Planning Permission to a). convert attic space for storage use and ext

Granted

Core Planning Reasoning

The Inspector concluded that the proposed dormer was not sufficiently subordinate to the host dwelling, as it was designed to meet the ridge level and occupied an excessive proportion of the roof plane, thereby failing to meet the development management standards of the Fingal Development Plan 2023-2029.

Decision Maker's Conclusion

  • The design of the dormer as proposed lacks subordination to the dwelling roof and rear elevation, having an unbalancing and dominant impact on the architectural composition of the house.

  • The Planning Authority's Condition 3, requiring a reduction in width and a set-down from the ridge, is necessary and appropriate to ensure the development is subordinate and consistent with the current Development Plan.
