Yonca Sirmen Interior Architecture

Yonca Sirmen Interior Architecture is an Istanbul-based interior design practice creating thoughtfully designed spaces since 1998. Our work focuses on restaurants, hotels, corporate offices, retail and selected residential projects, with an approach that combines concept development, functionality, brand identity and implementation know-how.

We believe that a successful interior is not only visually refined, but also supports the way people experience, use and remember a space. For this reason, each project is developed through a careful evaluation of the client’s vision, operational needs, target audience and the unique potential of the location.

Our studio provides a comprehensive design process from concept creation and space planning to 3D visualization, technical drawings, material selection, budgeting, coordination, and site supervision. With more than two decades of experience, we aim to deliver spaces that are aesthetically strong, functionally resolved, and professionally executed.

Based in Istanbul, Yonca Sirmen Interior Architecture works with both local and international clients across hospitality, commercial, and residential sectors.

1998 yılından bu yana farklı ölçeklerde geliştirdiğimiz projelerde, tasarım kararlarını estetik, işlevsellik ve uygulama disipliniyle birlikte ele alıyoruz. Her mekanı, kullanıcı deneyimi, operasyonel ihtiyaçlar, marka dili ve bulunduğu bağlam doğrultusunda değerlendirerek kendine özgü, dengeli ve nitelikli çözümler üretmeyi hedefliyoruz. İstanbul merkezli ofisimiz, Türkiye’de ve yurtdışında seçili projelerde konsept geliştirmeden uygulama sürecine kadar bütüncül bir yaklaşımla çalışmaktadır.
