Planning guidance for extensions, loft conversions, larger kitchens, dormers and family living space, with the permission route checked before design decisions become fixed.

Planning route

Before drawings go too far, check what the council will judge.

Home improvement projects often depend on small details: height, depth, roof form, overlooking, boundary relationships, conservation controls and whether permitted development rights still exist.

Useful checks

  • Permitted development or planning application route.
  • Scale, massing, daylight and neighbour amenity risk.
  • Hip to gable, dormers, windows and overlooking.
  • Conservation, Article 4 or local design constraints.
  • How to present the strongest householder submission.
01

Check the route

Confirm whether the works can rely on permitted development or need an application.

02

Reduce objections

Address scale, overlooking and neighbour impact before they become avoidable planning issues.

03

Submit with confidence

Prepare the application around the decision points most likely to matter.

Extension planning checks

Extension and loft advice before the design is locked in.

Extensions and loft conversions often turn on technical details that are easy to miss early on: depth, height, roof form, dormer position, overlooking, daylight, boundary relationships and whether permitted development rights are available.

Well Planned helps check whether a householder application is needed, whether a hip to gable or dormer proposal is likely to raise planning concerns, and how the submission should address local design policy and neighbour amenity.

Planning focus

  • Home extension planning applications.
  • Loft conversions, dormers and hip to gable works.
  • Permitted development checks.
  • Neighbour impact and design policy.
