Planning permission is crucial for ensuring that developments align with local regulations, protect the environment and heritage, and meet community needs. It prevents inappropriate building and development, and mandates that construction complies with local planning and environmental guidelines.
Without planning permission, building work is considered unauthorized and could lead to fines or even demolition of the unauthorized structure.
So, how difficult is it to get planning permission and what do I need to do to get it?
Here is our step by step overview and a guideline of the costs that may be expected.
Step-by-Step Overview
1. Determine If Planning Permission Is Required
Not all extensions require planning permission. You may be exempt if:
- The extension is to the rear of the house
- Total area (including previous extensions) does not exceed 40m²
- Height does not exceed 4m (pitched roof) or 3m (flat roof)
Always confirm with a qualified architect or your local authority.
