House extension and alterations plus new waste water treatment system

Daniel O’Hara and Shauna Smith have applied to extend and alter their house on Quignalecka in Ballina, Co Mayo, and to install a new waste‑water treatment system to manage sewage from the property. The proposal includes a range of site works required to complete the project.

The planning application was submitted to Mayo County Council on 13 May 2026 under reference number 2660377. It covers an extension to the existing dwelling, alterations to internal and external spaces, installation of a new waste‑water treatment plant, and all associated site works such as drainage and access improvements.

Mayo County Council has issued a conditional decision on the application. The council’s decision was made on 29 June 2026, with a decision code of “CONDITIONAL” and an expected completion date of 7 July 2026. The approval allows the owners to proceed subject to any conditions set by the council, which may include further site works or environmental safeguards.

The project is part of ongoing residential development in Ballina, reflecting the town’s continued growth while addressing local infrastructure needs. While the council has granted conditional approval, it remains to be seen how any potential flood concerns will be managed as the work progresses.
