Quinn Hannum is an interior architect, furniture designer, and landscape designer creating architecturally precise, highly bespoke residences, hospitality environments, and select commercial spaces for discerning private clients and developers. Her work has been featured in “Best of Style” by Philadelphia Style Magazine, the Member Spotlight by the American Society of Interior Designers, and in leading Hamptons publications including Dan’s Papers and James Lane Post.

Entrusted with substantial ground-up builds, full-scale renovations, and legacy properties, Quinn approaches each commission by first refining proportion, alignment, and flow before introducing the decorative narrative. The result is work defined by sculptural focal points, seamless transitions, layered architectural lighting, and integrated amenities that elevate both private living and guest experience.

She collaborates with master artisans and ateliers across New York, Paris, Milan, Murano, London, The Hamptons, and Philadelphia to create one-of-a-kind furniture, lighting, and collectible works. Each project is executed with discretion and precision, ensuring no two environments share the same expression.

Before founding her firm, Quinn lived in Europe for five years, refining her eye through immersive study of classical and contemporary architecture. She later joined Robert A.M. Stern Architects, contributing to landmark projects including Four Seasons Downtown New York, luxury developments for Related Companies and Corcoran Group, and the exclusive Mount Nicholson community in Hong Kong—where a residence achieved a record sale of HK$722 million. NCIDQ-certified and fluent in English and Spanish (with professional proficiency in French), Quinn serves clients seeking environments of architectural integrity, cultural depth, and enduring value.
