THE POROUS SPINE – DIFFERENTIALLY GROWN CLAY

CD4003

This project explores a modular pavilion system integrating terracotta cylindrical columns and lightweight PLA roof components. The design emphasizes spatial rhythm, modularity, and visual coherence, using a repeated unit composed of three columns and a triangular PLA roof module. These modules connect flexibly across the site, forming a dynamic yet structured layout. Occasionally, four-column intersections are introduced—not for structural support, but to enhance spatial continuity and shared moments. The overall configuration fosters a porous and flowing experience, guided by principles of differential growth, where each element and connection contributes meaningfully to the expressive and systemic logic of the pavilion.

Clay 3D printing is an emerging fabrication technique that merges traditional ceramic materiality with digital precision and customization. This process involves the use of paste extrusion, where a viscous clay mixture is extruded layer by layer through a nozzle, controlled by a robotic arm or gantry-based 3D printer. The workflow begins with digital modeling, often using parametric tools that allow designers to experiment with complex geometries, perforations, and textures that would be difficult or impossible to achieve by hand. The material behavior of clay plays a crucial role in the printing process. Its plasticity and shrinkage during drying and firing must be carefully considered in both the design and print settings. Parameters such as extrusion speed, layer height, and nozzle diameter are finetuned to accommodate the specific clay body used. Supports are generally not needed, allowing for intricate and efficient builds. This process expands the boundaries of archi

The principles of assembly and disassembly are central to the development of adaptable, responsive, and sustainable architecture. In the context of pavilion design, these concepts support structures that are not only modular and efficient but also capable of transformation over time. Assembly involves the strategic joining of individual components to create larger systems, emphasizing ease of construction, structural logic, and material efficiency. Disassembly, on the other hand, considers reversibility—allowing parts to be taken apart, reconfigured, or relocated without damage or waste. This design approach aligns with the ideas of temporary occupation, mobility, and seasonal adaptability, especially in contexts where permanence is neither required nor desired. The sketches and models presented here explore various aspects of this logic: from foldability and compactness to expansion and structural reconfiguration. Techniques such as origami-inspired folding, modular tilin

This project explores the form development of a column made from terracotta, designed specifically for passive evaporative cooling through increased surface area. Drawing inspiration from the natural principle of differential growth—commonly observed in biological systems such as plant leaves and coral structures—the column evolves into a complex, porous form that enhances air flow and water retention, thereby optimizing the evaporative cooling effect. Terracotta, a breathable and porous material, is particularly suited for this application due to its hygroscopic properties and thermal inertia. In addition to the column, a complementary roof structure was integrated into the pavilion design. Fabricated using PLA (polylactic acid), a biodegradable thermoplastic, the roof also adopts a differential growthbased approach. The resulting organic and fluid geometry provides strategic shading, encourages air circulation, and reduces thermal gain. While the column actively cools th

Finalized Module

This pavilion system is conceived as a modular, site-responsive structure that combines spatial performance with environmental intelligence. Its design is based on a network of repeating units formed by terracotta columns and lightweight PLA roof modules, arranged with careful attention to rhythm, porosity, and aggregation. Each module is composed of three columns and a patterned canopy that together create a fluid, flexible system capable of adapting to site contours and user movement. The modular logic enables easy expansion, contraction, and reconfiguration across various contexts. Strategic openings and overlaps generate transitional zones between inside and outside, fostering dynamic spatial experiences. The system’s responsiveness is enhanced by its passive cooling strategy: warm air is drawn through custom-formed terracotta columns equipped with internal drip irrigation. As water flows over the porous surface, evaporative cooling is triggered, lowering air temperatu
