The work of McGonigle McGrath is informed by a sensitivity to context and place, a consideration of form, materiality and craft, and an understanding of the quality and simplicity of buildings well made. Our passion for the contemporary is moderated by our experience in conservation and our respect for the vernacular.

Every commission is considered as an opportunity, a collaboration between architect, client and site, with a unique and individual outcome.

We engage in a critical investigation of each project's needs and constraints through dialogue, observation and research, informed by our considerable project and academic experience, with the objective of delivering the highest level of design quality, and buildings which are inspiring, practical and beautiful.

Our work is also characterised by a rigorous and analytical approach to function and planning, and a thorough process of refinement which is applied to every detail.
