Whilst ADELI is a consummate cosmopolitan, with global tastes and experience his creative work and business ethic retain a distinctive SWISS character – embodying the nation’s idiosyncratic traits of reliability, excellence, attention to detail and rigour.

Established in 1999 in Lausanne – Switzerland, ADELI Interior Architecture & Partners LTD provide their clients with a CREATIVE APPROACH to developing Exclusive interior architecture projects. Their design develop a VISUAL IDENTITY adapted perfectly to the culture and practices of their clients.


SIAVOSH ADELI is a Swiss interior architect and the main shareholder of his company, ADELI Interior Architecture & Partners Ltd. He began studying Visual Arts in 1991 before bringing his talents to the world of architecture.
In 1996 he obtained his diploma from the “Athenaeum” School of Architecture in Lausanne, a prestigious school established by the famous Swiss architect Alberto Sartoris.
After graduating, he worked at two important architecture studios before
setting up his own company, Adeli & de Rham, in association with his schoolmate Joakim de Rham. They soon became a highly sought-after creative duo, working for many major companies including British American Tobacco, Tag Heuer and Mövenpick.
Between 1999 and 2003 interior architecture work was a highly effective part of the marketing strategy of these big-name multinationals.

In 2004, the two designers left Switzerland to conquer Dubai. On their return the two parted ways. Joakim de Rham moved to the United Arab Emirates and set up the Swiss Bureau Interior Design office, whilst Siavosh Adeli remained in Switzerland, transforming Adeli & de Rham into the limited company « Adeli Interior Architecture & Partners », becoming the company’s main shareholder.

“Partners” is key here.

Beyond its creative work, a profound strength of Adeli’s company is its sterling ability to find and work with the most excellent specialised companies in the field.
Adeli has a gift for sourcing the best people in the business the right Engeneers, carpenters, electricians, AV companies, builders, furniture manufacturers and so on. This guarantees excellence even in the finest details of their work and enables them to meet the expected budget.

From 2008 to date, Siavosh Adeli worked on a number of highly prestigious architecture projects. More than a interior design firm, it is a laboratory that invents the stunning « Emirates Room » at the United Nations Office in Geneva and the breathtaking headquarters of the Federation Equestre International in Lausanne created for Princess Haya. He also works on interior design (turn key) projects, creating luxury chalets and villas for VIP Swiss residents, as well as nightclubs like as the D!
