Dungannon and South Tyrone Area Plan 2010
Dyan is located approximately 14 kilometres south of Dungannon (see Map No. 81). It has developed in linear form along the B45 Dungannon to Caledon Road. The settlement has a small number of houses. Services and facilities are limited to a hall and a fuel distribution plant. The settlement has considerable character due to its mill complex that is listed.
Single dwellings of an appropriate design will normally be acceptable on suitable sites within the settlement limit provided the proposal does not prejudice the comprehensive development of adjacent land. Housing development will normally be permitted provided the scale, layout and detailed design of the development are compatible with the scale and character of the settlement. Accordingly, residential developments in excess of five units will not normally be permitted.
In order to reinforce local identity, all residential proposals should be guided and informed by the traditional rural built forms in the locality. Housing developments should reflect the essentially informal rural character of the settlement and not lead either individually or cumulatively to large-scale suburban estate type layouts. The use of designs and materials unrelated to the surrounding rural locality will not be acceptable.
