All house prices in FlintshireConservation areas in Wales are not included yet.
In a conservation area you usually need planning permission for work that would be allowed elsewhere, such as cladding, side extensions, some roof changes and demolishing most buildings, and you must give the council six weeks' notice before cutting back or felling most trees. Some areas have extra Article 4 rules, for example on replacing windows or doors. Check with the council before you buy.
A listed home needs listed building consent for any work that affects its character, inside or out, and doing that work without consent is a criminal offence. Grade I buildings are of exceptional interest (about 2.5% of listed buildings), Grade II* are particularly important (about 5.8%), and most, about 92%, are Grade II. One list entry can cover a whole terrace.
