Important: Additional Restrictions May Apply in Herefordshire

Herefordshire has 64 conservation areas. These include Almeley, Aylestone Hill, Aylton, Bircher, Bodenham, Bodenham Road. If your property is in a conservation area, some or all permitted development rights may be restricted. For example, you may need planning permission for changes that would normally be permitted, including alterations to the roof, cladding, or extensions visible from a public highway.

Herefordshire has Article 4 directions in force. Article 4 directions remove specific permitted development rights in defined areas. If your property is covered by an Article 4 direction, you may need planning permission for work that would normally be permitted. Contact Herefordshire planning department to check whether an Article 4 direction applies to your property.

Check with Herefordshire planning department before starting work to confirm whether your property is affected by any special designations.

Permitted Development Rules for a Wrap-Around Extension

Whether a wrap-around extension falls under permitted development depends on the specifics, as it must comply with PD rules for both side and rear extensions at the same time. In practice, many wrap-around extensions exceed PD limits and require a planning application.

Conditions

  • 1Must satisfy both side extension and rear extension PD conditions simultaneously
  • 2Side component must not exceed half the width of the original house
  • 3Rear component must not exceed 3m (semi/terraced) or 4m (detached) depth under standard PD
  • 4Materials must match the existing dwelling
  • 5Cumulative additions must not cover more than half the curtilage

Size and Dimension Limits

  • Side: must not exceed half the original house width
  • Rear: 3m (semi/terraced) or 4m (detached) under standard PD
  • Maximum height: 4m
  • Eaves: 3m if within 2m of a boundary

When Permitted Development Does Not Apply

  • Often exceeds PD limits due to cumulative impact, requiring a full planning application
  • Must not cover more than half the curtilage (total of all extensions and outbuildings)
  • Not permitted development in designated areas for the side element
  • Previous extensions and outbuildings count towards the cumulative limits

What About Building Regulations?

Building regulations approval is likely required

Building Regulations approval required covering all structural, thermal, ventilation, drainage, fire safety, and electrical requirements. The junction between side and rear elements requires careful structural detailing.

Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Herefordshire building control or use an approved inspector.

If your project is permitted development and you want written confirmation, you can apply for a Lawful Development Certificate (LDC) from Herefordshire. This provides proof that your project does not need planning permission, which can be helpful when selling your property.

What Happens If I Build Without Permission?

Enforcement is a significant risk for wrap-around extensions built without permission, as they are highly visible and substantially alter the dwelling. The council can require demolition. Mortgage lenders and buyers' solicitors will scrutinise these carefully.
