New detached dwelling house with wastewater treatment system

Cathy and Joseph McGuinness have received conditional approval from Sligo County Council to construct a new detached dwelling at Hazelwood Demesne in the town of Sligo, County Sligo. The planning application was lodged on 8 April 2026 and the council issued its decision on 2 June 2026.

The approved scheme includes an onsite wastewater treatment system and connections to public utilities, together with all associated site works required for the development. While the council has not disclosed specific conditions attached to the approval, the decision code is listed as CONDITIONAL in the council’s planning register.

Hazelwood Demesne lies within the Sligo town area, and the new house will be a single‑storey detached residence. The McGuinnesses have indicated that the wastewater treatment system will serve the property, ensuring compliance with environmental regulations.

The decision follows a routine review process carried out by the council’s planning department. No further details about the design or construction timeline were provided in the public record at this time.

Other recent council news has highlighted concerns over a scaled‑back roads programme and an act of vandalism targeting council offices, but these matters are unrelated to the Hazelwood Demesne application.
