Generations of design
O’Connell Mahon Architects was established in 1998 building on the legacy of Brian O’ Connell Associates a practice with a strong healthcare portfolio, the seeds of which go back to Brian’s first job with T.P. Kennedy Architects as clerk of works on the Coombe Hospital in 1966.
The objectives of our founding directors Brian O’Connell and Sean Mahon were to provide the knowledge, skills and experience necessary to deliver quality architecture and establish and maintain durable relationships with clients, colleagues and partners to deliver major projects in the public and private sectors.
Over the years the practice has grown as has the size of the projects we deliver. Through our work on a number of large scale national projects we have developed skills, processes and experience that position us to lead any scale and complexity of work in the healthcare sector.
We have the great fortune to be able to draw from the depth of knowledge accumulated by our highly experienced team many of whom have been working for the practice for over 20 years and the information retained in our unrivalled database of information on healthcare projects from almost 30 years of working on hospital campuses.
Brian O’Connell, our late founder, had over the course of his lengthy career accrued a uniquely broad and profound expertise in the architecture, conservation and legal realms. The breadth of Brian’s knowledge and experience in all aspects of the industry, which he generously shared, and his lifelong dedication to academic excellence has contributed significantly to who OCMA are. His example has been one that has become the benchmark that we as a practice continually strive for.
From architectural design to clinical planning, our comprehensive expertise ensures tailored solutions for every project phase, delivering excellence with meticulous attention to detail.
