We are passionate about designing and delivering low-energy buildings that will be comfortable to live and work in but also affordable to build…


Andrew O’Brien Architects is an energetic and imaginative architectural practice embracing sustainable design and alternative forms of construction since foundation in 2009. With private and commercial clients throughout Ireland, we provide the qualities of a small practice with a very personal service and a high level of attention to detail while also having the vast experience and knowledge you would expect to find in a larger practice.

Our aim is to design buildings that are functional, but just as critical is the need to minimise their impact on the environment and have a high degree of energy efficiency.

We are highly regarded as being architects who produce excellence in contemporary design without compromising on your own original vision. We have a reputation for capturing the full potential of each site and through imaginative design, creating incomparable connections from new and existing internal spaces to the landscape beyond.

We are known for, and highly referred by previous clients, as being architects that have a great understanding of client requirements and an ease in communicating, not only with the client, but also with any planning authorities and potential contractors.

We will direct you through the entire building process while endeavoring to make the design and build of your development an enjoyable experience.
