Founded by Nizam Kizilsencer, AIA, LEED AP, WELL AP, DIA is a New York–based global architecture and design firm driven by research, innovation, and a curiosity to explore new fronts for next-generation architecture. We seek out diverse platforms and fields for fresh ideas and perspectives, transforming them into intelligent, adaptable, and culturally connected design solutions for today’s rapidly evolving world.

With over 25 years of experience in both commercial and residential design, we deliver non-generic, smart, and functional designs that reflect the identity and aspirations of brand- and lifestyle-conscious clients. Our portfolio encompasses multifamily housing, boutique cafés, specialty coffee shops, contemporary and fine-casual restaurants, vibrant urban sports and wellness facilities, including the latest wave of pickleball centers. As a trusted resource for zoning analysis and feasibility studies, we guide clients through complex regulations, unlocking each project’s full potential.

Our work is rooted in sustainability, resilience, and the creation of experiential spaces that enhance wellbeing while engaging their cultural and contextual surroundings. Whether shaping the skyline with multifamily developments or crafting intimate, iconic interiors, we approach each project as a thoughtfully designed product—streamlined, adaptable, and built to inspire.
