Planning Permission for Attic Conversions

Transform unused roof space safely, compliantly, and with confidence.

Converting your attic is one of the most effective ways to add valuable living space without increasing your home’s footprint. Whether you’re creating a new bedroom, office, or playroom, it’s important to understand the planning rules and ensure the project meets all requirements.

At Property Health Check, our surveyors and structural engineers assess your property’s suitability for conversion, guide you through the planning requirements, and help ensure your project complies with building regulations.

Do You Need Planning Permission for an Attic Conversion?

While many attic conversions proceed under the exempted development rules, some projects will require a formal planning application depending on the scale and alterations involved.

Attic conversions that may not require planning permission

  • Internal conversions which do not alter the shape or height of the existing roof.
  • Conversions that do not include dormer windows on the front elevation facing a public road.
  • Works which maintain the property’s external appearance consistent with exempt criteria.

Attic conversions that will likely require planning permission

  • Any dormer extension that changes the roof profile or increases ridge/hip height.
  • Insertions of windows or roof-lights in the front-elevation roof slope (facing the public road).
  • Conversions that cross the exempt development thresholds (either volume, head-height, external changes, or location).
  • Projects involving a protected structure or located in a conservation area.

 

Our team will review your plans, check your exempt status, and advise whether permission is needed.
