Do I Need Planning Permission for a Glass Extension in the UK?

Glass extensions are a fantastic way to transform your home—but before you start dreaming of panoramic windows and sun-soaked lounges, it’s important to understand if you need planning permission. Let’s break it down.

Skycube is is a modular glass veranda system designed to offer a minimalist, floating-glass aesthetic with uncompromised strength and stability. It’s the ultimate choice for expansive outdoor living areas.

When Planning Permission Is Not Required (Permitted Development)

  • The extension doesn’t exceed half the width of the original house
  • It doesn’t project more than 4m (detached) or 3m (semi-detached/terraced) from the rear wall
  • The structure is no higher than 4m (with eaves max 3m near boundary)
  • It’s built at ground level
  • It’s not built on designated land (AONB, conservation areas, etc.)

When You Do Need It:

  • If your home is listed or in a protected area
  • If you want a roof terrace, balcony, or raised platform
  • If the extension affects neighbouring privacy or light access
  • If you're altering the main façade facing the street

Glass Extension Considerations:
While products like Luma Shade and SkyCube are often classed as pergolas or verandas (and may not need planning), full glass rooms like Aurelia might.

Conclusion:
Always check with your local planning authority, or let our team help guide you through the process to ensure a smooth and compliant installation.
