Why is Planning Permission Important?

Planning permission ensures that your building project complies with local regulations, protects property values, and avoids costly legal issues down the line. Securing permission at the right stage allows your project to move forward smoothly, with confidence that all structural, environmental, and zoning requirements are fully met.

How is Planning Permision Done?

At O’Neill O’Reilly and Associates, we manage the entire planning permission process from start to finish. We begin with a detailed consultation and site assessment, followed by the preparation of all required drawings, reports, and documentation. Our team then submits the application to the local authority on your behalf and handles any follow-up queries or additional information requests. With expert knowledge and careful attention to detail, we streamline the process to help ensure a smooth and timely approval.
