What Can I Build Without Planning Permission in the UK?
Not all building work requires planning permission. Certain developments fall under "permitted development rights," allowing you to make changes without formal approval. Knowing these exceptions can save time and money.
Common Permitted Developments
Single-storey rear extensions: Usually up to 3 metres for terraced houses and 4 metres for detached homes.
Loft conversions: Provided they do not exceed certain height limits and do not extend beyond the existing roof slope.
Porches: Small porches under 3 square metres.
Outbuildings: Sheds, garages, or greenhouses within certain size limits and not used as separate living accommodation.
Solar panels: Installation on roofs without exceeding height restrictions.
However, these rights can be restricted in conservation areas, national parks, or if your property is listed. Always check with your local council or consult experts like AGA Associates to confirm what applies to your property.

How to Prepare a Successful Planning Application
Preparation is key to securing planning permission. A well-prepared application reduces the risk of refusal and speeds up the process.
1. Research Local Planning Policies
Each London borough has its own planning framework. Review the local development plan and supplementary planning documents. These outline what is acceptable in your area regarding design, scale, and use.
2. Engage with Neighbours and Stakeholders
Early engagement can prevent objections later. Inform neighbours about your plans and address their concerns. This shows goodwill and can lead to smoother approval.
3. Hire Experienced Professionals
Working with architects and planning consultants who understand London’s planning system is invaluable.

Navigating the Challenges of Planning Permission in London
London’s planning system can be challenging due to high demand, conservation areas, and complex regulations. Here are some common challenges and how to overcome them:

If your property is in a conservation area or is listed, you face stricter controls. You may need listed building consent in addition to planning permission. AGA Associates has extensive experience working with heritage properties and can guide you through these additional requirements.
