HELIX is a diffuse furniture system that generates a continuous interior space by adapting simultaneously to any vertical and horizontal surface while defining an immersive spatial atmosphere. Its form recalls a natural system that emerges from the structure beneath. HELIX is modular and can be aggregated in different forms following the logic of spatial branching and growth. The spatial pattern is generated through the repetition of vertical zones (A and B) of the same base module that generates the 3D macro-aggregate surface cut through planes that emphasize the perspectival views of the sequence from the corridor to the interior space. The system morphs the space allowing the viewer to follow the visual continuous trajectory generated by the wrapper (wall + ceiling). The aggregate surface adapts in response to the specific site conditions and programmatic requirements with each module shaped by scripted rules. It is manufactured through iterative procedures guided by a 5-Axis CNC wire cut. HELIX is made of EPS- expanded polystyrene obtained by corn; it is completely recyclable and the manufacturing process helps to reduce CO2 emissions allowing the project to be completely executed through fully sustainable processes. The structure is lightweight yet highly resistant due to the resin finish. The modules were prefabricated and organized into zones to be easily assembled on site. It is adaptable to any type of interior space, from retail, exhibition, workplace to residential. HELIX investigates the notion of space-atmosphere, adaptability, reuse, and sustainable manufacturing processes within the context of a public interior condition. The project has been selected to be exhibited at the 2014 and 2015 Milan Design Week, it is the winning project of the eVolo-Vmodern competition, and has received the "Project of note in Sustainability"award of the American Institute of Architects among others.
