Space travel has long occupied the public unconscious.

Spaceships and space stations have a unique identity, needing to look a certain way in order for their purpose to be recognized.

This theory is not to be ignored, but embraced. The slick interiors and control panels are something tourists would want to see in a hotel room on the moon.

Architectural theorists have always been intrigued by how to curate a specific experience.

Coop Himmelblau and HausRucker-Co specifically set out to create spaces that could be set up and taken down in a matter of minutes, testing the limits of pop-up construction. Both groups theorized that architecture isn’t the shell, it’s the space within.

Designing a structure to be built in space requires not only the design of a structure to fit the public’s aesthetic expectations but also the feasibility of construction. It must be able to be put together with the least amount of construction equipment possible.

Antarctic research stations were studied to be not only precedents for scientific research in extreme environments, but also as successful closed loop systems that deter cabin fever. Spain’s antarctic research station, Juan Carlos 1 was described as being “a station where light and space are crafted around human activity” by architect Hugh Broughton.

Star Trek The Next Generation - Engineering

The Nakagin capsule tower was designed at the height of the metabolist movement. Individual capsules could be added, moved, or removed. This modularity greatly influenced the design of the moon base project.

Each capsule of the Nakagin tower was designed with extreme efficiency in mind. Desks, beds, utilities, and cabinets are all designed to be used interchangeably, allowing for a minimal room footprint.

Forced interaction with green spaces throughout the building section improves the mental health of the researchers living far from home. The gardens are filled with tower gardens, making the most use of the footprint they are given.

Each garden system uses 10% of the land required for traditional farmland. These vertical gardens would provide all of the oxygen and food required by the station.

The joy of micro gravity allows for the researchers and tourists alike to play. Playing makes us human, and being on the moon shouldn’t change that. It keeps the users healthy in both body and mind. The top floor is an observatory, accessible to tourist and researcher alike. At the other end, the bottom floor hosts the tourist spaces that play up the novelty of space tourism. They are constantly reminding the tourists of the danger and thrill that space travel brings.

Researcher bedrooms are more spacious, allowing them to be more comfortable in the station they now call home. The base is primarily designed for the researcher’s. The research conducted here will be of extreme importance and their mental and physical wellness

Tourist bedrooms are designed to be as cutting edge as possible and play into the fantastical aspect of space travel. They are taking aspects from science fiction novels, movies, shows, etc.

Fractalization drove the development of the architectural autonomous form. It starts with a diagram depicting the phenomena of radial acceleration. The further one gets from the center of rotation, the less acceleration is felt; given that the velocity is constant. The radius of the points are determined by what the radial acceleration would be at that distance from the center and the points are connected, giving the concept form.

The form is then added unto itself, forming a sort of triangular footprint. This form is paired with the Sierpinski Triangle, a fractal defined by an equilateral triangle. This allows the form to be repeated in as many iterations while still retaining the original outline.

The design build studio had to adapt to an oncoming pandemic and our designs autonomous forms were then derived from paper. The panels require a substructure for support. The original solution was to create beams in the shape of the autonomous form. This works so long as the pentagonal shape won’t be repeated. The structure is then developed into a repeatable system.

The paper form with structure, formed into an icosohedron

The panel design comes from the autonomous form. It lends itself to a positive and a negative expression. The two forms, along with a neutral solid panel are used to express interior functions on the exterior.

The primary framing consists of cambered beams connected to columns. Beams are connected by welded plate to bolted web connection. The beams themselves are cambered with the bottom flanges having a greater curve.

This is to provide more depth at the connections, where the shear will be greatest.

The site plan is laid out to mimic the plan of the gold dome.

The parking lot and most of the walkable site is paved with permeable pavers to help with drainage, mitigate the heat island effect, and also recharge the water table. The play area is flanked by trees and foliage to protect children from sound pollution and unwanted attention from the busy streets. The overlap between circles results in material change to further emphasize the circular concept.

FIRE STATION Fire station for Soweto, South Africa

As the fire station would be built in South Africa, availability and constructibility were key factors.

The soil on site is a gorgeous clay, providing both color and the necessary cohesive properties.

Rammed earth could be stabilized with cement and rebar, able to be used as load bearing and shear walls. This allow the rammed earth to be not only an aesthetic choice, but a structural one.

Using the soil from the site to become the walls allowed an energy offset from the typical site preparation. Despite using similar materials as concrete, the embodied carbon is much lower.

Locally sourced timber was found in one company near the site, GS Timbers. They offered different species of eucalyptus timbers.

The species of choice became Eucalyptus Cloeziana

E. Cloeziana has unique structural properties as a hardwood. It displays properties of a D50 wood, not in use with the timber code used in the States.

The species of eucalyptus grows twice as fast as Douglas fir, a species typically used in timber construction. It also sequesters twice the amount of carbon as fir.

The program was laid out in two angled groups. To support this while also assuring the grids would line up, they were placed according to 3-4-5 and 5-6-13 right triangles.

Supporting 5 different roof heights created the challenge of distributing seismic forces within the 5 zones. Curved roofs similarly required wind uplift to be checked among 3 different zones on each different roof. Using RISA, a bay model was structured for gravity loads to test the preliminary structural calculations. RISA does not support curved diaphragms, so dummy members had to be used.

The wall section to the left shows the roof sandwich, a corrugated metal panel attached to a vapor barrier, then connected to OSB panels. This system is supported by eucalyptus purlins, and finally connected to a timber truss. The connection between the timber truss and the rammed earth bearing wall is detailed above.

A steel saddle is bolted into a concrete bond beam atop the rammed earth wall. The truss is then bolted to the saddle.

Daylighting is a key driver in the design of the fire station, and as such, a bay model was built to test in the daylighting lab. The results are given in lumens, showing a distribution of daylight throughout the depth of the space. Overlaying that data onto the space creates a visual representation of that lighting. Rammed Earth window details were provided by SIREWALL and adapted to the project.

The first course of rammed earth is bolted to a continuous footing.

As the rammed earth is stabilized with cement, it does not require any extra care where it touches the earth.
