The proposal is considered to constitute sporadic development in the open countryside and be contrary to Strategic Policy B and Policy CO12 of the NYM Local Plan and Part 4 of the Design Guide (Supplementary Planning Document) due to: lack of a demonstrated essential need for an agricultural or rural worker, the absence of an existing residential unit at the site, proposed principal residence occupancy, lack of structural survey relating to the proposed permanent dwelling, excessive number of rooflights and inadequate infrastructure leading to conflict with the use of the public bridleway. The proposed development is therefore considered to be unsustainable and harmful to the special qualities of the North York Moors National Park.
