The Planning Inspectorate has backed the Snowdonia National Park after it refused proposals to build two holiday lets in Aberdyfi. The pair of semi-detached houses had been earmarked for a disused quarry at Craig-y-Lanch on the A493 leading into the village. Submitted by Shrewsbury-based Les Stephan Planning Ltd, the outline plans were turned down by the park authority in July 2020 after similar proposals were also refused in 2018. But after an appeal was launched with the planning inspectorate, an independent review has now fallen on the side of the park after inspectors remained unsatisfied with aspects of the proposals.
