Company Overview

OCMA Offices
O’Connell Mahon Architects has evolved from one of Ireland’s long- established architectural practices. We provide a broad range of knowledge, skills and experience to our clients in conceptualising and realising a wide variety of projects, at every scale. We are recognised as pre-eminent in specialist healthcare design.

The quality of our work depends on a close working partnership with the client – this is the hallmark of our approach. We look for challenging opportunities to test and develop the diversity of knowledge and skills embedded in our professional team. We establish durable relationships with clients, colleagues and partners and we deliver major projects in the public and private sectors.

We invest in our knowledge base to enhance the quality of our services, by providing and availing of professional training and development, by encouraging a critical approach to the work of the practice, and by publishing our work.



Healthcare design forms a core element of the work we do. We have delivered over 100 healthcare projects to both public and private clients over the past fifteen years, often in partnership with others.

Through our continued experience and research, we have developed within our practice the expert knowledge that enables us to deliver such projects on behalf of our clients. Our approach is to see each project, whether large or small, as a challenge to develop and improve healthcare systems and designs with a view to achieving the most modern and efficient solutions to meet future needs of patients and clients.

The practice also works on a wide range of projects outside the Healthcare sector including large and small scale commercial, cultural and residential work.


The practice has, over recent years, developed an expertise in conservation works and has consolidated a reputation for detailed research and analysis together with a positive approach to the protection and conservation of our heritage within a current active and living environment.

O’Connell Mahon Architects works continually to ensure that the practice is appropriately equipped to deliver a comprehensive architectural service to all of its clients.


Conservation Accreditation

The practice has been active in the area of conservation since its inception: the past two decades have seen a growing demand both culturally and legislatively for the protection of our built legacy and an expectation that specialist knowledge and expertise is necessary in order to rehabilitate and restore our buildings and towns.

In 2004 Sean Mahon successfully completed the RIAI Conservation Module

RIAI Architecture Awards 2009
Best Health Building

Midlands Regional Hospital (Murray O’Laoire/O’Connell Mahon Architects*)
Assessment Citation
The jury were impressed by the architects’ response to an extremely demanding programme where rigorous space planning and the establishment of vital functional relationships are of the essence. Without compromising these demands a building of appropriate spatial drama has emerged. The architecture achieves an informal non-institutional image and feel; a bonus for this building type.

RIAI Architecture Awards 2007
Best Health Building

Bons Secours Hospital Galway (Murray O’Laoire/O’Connell Mahon Architects*)

Assessment Citation
This is a calm, light-filled building, on a very human scale. The roofscape is very carefully considered and unified as part of the overall landscaping of the site. While the impact of the building is subtle, the detailing and use of materials create a sense of excitement. The building is a strong addition to the hospital complex.
