Introduction Tectonic systems & prototyping in architecture Prototypes allow designers to investigate design ideas and explore the structural performance and aesthetic possibilities of materials and construction techniques. The following is a collection of digital and physical prototyping of materials and methods.

Construction of Prototype Construction involved laser cutting each set of panels. Then using tape and hotglue, assembling the numbered panels in sequence (i.e. 1-10, 11-20, 21-30...). Then finally, building up the entire form using the digital model as a guide for construction.

Design Concept The idea of urban vs natural. A juxtaposition of man-made materilas, like concrete and natural elements, like plants and water.
52
Nature leaves an imprint on what is man-made, especially to the exposed surface of concrete, wether just poured or left for some time.

Prototype Fabrication Using the prototyping process established in stage 1 of design development, the mould was CNC milled, vaccum formed then cast with plaster.
FINAL PROTOTYPE
60
Prototypes used to test what surface would encourage natural growth to concrete. Also, to investigate the suitability of re-using materials like bubblewrap and styrofoam in the mold making process. This may have a positive impact on reducing widespread plasitc pollution in the environment.
Conctere prototypes allowed to weather in the natural elements.
