FUTURE FOUNDRY ARCH 411 INSTRUCTOR: CHANDLER AHRENS PARTNER: ANGE LONG

As AI becomes more and more developed, the world begins to move towards automation, which sees humans taking more and more of a backseat. For this project, we designed a speculative factory in the year 2054, when AI was speculated by Ray Kurzweil to overtake humanity.

We have hence designed a factory that is beyond human scale, harvesting solar energy for a steel mill that leaves out the human element, reducing the manufacturing process to spectacle for a humanity that is no longer in touch with manufacturing without the aid of computers.

This factory utilizes the power of the sun, caught with an AI powered central sun-catcher, to power a blast furnace which is used to further produce sun-catchers of many different scales, then ships them out across the country as an alternative energy source.

STUDY MODEL To begin the design process, we set out to create a model in which we could study different moments and material usages. In order to do so, we first started by creating a digital rhino surface, which we then ran a grasshopper script on. This script enabled us to subtract the geometries of our solar-catcher to generate spaces that were beyond our control- which we then fabricated in a physical model (shown right) in order to isolate specific moments that we could thus utilise in our final factory plans.

The process of making this model involved a decent amount of switching between physical tests and digital design, enabling us to see the project from both fronts and aiding in a design that could both be more adventurous whilst also physically feasible.

ARTIST RESIDENCY ARCH 311 INSTRUCTOR: KELLEY VAN DYCK MURPHY

ST. Louis’ Grand Central Arts District is home to many arts venues- the Pulitzer, Fox Theater, The Symphony Orchestra, Contemporary Arts Museum, and the Kranzberg Art Center are just a few which dot the neighborhood. In the spirit of this community, this studio aimed to design an artist residency within the GCAD. project, The project emphasized a design proportionate to the nearby surroundings, but with an envelope that both provided shading of potentially sensitive pieces, but could equally be open to allow light into studio and living spaces, and an artistic flair to denote the creative nature of the building.

ENVELOPE STUDIES To begin the design process, a physical model was cast out of concrete, which enabled the project to begin to play with a non-normal and more gestural vernacular. In order to fully take advantage of the liquid nature of concrete, I designed a set of curved molds in which the concrete could be poured.

The envelope was developed by casting a variety of concrete blocks with different shapes, which then formed the basis for a series of wall and envelope studies which borrowed a formal language from the previously made concrete blocks.

This formal language would also begin to form the first iterations of the artist residency, and although the shape is not a one-for-one extrusion of the block models, the form of the residency borrows shapes from these blocks.

RESILIENT RESIDENCY ARCH 312 PROFESSOR: PABLO MOYANO

Set in an unspecified location in the lower Mississippi’s Tornado Valley, the question of this studio was to design a concrete focused dwelling which would reduce the impact of a natural disaster contacting with the house. Designing structural and protective overlaps, a lack of purely flat surfaces, and minimizing window surface area were ways to create a house that would help stave off the worst of a potential tornado.

The project utilized Ultra-High Performance Concrete, a particular mixture designed for strength and durability, and the sequential casting method developed by Pablo Moyano. These techniques were first explored in a 1’:1/16” scale physical model, cast with actual concrete, and tested outside for a couple of days to form the basis for a feasible full-scale design.

ENCLOSURE STUDIES To begin the design process, a series of envelope studies were made which explored defensive walls.

The reduction of purely flat surfaces was heavily emphasized in my earlier designs, exploring a sense of folded walls and corners to stabilize the wall against flying debris.

The ideas learned from this stage of study models later became the quarter domes of the concrete model (next spread) which was structurally reinforced by piano wire. This wire provided the tension that was required to offset the compression of the concrete. By using actual concrete, albeit at a smaller scale, the project could be grounded more in reality, with concrete’s limitations being tested and pushed in the study model.

Above: The process of casting the wall. The molds were 3D printed, and held together using clamps. As each layer was cast, the molds were moved up another layer to complete the dome.

Above: The enclosure study’s final form. These were freestanding wedges of Ultra High Performance Concrete, measuring almost a foot high.

TREEHOUSE CONTEST WORK PARTNER: AUSTIN TSAILIN Done for a competition with volume zero, we aimed to capture the whimsy and childlike wonder of treehouses from our pasts. The residents in mind were two artists, and we wished to forge a connection with the nature around the house. Set near Strawberry Lake in Oregon, we designed the project out of local Douglas Fir and sought to forge different views of the neighboring mountains a a way to inspire the residents, and built the building on a mightly Douglas Fir sitting on the shoreline. Programmatically, the treehouse was designed to serve as a natural residency for two artists.

Formally, it was built to wrap around the Fir tree, forming a wooden knot of sorts, and putting the tree front and center in the house.

MATSUMOTO MODERN EXHIBITION WORK ARCH 333A INSTRUCTOR: KELLEY MURPHY

George Matsumoto was a Japanese American designer during the 40s and 50s, when Japanese Americans were being sent to internment camps.

Briefly studying at Washington University in St. Louis, we were tasked with representing some of the work he did and analyzing the influences that Japanese Americans had on modernism.

This house in particular was the Women’s Day Douglas Fir Pine Association Vacation Home, which was sold to the public in magazines around the US for cheap. The house was designed as a kit of parts, being able to be assembled with minimal woodworking skill and talent. Ironically, many of these vacation homes were built in places where Japanese Americans could not move in to, and the magazine portrayed families of white Americans moving in to a house with an “oriental flair” This presentation sought to pay respects towards the influence that Matsumoto and many other Japanese American designers had towards the Modernism Movement, with both newly made drawings and a model built according to the plans that Matsumoto had published in Women’s Day, with near proportional sticks and almost all cut and fit jointsmeaning that many of the pieces did not require gluing.

Above: A perspective plan done for the project. Note the Tatami Mat-like grid organization, a feature common in traditional Japanese housing, which Matsumoto used in his drawings frequently.

Right: Plan view of the Physical model, with the roof removed for a better look at the roof framing.

Above: Axonometric view, I attempted to present the mass produce-ability of the house and the pilotis (a staple of modernism that allowed the house to be built on any site) with a nod to the Ukiyo-E prints (floating city) of traditional japanese art, which themselves were siteless.

Above: The physical model, axonometric view. The site for this model in particular was inspired by a built example of the house in North Carolina, where a majority of Matsumoto’s projects were sited and built.
