Sinan Kafadar was born in 1964 in Istanbul into a family outside the architectural profession. After graduating from Istanbul Technical University in 1986, he began his career abroad, working in London and later in Montreal on architecture and interior design projects, including a mountain resort for artists and musicians. These early international experiences shaped his design vision and gave him a broad perspective on architectural practice.

Returning to Istanbul in 1990, he joined Leo Design under Reşit Soley, where he met Cavit Sarıoğlu during the construction of the Robinson Hotel in Marmaris. In 1992, their collaboration led to the founding of Metex Design / Architects, where Kafadar became a partner.

In the early years of the practice, he contributed to landmark hospitality and residential projects, such as the Ritz Carlton Istanbul and Maçka Residences. One of the most significant milestones of his career was his work on the Four Seasons Hotel Sultanahmet, a project that went on to win multiple Condé Nast Traveller Awards and establish itself as one of Istanbul’s most iconic destinations.

Over the years, Kafadar has developed a portfolio spanning concept design, interior design, façade design and master planning. (Awards – yapılacak) Today, as Principal Partner of Metex, he leads the firm’s creative direction and strategic growth. Beyond practice, he regularly participates in architectural conferences, where he engages with younger generations and professionals to discuss environmental concerns, new materials, evolving architectural visions, and changing market needs.

In 2009, he published My Sketch Book, a compilation of selections from 26 sketchbooks kept between 1985 and 2008. The book documents his journey from university student to practice leader and emphasizes the role of sketching as both a design tool and a personal diary. With this publication, Kafadar aimed to share his professional evolution while inspiring younger designers to adopt the habit of carrying and using sketchbooks as a way to capture ideas, places, and moments that shape their design language.

He is an active member of the İstanbul Association of Architects in Private Practice (İstanbulSMD), serving on its administrative council, and also a member of the Idealist Interior Architects Association.
