Our design ethos is founded on - creativity, collaboration and context

About us

Howley Hayes Cooney is a Dublin based practice that combines many diverse talents, with a belief that – great architecture creates a sense of time and place that enriches our lives. Throughout thirty-five years of practice we have established a strong design ethos with particular emphasis on creativity, collaboration and context. Our work includes - the design of new contemporary buildings; the adaptive reuse of existing buildings and the creative conservation of many important historic buildings and places. Each project is approached with an open mind as we develop our designs in close conversation with our clients and other designers. We have earned a strong and trusted reputation from our clients, peers, consultants and others with whom we collaborate, and the quality of our work has been recognised through many national and international awards. 

Our story began in 1987 when James Howley established his first studio, working as a sole practitioner in London. After relocating to Dublin he co-founded Howley Harrington Architects in 1996, before establishing Howley Hayes Architects with Fionnuala Hayes in 2005. The practice continues to evolve and grow as Howley Hayes Cooney with Conor Cooney joining as a director in 2016. In 2022 Lucy O’Connor became a director and Marc Kilkenny an associate, further expanding our expertise. We are now a medium sized studio with our senior team collaborating in the design and delivery of all projects.
