Design Interview

What is the main principle, idea and inspiration behind your design?

Fractal 9 was born from a humble, unexpected influence. It appeared while I was leafing through a children’s colouring book of mandalas. I found a radial figure made of squares at different scales whose order and balanced dynamism stood out. I liked it, studied it, and, by deconstructing its structure, produced the volume that became the first prototype of a piece of furniture created to make use of an space in my living room.

At first it was a functional piece with harmonious geometric aesthetics. Over time I learned that when the digital-root formula is applied to the total sum of the interior angles of regular polygons, a hidden pattern emerges. This discovery led me to analyse the model with the same formula and I found the very pattern inside it. That turning point filled the piece with meaning and let me view it from another angle, revealing a deep link among the square, the basic grid, the Fibonacci spiral, and the number 9.

I began again, redefining the design by setting clear conceptual principles that guided a new assembly system, improved functionality, and a refined aesthetic.

The project evolved into a work of contemporary design that mirrors the simplicity and complexity of nature’s fractal structures, creating a dialogue between the geometric and the organic, the rational and the spontaneous. Its sculptural presence sparks imagination, fostering a more conscious, creative, and emotional bond with the surroundings.

It features a modular system that allows it to function as an Integral Unit or split into two Essential Units to hold books, display objects, or serve as a versatile exhibition surface adaptable to many settings.

Fractal 9 moves beyond form and function to become a vehicle of artistic and symbolic expression that conveys a message of order, balance, and unity. It reminds us that we belong to a fractal nature in which every element has a purpose within a larger system. It is an invitation to look inward and ask. What is your purpose?

What has been your main focus in designing this work? Especially what did you want to achieve?

My focus was to use design as a medium, an excuse to reveal and reflect a mathematical pattern present both in nature and in the object itself.

I wanted this piece to become an experience of observation and reflection, allowing people to grasp, from another angle, the logic and beauty of natural order through its geometric and mathematical language.

What are your future plans for this award winning design?

The next step is to bring it into industrial production. My goal is to develop a manufacturing line with high quality standards, while respecting its concept, structure, and the environmental values that give it meaning.

I also plan to create an immersive installation around its concept, where design, art, mathematics, and consciousness converge. I want each visitor to feel, discover, understand, and remember life’s fractal order not as theory, but as a transformative experience.

Grand Interview

Your innovative integration of the Digital Root analysis in Fractal 9 Sculptural Shelf reveals fascinating connections with the square and golden ratio - could you elaborate on how this mathematical exploration transformed your initial furniture concept into a deeper artistic statement?

The pattern of the number 9 is no trivial matter. It runs far deeper than it may seem at first glance. It may begin as a simple numerical curiosity, but as you follow its trail and find it again and again across different systems, it reveals itself as a structural logic that runs through the natural order.The initial idea of a piece of furniture was transformed when I discovered that this pattern lived in its structure: from the square as its basic module, to the grid as its structural base, the number of modules, the radial angles, the measurements, and its connection to the golden ratio. The model stopped being just an aesthetic, functional object and became Fractal 9: a vehicle that invites observation, learning, and a questioning of the implications of this structural logic.How is it possible that we are not talking about a pattern so simple, so deep, and so beautiful, when it’s right in front of us?

The modular nature of Fractal 9 Sculptural Shelf allows transformation between an Integral Unit and two Essential Units - what inspired this versatile approach, and how does it reflect your philosophy about the relationship between form and function?

This versatile approach emerged when I discovered the model’s connection to the Fibonacci spiral. Fractal 9 fits perfectly within the first two squares of the sequence, defined by the values 1 and 1, which revealed that its modular nature allowed it to split naturally into two equivalent units. This versatility wasn’t imposed. It emerged from the structure itself.That’s where the coherence between form and function becomes clear: when the design can adapt to different spaces and needs without disrupting its internal balance. Form doesn’t serve an arbitrary function, and function doesn’t limit form. They grow together, as parts of the same language.

The sustainable materials chosen for Fractal 9 Sculptural Shelf, including FSC-certified wood and transparent acrylic, create a striking visual harmony - how did your background in visual communication influence these material choices and their interplay?

My background in visual communication taught me to observe how each element builds a message, even in silence. In this case, the FSC-certified wood of the modules reinforces the concept by offering a connection to nature. The transparent acrylic, in turn, allows for an almost invisible assembly system that preserves the structural purity of the design.Transparency is not just a visual effect. It’s a statement: what holds it up is in plain sight, there is nothing to hide. Like the number 9 pattern, which often goes unnoticed even when it’s right there. Both materials follow a logic of respect for the environment, the user, and the concept. What is seen, what is touched, and what is sensed are designed to exist in balance.

This analysis, based on the Digital Root, revealed a coherence that transcends the project itself and gave rise to an ongoing line of research. In practice, the assembly system posed a great challenge, as the solution had to be robust enough to support the structure, yet subtle enough to integrate without compromising its aesthetics and visual perception.
Research
Type of Research: Applied research. Research Objectives: To validate the geometric and mathematical consistency of the design using the Digital Root. Methodology: Quantitative analysis of angles and proportions to identify recurring patterns. Data Collection: Geometric measurements and numerical calculations to evaluate coherence.

Inspiration
Everything started with the need to make use of an empty space in the living room of my home. The goal was to create a piece of furniture that blended aesthetics and functionality, enhancing the space with a distinctive touch.

Over time, this initial model was analyzed through the Digital Root, unveiling significant numerical connections embedded in its structure. This discovery marked a turning point, leading to the conceptual design presented here: Fractal 9.
Project Duration
The first model was created in September 2019 as a personal design exploration. Over the years, it gained deeper significance, leading to structural and aesthetic refinements. In November 2024, the latest version was developed as a conceptual design with potential for future commercialization.
Operation Flow
The modular assembly is performed using an Allen wrench, enabling its transformation between an Integral Unit and two Essential Units. It adapts seamlessly to various spaces and functions serving as a bookshelf, a display surface, or a sculptural piece.

User interaction is intuitive, fostering creative exploration and customization of the environment through its flexible configuration and striking visual impact.
