Planning
Planning your home project
Planning any project, whether it's a home improvement, new build, or renovation, requires careful consideration of the rules and regulations that may apply. Understanding the permissions and approvals needed is a crucial first step to ensure your plans run smoothly, avoid unexpected delays, and comply with legal requirements. This page provides essential guidance to help you navigate the process, empowering you to move forward with confidence and clarity.
Introduction to Planning and Its Types
Planning is an essential aspect of any home improvement or construction project. Whether you're looking to extend your living space, convert unused areas, or undertake major structural changes, understanding the planning process is key to ensuring your project is successful and compliant with local regulations. Planning not only covers obtaining permissions but also ensures that your project aligns with safety standards, environmental considerations, and aesthetic requirements.
There are several types of planning permissions that may apply depending on the scope and nature of your project. Below, we outline the most common types to help you understand what’s involved and how they differ. Detailed sections for each will provide specific guidance to simplify your planning journey.
Types of planning projects
House Extension
Whether you're adding a single-storey extension or a larger multi-storey addition, extensions often fall under Permitted Development or require Planning Permission, depending on size, location, and design.
Loft conversion
Transforming your loft into a functional living space can significantly increase your home's value and usability. Planning requirements vary based on factors such as roof height, dormer additions, and external alterations.
Basement Conversion
Creating a basement space, whether for storage or living, often involves more complex planning considerations. These include structural safety, drainage systems, and the impact on neighboring properties.
Permitted development vs Planning permission for House Exension
When planning a house extension in the UK, one of the most common questions homeowners face is whether their project falls under Permitted Development rights or requires Planning Permission. Knowing the distinction between the two is essential to ensure your project complies with local regulations and avoids unnecessary delays or fines.
This guide provides a clear comparison of Permitted Development and Planning Permission, covering key aspects such as size limitations, height restrictions, and the application process. Whether you're planning a small single-storey extension or a more ambitious project, understanding these rules can help streamline your plans and prevent legal complications.
Explore the table below to determine whether your house extension qualifies as Permitted Development or requires Planning Permission. By knowing the specifics, you can save time, reduce costs, and achieve a smoother approval process.
Aspect | Permited | Planning |
|---|---|---|
Definition | Rights allowing certain works to be carried out without needing formal permission from the local authority. | Formal approval required from the local planning authority for works outside permitted development rights. |
Scope | Applies to minor extensions and alterations that comply with strict conditions and limitations. | Covers larger or more complex projects that fall outside the scope of permitted development. |
Size Limitations | - Single-storey rear extensions up to 3m for attached houses and 4m for detached houses.- Two-storey rear extensions limited to 3m in depth and must be at least 7m from the rear boundary. | Extensions exceeding the above limits require planning permission. |
Height Restrictions | - Single-storey extensions must not exceed 4m in height.
- Extensions must not be taller than the original house.
| Taller extensions or those above 4m typically require planning permission. |
Location | Extensions must not extend beyond the principal elevation (front of the house) or towards a public highway. | No strict restrictions based on the highway, but the location is subject to approval during the application process. |
Building Coverage | Must not exceed 50% of the land surrounding the original house. | Larger coverage may be allowed but is subject to approval. |
Protected Areas | Does not apply in designated areas (e.g., conservation areas, national parks) without additional permissions. | Can apply in designated areas but typically faces stricter scrutiny. |
Application Process | No application required, but prior approval might be needed for certain larger extensions (e.g., up to 6m or 8m depth under the Neighbour Consultation Scheme). | Formal application required, including plans, drawings, and fees. |
Cost | Generally free, except for cases requiring prior approval (£96 fee in most cases). | Application fees apply (e.g., £206 for a householder planning application in England). |
Timeframe | Typically quicker, with prior approval decisions taking around 6-8 weeks. | Decisions usually take 8-10 weeks but can take longer if the project is complex. |
Conditions and Limitations | Strict conditions (e.g., materials must match the existing house, no balconies or raised platforms). | Greater flexibility, but proposals are assessed for impact on neighbors, environment, and compliance with local policies. |
Enforcement | Local authorities can take action if development exceeds permitted rights. | Work without permission can result in enforcement action, including fines or a requirement to undo the work. |
