Wakefield Council states "There are currently 31 of these in our district" of its conservation areas, Normanton among the names on that list, and that designation "brings with it a number of controls including: control over the demolition of buildings, strengthened controls over minor development, special provision for the protection of trees".
On listed buildings the council states that "Wakefield district has over 700 Listed Buildings", that listed building consent is needed to "alter or extend it in a way that affects its character as a building of special architectural or historic interest", and, in its own words, that "Even relatively minor works, such as painting, may affect the character of a listed building so you should always contact the Conservation Team prior to starting any works".
The national wording for an ordinary Normanton house is the Planning Portal's: "You do not need to apply for planning permission for repairs, maintenance or minor improvements, such as painting your house", while in a Conservation Area, a National Park, an Area of Outstanding Natural Beauty or the Broads "you will need to apply for planning permission before cladding the outside of your house with stone, artificial stone, pebble dash, render, timber, plastic or tiles". The Portal states as well that "If you live in a listed building, you will need listed building consent for any significant works whether internal or external".
We would explain how you check the conservation boundary, any Article 4 direction, the listed building position and the proposed work with the Wakefield Council Conservation Team before confirming whether permission is needed.
