C+W O'Brien Architects

C+W O’Brien is a leading, award-winning architects practice and part of the Corstorphine + Wright Architects Group with 10 offices across Ireland and the UK. The Dublin branch is led by Arthur O’ Brien, who joined Corstorphine + Wright’s London office having previously ran OBK Architects in Dublin, a thriving architects practice in Ireland with a team of 70+ staff. The opening of the Dublin office was part of a programme of expansion which has continued with the opening of new offices in Glasgow, Leeds and Birmingham.

As a practice, we stand as one of the few architects with the range of skills to take projects through from conception to completion, offering both the vision to design world class schemes and the technical skills and commercial awareness required to deliver them on time and on budget. In addition to our architectural talent, we employ an in-house team of graphic designers and 3D animators who add value for clients throughout a project.

Case Studies
