The development will consist of: An attic conversion of habitable use to include a new metal-clad dormer window to the rear roof, a rooflight to the front roof and works to provide a new vehicular entrance from Marine Drive including partial removal of existing plinth and railings, dishing of the public footpath and associated site works. (There is an earlier application for a first floor extension to rear (ref 2085/21).
Core Planning Reasoning
The Inspector recommended a split decision: granting the attic conversion but refusing the vehicular entrance because it would remove a high-demand on-street parking space, fail to meet minimum garden depth standards leading to pedestrian safety risks/overhanging, and result in the loss of original built fabric in an Architectural Conservation Area (ACA).
Decision Maker's Conclusion
- The attic conversion and rear dormer are acceptable as they are not visible from the public realm and, subject to setback conditions, will not negatively impact the character of the Architectural Conservation Area or residential amenity.
- The proposed vehicular entrance is contrary to Policy MT14 as it results in the loss of a public on-street parking space and fails to meet the minimum 5m garden depth required for safe off-street parking, posing a risk to pedestrians.
- The removal of original period plinths and railings to facilitate the entrance would diminish the visual integrity and historic character of the terrace group within the Sandymount Architectural Conservation Area.
