Attic Conversion Planning Service

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.

What’s Involved

Our attic conversion planning service is delivered in two clear stages:

  • Step 1 – Preparation of Planning Drawings

    We prepare all planning drawings required for your home extension, based on a review of your property and the proposed works. To ensure consistency, accuracy and compliance all planning drawings for this service are prepared by our team. We do not accept drawings prepared by a third party.

  • Step 2 – Planning Application

    Once the drawings are complete, we will advise on whether planning permission is required. Where appropriate, we can proceed with submitting the planning application on your behalf. If planning permission is not required, or if you decide not to proceed, we will clearly outline the next step.

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.

 

Retention & Outline Planning

Not all projects fall under a standard home extension planning application.

Retention Planning Permission
If works have already been carried out without planning permission, a retention application may be required to regularise the development. Click here for further information. Retention Planning Permission

Outline planning permission
