Conservation Areas in North Hertfordshire District Council

What is a Conservation Area?

A conservation area is an area designated by the local planning authority under the Planning (Listed Buildings and Conservation Areas) Act 1990 as having special architectural or historic interest. The aim is to preserve and enhance the character and appearance of these areas for future generations.

Conservation areas can include town centres, historic villages, Victorian suburbs, garden estates, and even industrial heritage sites. They are not just about the buildings themselves — they also include the spaces between buildings, trees, street furniture, and the general character of the area.

Coverage varies by provider and can change. Absence from this list is not proof that land is outside a conservation area; the council's map and designation documents are authoritative.

How Conservation Areas Affect Your Planning Rights

Living in a conservation area does not mean you cannot make changes to your home — but it does mean that some works which are normally permitted development will require planning permission. The following permitted development rights are removed or restricted in conservation areas:

• !Cladding the exterior of a house with stone, render, timber, plastic or tiles is not permitted development on article 2(3) land.
• !A roof enlargement cannot project beyond the plane of the principal or side roof slope where it fronts a highway.
• !Side extensions and certain two-storey extensions face tighter permitted-development limits.
• !Outbuildings at the side of a house are not permitted development on article 2(3) land.
• !Relevant demolition may require planning permission, and listed buildings have a separate consent regime.
• !You must normally give the council six weeks’ notice before specified work to trees, unless an exception applies.
• !An Article 4 direction can remove additional rights, but only for the development and area stated in the direction.
