The FEI Headquarters, also known as the HM King Hussein I Building, stands as a tribute to a visionary leader and to the global legacy of equestrian sport.
Named in honor of the late King Hussein of Jordan, the project was made possible through the support of Princess Haya bint Al Hussein, President of the FEI, whose commitment reflects both heritage and future ambition.
The project consists of the transformation of an existing 1960s building, where the façade was reinterpreted and the interior entirely redesigned. Siavosh Adeli collaborated with KCA International and architect Hervé de Rham to create a contemporary and dynamic architectural identity.
Designed according to Swiss MINERGIE® standards, the building integrates advanced environmental strategies, reducing energy consumption while aligning with the FEI’s commitment to sustainability.
The architectural concept draws inspiration from the movement of the horse. Linear wooden elements and light compositions create a rhythmic spatial experience, translating motion into architecture. Light and shadow interact across surfaces, generating a sense of fluidity, energy, and elegance.
At the heart of the project, the atrium acts as a central connector between floors, enhancing circulation and visual continuity. Custom-designed lighting elements reinforce the identity of the space while creating a strong visual impact upon entry.
The main conference room combines technological performance with a refined and formal atmosphere, while secondary meeting rooms introduce varied identities inspired by equestrian themes.
A dedicated wellness and “Zen” area offers a calm retreat for employees, supporting well-being within the workplace. In parallel, the museum space presents the history of the FEI through immersive scenography, projections, and curated displays of trophies, bridging past, present, and future.
The project embodies a balance between performance, sustainability, and symbolic expression, translating the spirit of equestrian sport into a contemporary architectural language.
