Planning permission does not mean you’re ready to start building.
Planning approval focuses on how your extension looks — things like size, height and external appearance.
Building Regulations focus on how it’s built — structure, safety and compliance.
Confusing the two is one of the most common causes of delays on residential projects.
If you’re planning an extension in the West Midlands, make sure both approvals are in place before work starts on site.
