House extension and alterations plus new waste water treatment system

Daniel O’Hara and Shauna Smith have secured conditional approval from Mayo County Council to extend and alter their house at Quignalecka in Ballina, Co Mayo, and to install a new waste‑water treatment system for the property’s sewage. The application was lodged on 13 May 2026 under reference 2660377 and the council set a decision deadline of 7 July 2026. On 29 June 2026 the council issued its decision, granting approval subject to conditions.

The approved works include an extension to the existing dwelling, alterations to internal layout and external facades, and the installation of a new on‑site waste‑water treatment system designed to manage domestic sewage. The planning file notes that various site works will be required to complete the project, including excavation, drainage alignment and necessary civil engineering works.

The conditional nature of the approval means that O’Hara and Smith must comply with any conditions imposed by the council before construction can commence. These may involve detailed design submissions, environmental assessments or compliance with local planning guidelines, although the specific conditions are not listed in the publicly available summary.

Ballina residents will see a modernised property that incorporates contemporary waste‑water management technology, aligning with broader efforts to improve sustainability and infrastructure within the county. The project is expected to enhance the functionality of the home while ensuring it meets current environmental standards for sewage treatment.

The council’s decision reflects its ongoing commitment to reviewing residential development proposals on a case‑by‑case basis, balancing individual homeowner needs against community interests and regulatory requirements. While the approval is conditional, the timeline suggests that construction could begin shortly after any remaining conditions are satisfied.
