CycleGAN was used as a tool to generate a speculative urban intervention. A possible solution for a city in dire need of green areas. The first step was to create a Data set of imagery to Train the GAN. The first dataset was produced from a high-quality satellite image of the selected urban area. The image was trimmed and divide using a Processing script. The second dataset was generated from a microscopic image of Chloroplas as the reference for a greener more fluid city configuration. + 550 - 650 kg/ year650 - 750 kg/year750 - 850 kg/year Organism in the city/ Barcelona Organism in the city / Barcelona

The highest pollution touristic spots in Barcelona were mapped using GIS software to analyze AIRBNB’s public record data. A spot in the middle of the old town stood out with one of the highest waste rates. The area is also a transportation hub for the city since there is both a subway station and a bus station connecting to the rest of the metropolis. What could be done to turn waste into an asset for the city?
Garbage produced per year.
Satellite Image. Reference data set A. Reference data set B.
The highest values were selected to generate. The points were then used to create a surface, that would then be turned into a relaxed mesh using Kangaroo. MesoInput scale. Output
The datasets are fed into the GAN to be analyzed by the algorithm. Once trained the algorithm will start a series of iterations that results in a new image that blends both inputs. The resulting image opens the possibility for a new, more organic, urban configuration. How to design an intervention that grows and adapts to the changing circustances of the city?
The computational design was used to generate a shape and a structure that responds to the specific physical conditions of the site.
First, a Python script was written to visualize the sun hours percentage for the chosen site. Once the final canopy was generated, the area was analyzed again to confirm the decrease in solar radiation.

Wolff’s law explains that every change in the form and functions of bones is followed by certain definite changes in their structure.
Structural Analysis
A structural analysis using Millipede showed the bending moment in the mesh, carrying its own weight. Understanding the structure as a dynamic system, Wolff’s Law was an inspiration to create a reactive structural system that would adapt to the forces generated on the surface.
Due to processing power limitations, a small area of the structure was selected as a test for the generation of the structure. The areas with a larger bending moment are highlighted in the red. The data from this analysis was collected and fed into a C# script. Components defining different behaviours for autonomous agents were created using C#. The environment of the agents was the selected mesh. There were three behaviours given to the agents. minimum separation, atraction to the stress areas and voronoi cell interconectivity. The agents are distributed in response to the stresses gathered from Millipede. At the end of the simulation, a pattern that represents the most efficient structure is achieved, Organism in the city/ Barcelona Organism in the city / Barcelona
A bacterial membrane can decompose the organic waste from the city and create a mesh that reacts to the changing conditions of the site. This membrane is then placed on top of the structural skeleton.
The final structure is a living organism that feeds from the outputs of the city, creating a metabolic system that grows and adapts to its surroundings. Taking inspiration from nature for an efficient solution and using climatic conditions as parameters for form finding. With slight variations, this type of intervention could help to create more livable cities in various contexts. Giving a local touch to innovative technologies.
The prototype structure was constructed using resin 3d printing with biodegradable composites and kombucha bacterial fermentation as the chemical process to produce the membrane.

A 3d printed structure can then be printed following the pattern and using recycled plastic gathered from the public system as the main additive material.

Starting from the smallest scale with which the human body can interact. We are investigating triply periodic minimal surfaces and the potential of these structures on a larger scale. The designs are modeled in 3D and adapted with the mathematical equations of the minimum surfaces. The model is then cut and ready to be printed. Using a resin 3D printer, the parts are produced with soybean oilbased resin. Dip parts in alcohol, UV Thecure.process is then completed with the addition of a handcrafted item made from locally sourced natural materials. In this case, sap from the pine trees in the area. The sap is collected, cleaned and placed by hand on each of the pieces. prototype

Using microfusion methods, a negative plaster mold is created that is suitable for receiving molten metal. .930 Sterling silver is used to fill the mold. Then it is cleaned, polished and sanded impurities by hand to reach the final product.
The final micro fusion process keeps the fidelity of the original prototype, thus maintaining the complexity of the geometry and even the pattern generated during the 3d printing process. This type of production opens up the possibility of a cheaper and faster workflow to create complex geometries in metal from a standard 3d printed model.
