Extend your living space Without The Need For Planning Permission

Installing a glass veranda is a great way to extend your living space, but are you allowed to do it without planning permission? In many cases, yes — but there are limits. In 2025, most glass verandas are still covered under Permitted Development Rights (PDR), but homeowners must ensure they stay within the guidelines to avoid needing formal approval.

Permitted Development Rights for Glass Verandas

Under PDR, a veranda can be added to the rear of a residential property without planning permission if it:

  • Does not extend more than 3 metres from the original rear wall (or up to 6–8 metres under Prior Notification)
  • Is no higher than 4 metres (or 2.5 metres if within 2 metres of a boundary)
  • Uses materials similar in appearance to the existing house
  • Covers less than 50% of the garden space
  • Does not include raised platforms above 300mm or features like first-floor balconies

Note: If you wish to extend beyond 3m, you’ll need to submit a Prior Notification to your local authority. They may consult your neighbours, and any objections could stop the build.

When Planning Permission Is Required

You’ll need full planning permission if:

  • Your property is in a conservation area, AONB, or has an Article 4 Direction
  • The veranda negatively affects neighbour privacy or light
  • It’s part of a listed building
  • You exceed size or height limits
  • You’re including features not covered under PDR, like raised decks or platforms

Even if planning permission isn’t required, the structure must comply with Building Regulations — particularly for foundations, drainage, glazing, and electrics. If you’re unsure, applying for a Certificate of Lawful Development is a smart move.
