Trí is the Gaelic meaning for three. The name embraces the heritage and foundation of this consultancy.

Every decision has a consequence. At Trí Spatial Planning we apply the 3 pillars of sustainable development to our balanced decision making – Environmental | Social | Economic.

We apply a holistic approach to planning that goes beyond minimum standards; an approach that embraces innovation, science and knowledge and contributes to the continued improvement of our society. We are spatial planners.

We apply our skills in shaping economic, social, cultural, and ecological dimensions of society for the betterment of the environment through spatial, holistic and sustainable decision making.


To preserve the natural equilibrium, regenerate degraded environments, and create sustainable places.


Planning is involved in every aspect of life: it dictates where we live and what we live in, how we travel and where we travel to, where we work, where we meet people and where we get away from people – it sources and relocates our water, waste and energy – it is part of our everyday life and continues to make decisions that affect the environment and space we live in.

Spatial planning builds on traditional town planning principles and is the established common approach to planning practice across Europe. Compared with other regulatory land-use planning approaches, it is distinctive for: encouraging long-term strategic visions; improved integration across sectoral plans and activity; greater integration of technical & scientific information; balancing environmental, social and economic factors in achieving sustainable development; and advancing engagement with the public and stakeholders.

This holistic approach is paramount to creating a sustainable society for today and for future generations.

We want to influence planning decisions which are holistic, actually integrate sustainability at all levels of decision making, and create places that maintain the natural equilibrium of our environment.
