Why it was refused

  1. The proposed front porch, by virtue of its scale, form and projection, would appear as a prominent and incongruous addition to the principal elevation of the dwelling. The development would disrupt the established symmetry and uniformity of the terrace and would fail to preserve or enhance the character and appearance of the Wyllie Conservation Area. As such, the proposal is contrary to Policy SP6 of the Caerphilly County Borough Local Development Plan and adopted supplementary guidance relating to development within conservation areas.
  2. The submitted plans are inaccurate and fail to correctly depict the existing dwelling, particularly in respect of the position and scale of rear first-floor windows. As a result, it has not been demonstrated that the proposed development has been properly designed in the context of the existing building. In the absence of accurate and reliable plans, the Local Planning Authority cannot be satisfied that the proposal would result in a coherent and acceptable form of development or that it would not detract from the visual amenities of the area. The proposal is therefore contrary to Policy SP6 of the Caerphilly County Borough Local Development Plan up to 2021.

From the council's decision notice.
