Understanding the Importance of Planning Permission
Planning permission is a legal requirement to build a new house in the UK. It ensures that developments are safe, suitable, and in keeping with the area around them. It also helps protect the local environment, road access, and neighboring properties.
Starting a build without permission could force you to undo your work. It’s always best to secure the right approvals before any construction begins.
In Norfolk and Suffolk, local councils like Broadland, South Norfolk, West Suffolk, and East Suffolk have slightly different planning policies. This is especially true in conservation areas, coastal zones, or the Norfolk Broads. The good news is that the general steps for securing permission are the same regardless of where you are.
1. Permission in Principle: A Low-Risk Starting Point
Permission in Principle (PiP) is the simplest type of planning application. It's often used to explore the potential of a plot before investing significant time or money.
What Does It Involve?
You submit a basic form that outlines:
The location of the site
What type of development you’re considering (for example, a single home)
The size of the site
There's no need for full designs or technical drawings at this early stage.
When Is It Useful?
PiP is ideal if you’re just starting out. Perhaps you've spotted a patch of land on the edge of a village in South Norfolk or in a quiet part of Mid Suffolk. You might be wondering if a home would be permitted there.
This approach is a cost-effective way to check if the principle of development would be supported by the council.
What Happens Next?
If PiP is approved, you’ll still need to follow it up with a Technical Details Consent application to fill in all the missing pieces. However, getting PiP first gives you the confidence to move ahead.
2. Outline Planning Permission: Sketching Out the Big Picture
Outline planning permission goes a step further than PiP. It’s like showing a sketch of your idea and asking the council for feedback before committing to the full design.
What Does It Include?
This type of application usually covers:
The location of the building
Its size and shape
How access to the site will work
Basic drainage and infrastructure considerations
You don’t have to decide on specifics like window positions or building materials at this point. Those details can come later under “reserved matters”.
When Is It Useful?
Outline permission is great if you want to test the waters while keeping things flexible. Maybe you’re planning a self-build in a conservation village in North Norfolk or aiming to maximise a narrow plot in East Suffolk. This route allows you to confirm whether a home is likely to be supported before developing detailed architectural drawings.
What Happens After Approval?
If you receive outline permission, you must apply for reserved matters within three years. This is where you provide the full details necessary to get the green light to build.
3. Full Planning Permission: Time to Get Specific
If you have a clear idea of what you want to build and are ready to start, full planning permission is what you need.
What Does It Involve?
This application is much more detailed and includes:
Site plans
Floor plans and elevations
Roof design
External materials
Access and parking
Drainage and landscaping
Typically, you’ll need to work with a local architectural designer, architectural technologist, or architect to pull these materials together.
When Is It the Best Option?
Full planning permission is essential if you're confident in your design and ready to progress. It is particularly beneficial in locations where detail matters, such as near the Broads National Park, along the Suffolk Coast, or in market towns with stricter design rules.
It’s also required if you're changing the use of a building. This includes, for example, converting a barn under Class Q regulations or replacing an existing dwelling.
How Long Is It Valid?
Once granted, you normally have three years to begin construction.
4. Replacement Dwellings: A New Home on the Same Plot
Sometimes the best way to build a new home is to start with an old one. In planning terms, a replacement dwelling refers to knocking down an existing house and constructing a new one in its place.
What Are the Benefits?
In many areas of Norfolk and Suffolk, obtaining approval for a replacement home is often easier than for a new one on undeveloped land. This is because there is already a precedent for a home on that site.
You can also avoid some of the tricky countryside development rules if your replacement is similar in scale and location to the original structure.
What Are the Rules?
Councils usually expect:
The new house to be on or near the footprint of the old one
A similar size or slightly larger (within reason)
A design that suits the local character
If you’ve found a tired 1950s bungalow near Diss or a damp cottage outside Woodbridge, this could be a great opportunity to build something modern, efficient, and perfectly suited to your needs.
Helpful Tips for Planning in Norfolk and Suffolk
Here are some essential considerations for your self-build journey:
Seek Professional Advice: Getting professional advice on the feasibility of a plot first will help you move forward efficiently.
Pre-Application Advice: Most councils offer pre-application advice. Early feedback is worth the small fee, especially in conservation areas or near protected countryside.
Design Integration: Homes that align well with their surroundings are more likely to gain approval. This doesn’t mean mimicking old styles, but incorporating local materials and proportions can significantly help.
Eco-Friendly Homes: Planning departments increasingly encourage eco-friendly homes with low energy use, good insulation, and renewable technologies.
Budget for Costs: Planning fees, surveys, reports (like ecology or drainage), and professional drawings can add up. Ensure you’ve accounted for them in your budget. If you’re interested in learning more about your self build costs, check out our in-depth article on costs.
Creating a self-built home in Norfolk or Suffolk offers a distinctive opportunity to design a place that meets your lifestyle and complements your surroundings. From barn conversions in the countryside to innovative new builds in towns and villages, it allows you to live sustainably and thoughtfully.
Planning permission may seem challenging, but with the right knowledge and support, it becomes a manageable step-by-step process. Start small, seek advice, and take your time.

How long does it take to get planning permission?
Most councils aim to decide straightforward applications within 8-12 weeks. More complex applications or those in sensitive areas may take longer.
Can I appeal if my application is rejected?
Yes, you can appeal to the Planning Inspectorate within six months of the decision. However, it's often more effective to address the council's concerns and submit a revised application.
Do I need planning permission for small outbuildings?
Some outbuildings fall under 'permitted development' rights and don't need planning permission if they meet certain criteria. However, these rights may be restricted in conservation areas or Areas of Outstanding Natural Beauty.
Can I build on agricultural land?
Converting agricultural land for residential use typically requires planning permission and a change of use application. This can be challenging but is possible with the right approach and justification.
What surveys might I need for my application?
Common surveys include ecological surveys (especially for bat and newt habitats), tree surveys, flood risk assessments, heritage statements for historic areas, and sometimes traffic or noise assessments.
How do I find a good architectural designer who understands local planning rules?
Local architectural practices often have established relationships with planning consultants and experience with local planning officers, and understand the nuances of local policies.
Can I live on-site during construction?
You typically need temporary planning permission to live on-site during construction. This is considered on a case-by-case basis and usually requires justification for why you need to be on-site.
What is a Design and Access Statement?
How strictly do I need to follow approved plans once permission is granted?
Very strictly. Any significant changes need approval through an amendment application. Building something substantially different from approved plans could result in enforcement action.
