Based in Dublin, McCullough Mulvin is an architectural practice experienced in every kind of award-winning project at large and small scale. Its particularity is based on a wide reach - a will to make original and interesting architecture, singular works of their place and time. There is no issue of scale and no house style, more a consistency of exploration. The practice is collaborative, experimental and open. Clients form part of the team - the end result reflects that dynamic exchange.

Our approach is founded on an investigation of the idea of place. Whether this is a city, a site, a history, or a story - using that germ like a landscape to make timeless contemporary structures which play with forms in nature.

The practice is unique in combining Grade 1 conservation skills with cutting edge contemporary design - making innovative projects that fully integrate old buildings and new architecture. This work is sustainable in nature and at the forefront of 21st century debate about the re-use of old fabric. 

The practice is also dedicated to making in its native city of Dublin, interpreting the tradition of the city in contemporary work, exploring its capacity to make architecture which is “of” the place. This is evidenced in Trinity College, where the practice has contributed three buildings to its formal grid, and in the many projects in the streets, squares and mews of the Georgian city around it.

McCullough Mulvin combines architectural practice with parallel studies in art, literature and film, explorations which reverberate in the background of project-making - a sensibility brought to bear in conversations about the design of new work. There is a strong affinity with Spanish and Portuguese contemporary design - recognised with the publication of a Spanish monograph on the work of the practice in 2015 and a solo exhibition in Portugal. The practice has exhibited widely in Europe and has been awarded many international awards including shortlisting for the Mies van der Rohe award, and the American Architecture Prize, as well as many Irish citations.


McCullough Mulvin has experience in every kind of building project and has consistently achieved awards for work, and more significantly, a high level of client and user satisfaction.

Projects include educational and research buildings for Ireland’s leading universities, along with public buildings such as libraries, museums, fire stations and art galleries for government and local authorities. Residential work includes private houses, apartments and student residences. The practice has also designed healthcare and sports projects, offices, hotels, mixed-use and masterplan projects.

The projects are of every scale. Current work including the 11,000sqm Oisín House sports, healthcare and student residences for Trinity College Dublin, and the 60,000sqm Student Learning Centre for Thapar University in the Punjab, India, ranging to smaller and more intimate designs for single houses, exhibitions, even single rooms.
