CAAA Restaurant by Pietro Catalano: A Fusion of Gastronomy and Avant-Garde Design

The CAAA Restaurant by Pietro Catalano, designed by the Barcelona-based architecture firm External Reference, represents a groundbreaking collaboration between architecture and haute cuisine. Led by Italian PhD architect Carmelo Zappulla, the team was tasked with creating a unique gastronomic space for Lucerne, Switzerland, merging immersive design, advanced technology, and culinary artistry.

A Design Inspired by the Alpine Landscape

Occupying 85 m² and accommodating up to 16 diners, the restaurant showcases a refined white-dominated interior palette, drawing inspiration from the snow-capped Alps and the serene beauty of the transalpine region. Every element within the space is carefully curated to echo the purity and calmness of a winter landscape.

The ceiling, composed of custom 3D-printed organic pieces, mimics the flowing curves of snowdrifts, enveloping visitors in a dynamic yet serene atmosphere. A luminous cavity integrates light design, simulating the subtle chromatic effects of sunlight on snow, creating an environment where guests experience dining as a sensory journey through nature.

Custom Furniture and Material Innovation

Every piece of furniture at CAAA is custom-designed, reflecting the delicate tones and textures of the Alpine environment. Ash wood was selected for chairs and tables to evoke the elegance of forest branches, while stainless steel, glass, and marble complement the bar, enhancing the overall minimalist aesthetic.

The adoption of a monochromatic color scheme allows architectural elements to highlight the culinary creations of Pietro Catalano without distraction. Cellulose, with its bone-colored natural tone, forms the primary material, providing both aesthetic subtlety and ecological responsibility.

3D Printing and Parametric Design in Architecture

The project exemplifies the integration of digital design and parametric modeling. External Reference analyzed snow-covered morphologies digitally to create the ceiling’s intricate structure. Divided into 63 modular pieces, each 80x80 cm, the ceiling was 3D-printed in cellulose, a sustainable biomaterial derived from wood waste.

Cellulose, combining lignin and natural fibers, offers excellent mechanical properties suitable for high-quality 3D printing. It is biodegradable, recyclable, and even capable of storing CO2, underscoring the restaurant’s commitment to sustainable architecture. This innovative approach was executed with the expertise of La Máquina, marking a significant milestone in the application of 3D printing to interior design.

AI and Innovation in Architectural Process

Beyond physical materials, the project reflects the role of artificial intelligence in modern architectural practice. Tools like DALL-E and MidJourney were used to translate conceptual ideas into visual outputs, demonstrating how AI can complement the creative process. Carmelo Zappulla emphasizes that AI allows designers to visualize concepts that were once restricted to sketches, enabling new narratives in spatial design.

Experiential Dining Through Design

The collaboration between Pietro Catalano and External Reference transforms design into a key ingredient of the dining experience. The restaurant’s architecture not only frames culinary creations but actively enhances them, offering visitors a holistic sensory journey. The interplay of natural materials, advanced technologies, and parametric design creates a space where gastronomy and architecture converge seamlessly.

CAAA Restaurant sets a precedent for avant-garde interior design, combining sustainable materials, parametric innovation, and immersive spatial storytelling. It stands as a model for the future of restaurant architecture, where creativity, technology, and culinary excellence intersect.
