Founded in Dublin in 1994 by DIT-trained architect John Duffy, Studio Duffy (formerly John Duffy Design Group – JDDG) has spent three decades designing environments across a wide range of sectors. To mark our 30th anniversary and the evolution of our leadership team, the practice was renamed Studio Duffy to reflect our broader expertise and collaborative approach.

Our practice thrives on the interplay of ideas across diverse sectors—from the dynamic demands of hospitality and the comfort of residential spaces to the innovation required in public and exhibition design. We use our collective experience in architecture and interiors to inform every project, crafting thoughtful, integrated solutions that are tailored to client needs, whether in the public or private sector.

John Duffy's legacy in hospitality laid a strong foundation, but today, supported by a new leadership team, we are committed to design excellence across all sectors. Our collaborative approach ensures each project balances creativity with practical considerations such as sustainability, budget, and long-term value. We take pride in uncovering opportunities beyond the obvious and providing solutions to challenges clients hadn’t anticipated.
