3560/21

Planning permission for the partial demolition, a ground and first floor extension to the side and rear of the existing dwelling and the construction of a new 2 storey, semi-detached 3 bedroom dwelling with a balcony to front, over a partial basement with a total floor area of 174.9m2. The works also include the construction of 1 additional surface parking space, a new vehicular/pedestrian entrance onto Haddington Road, connection to public utilities and drainage networks and all other associated works.

Split decision

Core Reason for the Refused Part

The proposed new dwelling constitutes overdevelopment of a restricted site that would seriously injure the residential amenities of neighboring properties (specifically No. 65 Grand Canal Street Upper) through overshadowing and overbearing impacts, while providing a grossly inadequate standard of private open space for the existing host dwelling.

  • The development would result in a significant deficit in private open space for the host house (less than 2sq.m per bedspace), representing a failure to meet basic residential standards and an overdevelopment of the site.
