You're not alone if you’ve ever dreamed of building your own home. More and more people across Norfolk and Suffolk are turning to self-build to create a home that’s truly their own, designed to fit their lifestyle, values, and surroundings.
But before you can start thinking about layouts, kitchens, or timber cladding, there’s one crucial thing to get right: planning permission. Whether you’ve found the perfect patch of countryside or a plot in a quiet village, understanding which permissions apply and how to approach them is key to a successful project.
This guide breaks it all down in plain English, so you can feel confident taking your next step.
Why Planning Permission Matters
Planning permission is a legal requirement to build a new house in the UK. It’s there to make sure that developments are safe, suitable, and in keeping with the area around them. It also helps protect the local environment, road access, and neighbouring properties.
If you start building without permission, you could be forced to undo the work. It’s always best to get the right approvals before anything begins.
In Norfolk and Suffolk, local councils like Broadland, South Norfolk, West Suffolk, and East Suffolk each have slightly different planning policies, especially in conservation areas, coastal zones, or the Norfolk Broads. The good news is that the general steps for getting permission are the same wherever you are.
1. Permission in Principle: A Low-Risk Starting Point
Permission in Principle (PiP) is the simplest type of planning application and is often used to explore the potential of a plot before committing too much 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 to include full designs or technical drawings at this stage.
When is it useful?
PiP is ideal if you’re just starting out. Maybe you’ve seen a patch of land on the edge of a village in South Norfolk or in a quiet part of Mid Suffolk, and you’re wondering if a home might be allowed there.
It’s 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, which fills in all the missing pieces. But getting PiP first gives you 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 need to decide on things like window positions or building materials yet. Those can come later under “reserved matters”.
When is it useful?
Outline permission is great if you want to test the waters but still keep things flexible. Maybe you’re planning a self-build in a conservation village in North Norfolk or want to make the most of 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 get outline permission, you’ll need to apply for reserved matters within three years. This is where you provide the full detail needed to get the green light to build.
3. Full Planning Permission: Time to Get Specific
If you’ve got a clear idea of what you want to build and you’re ready to get started, then full planning permission is what you’ll 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
You’ll likely need to work with a local architectural designer, architectural technologist or architect to pull these together.
When is it the best option?
Full planning permission is essential if you’re confident in your design and ready to move forward. It’s 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, for example, converting a barn under Class Q regulations (a separate topic) or replacing an existing dwelling, which we’ll cover next.
How long is it valid?
Once granted, you normally have three years to begin construction.
4. Replacement Dwellings: A New Home, Same Plot
Sometimes the best way to build a new home is to start with an old one. In planning terms, a replacement dwelling is when you knock down an existing house and build a new one in its place.
What are the benefits?
In many parts of Norfolk and Suffolk, it’s easier to gain approval for a replacement home than a brand-new one on undeveloped land. This is because there’s already a precedent for a home on the site.
You also avoid some of the trickier countryside development rules if your replacement is similar in scale and location.
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 way to build something modern, efficient, and perfectly suited to you.
Helpful Tips for Planning in Norfolk and Suffolk
Here are some things to keep in mind wherever your plot is:
Get design and planning advice first
Getting professional advice on the feasibility of a plot first will ensure you can make efficient steps forward
Talk to your local planning authority
Most councils offer pre-application advice. Getting early feedback is worth the small fee, especially if you’re in a conservation area or close to protected countryside.
Respect the local character
Homes that fit well with their surroundings are more likely to gain approval. This doesn’t mean copying old styles, but thoughtful use of local materials and proportions helps a lot.
Think about energy and sustainability
Planning departments are increasingly encouraging eco-friendly homes with low energy use, good insulation, and renewable technologies.
Budget for more than just building
Planning fees, surveys, reports (like ecology or drainage), and professional drawings all cost money. Make sure you’ve included them in your budget. Want to know more about your self build costs look at our indepth article on costs to learn more.
