B-KD (Büro Koray Duman) is a research-driven architecture and design studio based in New York City and Istanbul. We believe that architecture should be functional and unexpected; engaging and poetic; and experimental and affordable. Combining innovative design solutions with socially conscious ideals, we aim to redefine the relationship between contemporary architecture and the complexity of urban intervention. We pride ourselves on promoting awareness of cultural diversity through the participation of urban communities while navigating intricate spatial constraints to activate underutilized urban environments.


  • We create spaces for the production of emerging cultural narratives.
  • We strive to design hybrid public spaces that perform in multiple ways.
  • We act as instigators of change, progress, and innovation.
  • Our research projects tackle the challenges of repurposing underused or obsolete urban infrastructure to plan for a dynamic, vibrant future of lasting value.
  • We cross boundaries and overcome barriers. We embrace collaborative work and seek out audacious community partners.
  • We favor a considered and sensitive design approach that strives to apply and critically communicate evidence-based research findings through bold spatial and cultural narratives.

B-KD works across all typologies and scales. We are developing a transcendent vision of architecture. If it challenges us, we’re on board.

We have created spaces for artist Richard Prince, American Society for Muslim Advancement, Council for Fashion Designers of America and Design Within Reach. Our work has been featured in publications like the New York Times, Los Angeles Times, Surface Magazine, Cultured Magazine, Interior Design Magazine, Architectural Record and Dwell.

In 2017, Architizer honored B-KD as Emerging Firm of the Year for ‘its forward-thinking vision for the role of the architect and the desire to disrupt the stigma of the practice’.  We received the 2017 Design Award of Excellence by Society of American Registered Architects, 2015 Best of the Year Award by Architect’s Newspaper and HIP Award at NeoCon 2014. 

In 2016, we were selected for the NYC Department of Design & Construction’s DCE (Design and Construction Excellence 2.0) program.

B-KD is an LGBTQ-owned company. The studio was established in 2012 by Koray Duman and has a team of architects that represent a diverse mix of nationalities and experiences from around the world.
