From the initial stages of our international housing studio, located in San Juan, Puerto Rico, it became evident that the city’s climate would become a defining factor in our studio’s housing design. San Juan, Puerto Rico is located in a tropical climate, where the temperature remains constant throughout the year, allowing the definition of conventional thermal and spatial boundaries to be blurred. Throughout the design process, I focused on creating a series of spatial relationships that accept and pull the inhabitant through each of the building’s thresholds, while connecting these spaces to the outdoors. This defining spatial sequence is exemplified at the unit entry. By extending the living and dining spaces of each unit within the building to the outdoors, the living spaces are transformed into one large balcony space. While the connection to the outdoors is important in terms of giving the user the sense of being outside, additional important climatic elements were considered such as cross ventilation, solar shading, and protection from the rain. By creating a facade comprised of louvers that span across to the exterior corners of the living spaces, the resident can control and adjust the louvers to provide maximum thermal comfort and preferred lighting conditions.

The city of Valparaiso is a dynamic city, largely characterized by its geographical location. Located on the Pacific Coast of Chile, the city is encompassed by dynamic topographical features; the ocean to the north, and steep hills to the east, west and south. As a result of extreme changes in elevation, a spatial segregation is created between the lower plain (El Plan), and the 42 surrounding hills. This spatial segregation makes it extremely difficult for efficient pedestrian travel, inhibiting vertical connections and circulation for the people in the plan and hills. Moreover, a correlation can be drawn between the lack of program that is scarcely distributed into the hills due to the extreme topography. Currently 95% of the major program is located within the plan, which only directly services 5% of the city’s residents. Beginning in 1883 the city of Valparaiso began to construct a series of elevators that would serve as the primary mode of vertical circulation. Unfortunately, due to natural disasters and poor maintenance, the conditions of the elevators began to decline. What was once a series of 30 elevators, today only 4 remain in use. In response to the former and now dilapidated vertical transportation system, I have proposed to place a recreational facility on the former site of asensor Las Caùas. This 12 story facility will function as a means of vertical circulation, bridging the spatial divide between El Plan and the Hills, while also providing the community with interior and exterior recreational spaces. This 12 story facility houses a series of sporting fields and courts, exercise equipment, and meeting/gathering spaces, all of which is organized in a module of 3 levels.

One of the most iconic structures on the University of Minnesota-Twin Cities Camus is the Washington Avenue Bridge. Spanning a quarter mile over the Mississippi River, the redesign of the bridge not only connects the East and West Bank of the university, but it also provides the opportunity to connect its users to the often overlooked natural landscape of the Mississippi River Bluffs. Through a dual route system, pedestrians will have the opportunity to directly cross the bridge or meander their way to the other side, making use of the pavilions and exterior cantilevers that connect the pedestrians to the natural landscape. Three pavilions spaced out at intervals along the bridge interject into the central pedestrian corridor, encouraging users to enter into the pavilion spaces. These pavilions are programmed as a study space, coffee shop, and an information center, all of which offer ideal views bringing the public’s attention of the surrounding natural context. Furthermore, the central pedestrian corridor accommodates for the large pedestrian traffic flow that takes place on a daily basis, while the pavilions offer a way to reconnect to the surrounding context of the Mississippi River.

The intent of the Maggie Cancer Caring Center was to find and establish a place of healing for those with cancer, whilst adapting the programmatic issues of the center to the Mediterranean climate of Barcelona. Through the study of visual and physical connections in the form of an open and fluid space, I found a direct relationship between establishing a sense of community within the center and balancing it with the connection to its surrounding urban context. Located in a very open and public setting, the Barcelona Maggie Center incorporates an exterior shade and visual screen wall, which creates an even balance of privacy and connection to the surrounding context. The connection between interior spaces are enhanced through a series of visually and physically permeable glass walls. The visual and physical connections help influence and establish a sense of community for the users of the Barcelona Maggie Center, emphasizing the interaction between the interior and exterior spaces. The fluidity of visual and physical movement from the interior to the exterior spaces are further facilitated through large glass sliding doors located on the exterior/perimeter wall of the building.

Constructed Perspective: This value drawing was used to analyze the light and spatial qualities of the Nelson Atkins Museum in Kansas City, Missouri. By using white colored pencil on black paper, I chose to emphasize the contrast between light and dark, and how the curved ceiling conditions directed the flow and distribution of light down the surface of the curved forms.
