Building

Your Guide To: Listed Buildings

From modern to ancient, our architecture tells a story. Building listing helps to maintain that story by preserving buildings or features that are considered to be of historic or architectural interest. The older and more rare a building is, the more likely it is to have restrictions in place.

From modern to ancient, our architecture tells a story. Building listing helps to maintain that story by preserving buildings or features that are considered to be of historic or architectural interest. The older and more rare a building is, the more likely it is to have restrictions in place.

As a general rule, if a building was built prior to 1700 and still resembles its original condition, it will be listed. Likewise, most properties built between 1700 and 1850. Buildings built over the next century can be listed if they are thought to be of special significance, while anything built over the past fifty years or so is not yet considered worth preserving. Listing buildings is led by Historic England, who have their own programme for recommending listing buildings. However, anyone can nominate a building for listing if they think that it is of historic or architectural significance. The final decision over whether or not a building is listed is made by the Secretary of State for Digital, Culture, Media and Sport (DCMS). The full list of listed buildings can be found on the National Heritage List for England (NHLE).

Gradings of Listed Buildings

It is estimated that there are around 500,000 listed buildings on the NHLE. These listings come in three categories:

  • Grade 1 listing applies to those of significant interest. Only 2.5% of all listed building are categorised as Grade 1.
  • Grade 2* applies to buildings that are of special interest, but which aren’t as special as Grade 1. Nearly 6% of listed buildings are Grade 2*.
  • Most listed buildings are Grade 2. These are of special interest because they showcase architecture or history, and as such they need to be sympathetically altered or updated.

Making Changes to Listed Buildings

Just because a building is listed, it doesn’t mean that it can’t be enjoyed, lived in, altered, extended or even knocked down. What it does mean is that you must get special permission from your local authority before you do any work.

If you want to alter, extend or demolish a listed building you may need to apply for Listed Building Consent. Before you apply, check with your local authority Conservation Officer whether you need consent for what you are planning to do. You could also ask what is likely to be granted, so that you can tailor your plans to suit the local authority’s requirement. This will mean that you are more likely to get consent the first time around, saving you time and money. Once you have made your application, the local authority will use listed building consent guidelines to make a decision about whether to grant you permission based on the property’s historical significance versus its function, condition or viability. A professional architect or reliable local builder will be able to help you to make an application for changes that are sympathetic to the existing building, and which are more likely to be accepted by the local authority.

Find clear, practical answers to common building questions, helping homeowners understand everyday issues, know what checks they can carry out safely, and when it is best to contact a qualified professional.

  • Do I need planning permission for a home extension?

    Plenty of extensions don't need planning permission - they fall under Permitted Development. Whether yours qualifies depends on the size, location, and type of build. Single-storey rear extensions up to four metres on a detached house often get the green light, but side extensions, two-storey builds, and properties in conservation areas usually do need permission. Always check with your local planning authority before you start - building without the right approvals can mean being made to undo it all.

  • What is involved in building a conservatory?

    You're looking at groundworks and foundations, the frame and glazing, the roof, and then the internal fit-out - flooring, heating, electrics. Most conservatories under a certain size fall under Permitted Development, but they still need to comply with Building Regulations, especially if you want to use the space as a proper room year-round. On the roof: solid or tiled options make a huge difference to usability - traditional polycarbonate can be unbearably hot in summer and freezing in winter. Most projects take two to six weeks.

  • Do I need a structural engineer for my home renovation?

    Not for everything - but if structural changes are involved, yes. Removing a load-bearing wall, putting in a steel beam, touching the roof structure, or adding a sizeable extension all need a structural engineer to design the solution and produce the calculations for Building Regulations approval. A builder might tell you whether a wall is load-bearing, but only a structural engineer can specify the right beam and carry professional liability for that advice.

  • Do I need planning permission to install patio doors?

    Usually not, if you're replacing an existing door or window in the same opening - that typically falls under Permitted Development. But if you're making the opening larger or creating a new one in an external wall, you may need planning permission or Building Regulations approval. Conservation areas, listed buildings, and properties with an Article 4 Direction have tighter rules, so check before assuming. Any structural work to the opening, like fitting a new lintel, needs Building Regs sign-off regardless.

  • Does my extension need Building Regulations approval even without planning permission?

    Almost always, yes. Planning permission and Building Regulations are two separate things. Extensions need to meet regulations covering structural integrity, fire safety, insulation, ventilation, and drainage - regardless of whether you needed planning approval. Your local authority's building control team can confirm exactly what's required. And don't skip it - missing Building Regs sign-off can cause real headaches when you come to sell.

  • How long does a typical home extension take?

    A small single-storey extension usually takes eight to twelve weeks from groundworks to completion. Add several months if planning permission is needed before work can even begin. Bigger builds - two-storey additions or anything needing significant structural work - can take four to six months or more. Get a realistic timeline from your builder upfront, and factor in a buffer for the unexpected.
