McCullough Mulvin Architects is an architecture and urban design practice based in Dublin. Our focus has been on the design of sustainable cultural and civic buildings - making schools, libraries, galleries, houses, and working to redefine the public realm. Every project is informed by its setting and the specific relationship between architecture and nature - shaped around landscape, the sea, the geography of small towns or the particular character of Dublin city.

The practice has an unusual combination of interest in contemporary architecture and history - based on a deep understanding of old buildings, knowledge about how they are built and how they should be conserved. We combine this with a strongly architectural vision of how modern intervention can be used to explain and enhance them, both practically and culturally. 

The work of the practice is extended by publication - on typologies (A Lost Tradition), the process of change (Palimpsest), the city (Dublin: An Urban History) and the projects of the practice - and by teaching, lectures and exhibitions in Ireland, the UK, USA, Scandinavia, Poland, Spain, Switzerland, the Czech Republic and Portugal.

In recent years the practice’s portfolio has expanded to include new international work, including Thapar University in India.
