Building work in conservation areas and on listed buildings in Northumberland

Northumberland is rich in historic buildings. Towns such as Alnwick, Berwick-upon-Tweed, Hexham and Morpeth have large conservation areas and many listed buildings, and listed farmhouses, cottages and barns are scattered across the county. If your home is one of them, you can still extend, adapt and improve it – but there are extra rules, and planning around them early saves time and money.

Is your home listed or in a conservation area?

The National Heritage List for England, run by Historic England, shows whether a building is listed and why. Conservation area boundaries are published by the council. If you are unsure, check before you design anything.

Listed buildings

Listing protects the whole building, inside and out, plus fixtures and some structures within its grounds. Most alterations that affect its character need listed building consent from the council, including:

• extensions and demolitions;
• replacing windows and doors, or changing their design or materials;
• changing roof coverings, chimneys or rainwater goods;
• internal changes such as removing walls, fireplaces, panelling or staircases;
• some repairs, if they change materials or appearance.

Like-for-like repairs often do not need consent, but the line is not always obvious. Unauthorised work to a listed building is a criminal offence, so if in doubt, ask the conservation officer first.

Conservation areas

In a conservation area, permitted development rights are reduced. Depending on the area, you may need planning permission for side extensions, some rear extensions, dormers, cladding, satellite dishes and other changes. Demolition needs permission, and trees are protected – you must normally give the council six weeks' notice before carrying out work to a tree. Some conservation areas also have "Article 4 directions" removing further rights, for example to replace front windows.

What gets approved?

Every case is different, but successful applications usually share some features:

• Extensions that are subservient to the original building – lower, smaller and often to the rear.
• Materials that match the original, such as stone, natural slate and timber, or a deliberately high-quality contemporary contrast.
• Keeping historic features and fabric, repairing rather than replacing.
• A clear explanation of the building's significance and how the proposal affects it – often in a heritage statement.

Using the right materials

Historic buildings are best repaired with materials that work with their original construction: lime mortars and plasters, natural slate, matching stone and traditional timber joinery. Modern, impermeable materials often cause damp and decay in old buildings.

Practical tips

• Get pre-application advice from the council for anything significant.
• Use a designer with heritage experience.
• Allow time for consent and for conditions to be discharged before work starts.
• Keep records of consents and approved details for when you sell.
