JOHN O'NEILL & ASSOCIATES ARCHITECTS AND INTERIOR DESIGNERS LIMITED

John O'Neill & Associates Architects and Interior Designers Ltd. is a Dublin-based practice that has been shaping contemporary Irish architecture since 1990. Founded by UCD graduates John O'Neill and Ros O'Loughlin, the studio has built a reputation for innovative, award-winning design across a diverse portfolio that includes residential, hospitality and commercial projects.

The firm offers a full suite of architectural and interior-design services, applying a forensic, detail-oriented approach to each brief to deliver unique, context-sensitive solutions. Current work ranges from the adaptive reuse of a protected Georgian building for a new guest house on Lower Baggot Street, to multi-storey apartment schemes in Neilstown, intensive green-roof design for the Skylon Hotel, and bespoke extensions and renovations throughout Dublin and beyond. Their expertise also extends to feasibility studies and the addition of extra floors to existing structures, demonstrating a strong capability in both new build and complex retrofit projects.

With a focus on creativity, sustainability and client collaboration, John O'Neill & Associates continues to contribute thoughtfully designed spaces that enhance the built environment across Ireland.
