About

ADELI is a Swiss architecture and interior design studio based in Switzerland, with projects across Europe and the Middle East.

Founded by architect Siavosh Adeli, the practice develops a refined and cosmopolitan approach shaped by diverse cultural perspectives and grounded in Swiss precision. The studio operates across architecture, interior architecture and design, engaging with projects ranging from institutional and diplomatic environments to private residences, hospitality and luxury retail.

At its core, ADELI explores how space is experienced, not only as form, but as atmosphere.

Each project is conceived as a balance between clarity, rigor and expression, where architecture, light and materiality come together to create coherent and immersive environments.

Since 2008, the studio has developed an international portfolio across Switzerland, Europe and the Middle East, with notable work in Geneva, Lausanne and Montreux, alongside high-end residential, hospitality and luxury retail projects.

CREATIVITY & EXCELLENCE

Every project begins with a conversation.

Through dialogue and shared ambition, ideas are distilled to their essential qualities, precise, intentional, and enduring.

Working closely with artisans and specialists, the studio remains engaged throughout every stage, ensuring coherence, quality and fidelity to the original vision.

Architecture becomes not only a response, but an experience.

AREAS OF EXPERTISE

ADELI works across a wide range of contexts and scales, from the renovation of existing residences to the design of interior, commercial, hospitality and institutional spaces.

Each project is approached with the same architectural rigour, combining creativity, precision, a clear understanding of use and a high standard of execution.

Some projects are carefully designed. Others become part of history.

ARCHITECTURE, INTERIORS & DESIGN AS ONE DISCIPLINE

Architecture is not separate from its interior, it extends through it.

Projects move fluidly between architecture, interior architecture and design, forming a single, continuous discipline.

Each intervention is conceived as a unified system, where structure, material and detail are intrinsically connected.

Across institutional and diplomatic commissions, as well as residential and hospitality projects, ADELI operates at multiple scales while maintaining a precise and recognizable architectural language.

RECOGNITION

ARCHITECTURE THROUGH INSPIRATION

Inspiration is not a starting point, it is a continuous process.

Each project is conceived as an exploration, where ideas are transformed into distinct architectural environments.

Rather than imposing form, the approach reveals it, allowing space to emerge through light, proportion and material presence.

Architecture is not only built, it is discovered.
