House extension and alterations plus new waste water treatment system

Daniel O’Hara and Shauna Smith have secured conditional approval from Mayo County Council for a substantial redevelopment of their home at Quignalecka in Ballina. The planning application, reference 2660377, was lodged on 13 May 2026 and the council’s decision was issued on 29 June 2026, with the formal decision due by 7 July 2026.

The approved scheme involves an extension and alterations to the existing dwelling, together with the installation of a new waste‑water treatment system to manage sewage on the property. The council’s decision notes that a range of site works will be required to complete the project, although the specific details of those works are not yet finalised.

The conditional nature of the approval means that the council has set certain requirements that the applicants must satisfy before construction can commence. These conditions are typical for projects that involve significant changes to a property and the introduction of new infrastructure such as a waste‑water treatment plant.

The decision reflects the council’s willingness to support residential development that incorporates modernised infrastructure, provided that the necessary safeguards and conditions are met. The O’Hara and Smiths will need to address the council’s conditions and secure any further permits before they can begin the construction phase.
