Let's know each other

Our Design Philosophy

Architects are storytellers at heart.


Some stories need to be written from the ground up;
others are ready to transform and evolve.
Our team is both deeply skilled and genuinely passionate about crafting new narratives through architecture, and reshaping existing ones through interior design.

Architect Feyza Yeniay

She is a graduate of the Department of Architecture at Çukurova University, Faculty of Engineering and Architecture (2010). After completing her education, she relocated to Istanbul to further develop her professional career. While actively working in the field, she attended specialized courses at Mimar Sinan Fine Arts University, focusing on high-rise buildings, ecological architecture, and timber structures.

Throughout her career, she has taken part in projects of various scales and typologies, including Istanbul Airport, Peninsula Istanbul, congress centers, hotels, large-scale residential complexes, as well as corporate office buildings and industrial facilities.

In 2014, driven by her research on environmentally conscious architectural practices and her pursuit of language education, she spent time in London. During this period, she held a photography exhibition titled “The Seed of Evergreen.” She continues to produce content with a strong focus on environmental awareness and sustainability.

Motivated by a desire to collaborate with diverse teams across different scales and sectors, she founded Herdemyeşil Architecture. Throughout this journey, she has received support and mentorship from various institutions and organizations, including the Small and Medium Enterprises Development Organization of Turkey (KOSGEB), the Women Entrepreneurs Association of Turkey (KAGİDER), the Human Development Foundation of Turkey (İNGEV), and Habitat Association.
