The development will consist of: (i) demolition of existing, single storey structure on-site; (ii) construction of a two-storey over basement level, three-bedroom contemporary style, flat roofed, detached dwelling. The dwelling will be provided with private amenity space in the form of front and rear patio spaces at ground floor level and a terrace area at first floor levell; (iii) provision of new vehicular and pedestrian entrances from Lansdowne Lane and 1 no. car parking space comprised within the proposed garage at ground floor level; and (iv) drainage, landscaping, boundary treatments and all ancillary works necessary to facilitate the proposed development.

Refused

Core Refusal Reason

The proposed development constitutes overdevelopment of a restricted site that fails to provide adequate qualitative or quantitative private open space and would result in significant overbearing impacts on the adjoining residential property at No. 10/10a Lansdowne Terrace.

Decision Maker's Conclusion

  • The subject site is not sufficiently large to accommodate a fourth mews-style dwelling without representing an inappropriate form of overdevelopment that injures the character of the Residential Conservation Area.
  • The proposed separation distances, specifically the 1.5m gap between the new gable and the existing return of No. 10/10a, are inadequate and create an unacceptable overbearing impact on the original property's rear garden.
  • The proposed private open space (calculated at 30-38 sqm) is significantly below the 60 sqm requirement for a three-bedroom house, and the Inspector rejected the applicant's argument for 'inner city' standard relaxations based on the site's distance from the Grand Canal.
