SPD Rules Vs PD Rules for Lofts
Considering loft conversion options: SPD or Permitted Development?
Wondering whether to utilize Permitted Development or follow SPD guidelines for your loft conversion? We can guide you through the advantages and drawbacks, helping you achieve the desired shape and style for your new bedroom or ensuite. Keep in mind that SPD policies may differ across boroughs, making it essential to understand local regulations.
What's the preferred approach for designing your loft conversion?
If you’re considering Permitted Development (PD) for your loft, it offers a straightforward set of guidelines. Summarised from the Planning portal, the key rules include ensuring materials match the original house, limiting volume enlargement, not exceeding the existing roof height, and avoiding extension beyond the existing roof slope on the principal elevation facing a highway. Restrictions also cover features like verandas, balconies, and side-facing windows, emphasising the need for compliance with construction details for a successful loft conversion.
These documents may address various topics, including design guides, development briefs, or issue-based documents, all within the framework of national, regional, and local planning policies.
What distinguishes PD Loft Designs from SPD Loft Designs?
PD (Permitted Development) loft designs typically offer more extensive options, allowing full-width, depth dormers, and rear addition-type (L-Shape) style dormers, potentially accommodating two rooms, within volume limits of 40-50m3. Following PD guidelines can secure a Certificate of Lawfulness at a lower cost and shorter duration (8 weeks, costing £103) compared to a planning application, providing homeowners with more substantial living space.
