Planning a renovation or extension in Hampshire? Then you’re probably wondering:

👉 “Do I need planning permission, building regulations approval — or both?”

Here’s a simple breakdown for homeowners in Hampshire, including advice specific to areas like Romsey, Fordingbridge, and Hartley Wintney.

🏗 Planning Permission vs Building Regulations – What’s the Difference?

Planning Permission
Assesses the external appearance and impact of your project on the local area (e.g. size, height, location).

Building Regulations
Ensure your project is safe, energy-efficient and structurally sound — covering things like electrics, insulation, and drainage.

📝 When You Might Only Need Building Regs (Not Planning):

• Internal layout changes
• Loft conversions under Permitted Development
• Garage conversions
• Replacing windows or re-roofing

Even if planning isn’t needed, you still need building regulations approval.

📄 When You Might Need Both:

• New builds
• Two-storey extensions
• Changes to the roof height or shape
• Projects in conservation areas (e.g. Alresford or Southsea)

Your architect will tell you exactly which approvals apply to your site and project.

🧠 How Your Architect Helps:

• Confirms what permissions are needed
• Prepares and submits the planning application
• Produces detailed construction drawings for Building Control
• Liaises with Hampshire authorities to streamline approvals

✅ Summary:

Most projects in Hampshire need building regulations, whether or not they need planning permission. To avoid fines, delays or costly rework, always consult a local architect — they’ll help you tick every box legally and confidently.
