Welcome to John J. O'Connell Architects

John J. O'Connell Architects is an RIAI accredited Conservation Practice, Grade I, founded in 1978. The practice is based in Dublin and has completed projects throughout Ireland, Europe and the United States.

We are an award winning practice, working primarily on historic buildings, but also bespoke new buildings. An RIAI accredited Conservation Practice. The practice is based in Dublin and has completed projects throughout Ireland, Europe and the United States.

From classical to modern, our inspiration is derived from a wide array of structures; from the traditional cottage to the grand country house, early industrial buildings to Georgian townhouses. We believe that each building contains messages that are valid for every generation.

The emphasis of our practice is that we greatly admire the work of the Architects, builders and craftsmen who have gone before us, whilst also recognising that there is forever a movement forward in Architecture. Our vision is to sensitively approach each building, whilst ensuring that they remain useful and relevant today and for future generations.

Since John J. O'Connell Architects began, we have been most fortunate to have had the opportunity to work on some remarkable buildings, large and small, which have been the work of the most thoughtful and energetic of minds. These buildings have served as a great inspiration for us.
