mostly made up of windows and the ground is removed around them to let natural light in. The courtyard is extended into these new floors to tie the addition back to the original building. I also added skyways and catwalks to the second floor to increase circulation.

From this comparison you can more easily see the similarities and differences between existing Rapson and my proposed addition.

Precedent study

In this precedent study, I found horizontal and vertical elements, as well as volumes in a precedent building and my addition to Rapson Hall and compared them. I found that although the shapes of the buildings were different, many of the elements in both buildings had similarities. I used these diagrams to come up with some ideas for my physical models.

Physical Models Section

Both of these models are of the same section of Rapson Hall including my addition, but because they are made out of different materials, they convey different things.





This model shows the circulation paths on each floor. The wires that connect the floors represent staircases that connect the circulation paths.
