A: It depends on which part of Llandudno your property is in:
There are 3 areas: Old Llandudno where building lines are determined by the Amended Zoning Scheme for Llandudno. Extension 3 and Extension 12 both of which have Title Deed Conditions restricting building lines as well as the Zoning Scheme. Ask LCA for the Zoning Scheme and get out your title deed!
