Across the county more than 8,000 new homes could be built as part of the Local Development Plan (LDP) currently under consideration by the Welsh Government.
Proposed sites include greenfield locations in villages and extra plots have been added to the county’s draft LDP after the Welsh Government said Denbighshire’s initial proposals were insufficient.
Mike Edwards, chair of the Keep Llangollen Special group, points out that among the sites suggested is a 0.26-hectare piece of land at Wern Road in the town which would provide space for eight dwellings.
Mr Edwards said: “This this is small scale development, but it does impinge on the greenbelt area on the lane which leads up to Castell Dinas Bran and appears to be outside the existing settlement boundary.
“On a general point there is limited scope fortunately for new development within Llangollen due to the topography.”
A recent public meeting was held in Denbigh to oppose the extra homes plan.
Opponents claim tdditional houses across the county would place an “intolerable” burden on the county’s services and infrastructure.
Amongst the additional sites are plans for 172 houses on land at HM Stanley Hospital in St Asaph, 84 on land adjacent to Ysgol Heulfre, Denbigh, 59 on land at two sites in Ruthin and 15 on land at Cynwyd.
Other sites are at Bodfari, Cyffylliog, Dyserth, Llanarmon yn Iâl, Llanbedr DC, Llanfair DC, Llangollen, Llanrhaeadr, Prestatyn, Rhuallt and Rhuddlan.
A hearing on the LDP is due to take place in late January.
