Why it was refused

  1. The proposal, by virtue of its size, scale, materials, design and finish would fail to respect the existing setting having an unacceptable adverse impact on the host dwelling and wider landscape views. Therefore, the proposal is contrary to policies DES1 and H6 of the adopted Local Development Plan.
  2. The proposal has failed to provide adequate information with regards to biodiversity enhancement and would therefore be contrary to the requirements of Planning Policy Wales (Edition 12, 2024), Chapter 6: Distinctive and Natural Places.
