Expansion and re-modelling of existing house by adding a mansard roof and upstairs

Patsy Daly of Derrinisky, Arigna, in Carrick on Shannon, applied to Roscommon County Council for permission to expand and re‑model an existing house by adding a mansard roof and an upstairs bedroom. The planning application, reference 2660232, was lodged on 19 May 2026 and was subsequently withdrawn. As a result, the council has not yet considered the proposal and no decision has been made. The application was scheduled for a decision on 13 July 2026, but the withdrawal means the council will not proceed with the assessment.

The site is located at Derrinisky, Arigna, Carrick on Shannon, N41 Y577. The applicant’s request involved structural changes to the existing dwelling, specifically the addition of a mansard roof and an extra bedroom on the upper floor. The withdrawal of the application was recorded in the council’s planning register, and the status remains listed as “Withdrawn”.

Roscommon County Council has been handling a range of planning matters in recent weeks, including approvals for new dwellings and changes of use for other properties in the county. However, the current application for the Derrinisky property is no longer under consideration.
