Extending Your Home in the Broads: Planning in Wroxham, Hoveton and Stalham

Homes around Wroxham, Hoveton, Stalham, Horning and Ludham sit in one of the most protected landscapes in the country. Many are close to the water, which is exactly why people love living there — and why extending them comes with a few extra checks.

None of this means you can’t extend. It means it pays to know the rules before the drawings are done. Here is a plain guide.

Who deals with your planning application?

The Broads has the same level of protection as a National Park, and inside its boundary the Broads Authority is the planning authority, not the district council. The boundary follows the rivers and broads closely, so it can split a village: some homes in Hoveton and Wroxham are inside it and their neighbours a street away are not.

• Inside the Broads area: apply to the Broads Authority.
• Outside it: Wroxham applications go to Broadland District Council; Hoveton and Stalham go to North Norfolk District Council.
• Building Regulations are separate in every case. They are handled by the district council’s Building Control or a registered building control approver, not the Broads Authority.

Not sure which side of the line you are on? The Broads Authority’s duty planner (01603 610734, weekdays 9am to 1pm) can help with general questions, or your district council can confirm.

What you can build without planning permission

The Broads is classed as “Article 2(3) land” — the same group as National Parks, the Norfolk Coast National Landscape and conservation areas. Permitted development rights (the work you can do without a planning application) are tighter here:

• Side extensions always need planning permission.
• Rear extensions of more than one storey need planning permission.
• Cladding any part of the outside in stone, render, timber, plastic or tiles is not permitted development.
• The larger single-storey rear extension scheme (up to 6 or 8 metres with prior approval) does not apply. The standard limits of 3 metres for an attached house or 4 metres for a detached one still do.
• Roof extensions such as dormers, and adding a storey, are not permitted development.

The Broads Authority also has more than 20 Article 4 directions that remove some rights in particular areas, and planning conditions on your own home may have removed others. If you plan to rely on permitted development, a lawful development certificate from the planning authority gives you written confirmation — useful when you come to sell.

Flood risk

Many riverside homes in the Broads are in Environment Agency Flood Zone 2 or 3. You can check yours on the government’s “Flood map for planning” service. If any part of your site is in one of these zones, a planning application for an extension needs flood risk information. The Environment Agency’s standing advice for householder extensions asks for:

• Floor levels no lower than the existing floor levels, or 300 mm above the estimated flood level.
• A plan showing floor levels and flood levels, measured from Ordnance Datum (height above sea level).
• Flood resistance and resilience measures where needed, such as raised electrics and materials that recover after a flood.

Applications without satisfactory flood information may be refused, so it is worth getting this right first time. Ground near the water can also be soft, which can mean deeper or specially designed foundations — see our post on extension foundations in Norfolk.

Design: fitting into the landscape

Planners in the Broads look closely at the size of an extension, the materials and how it sits in views from the water and the riverbank. Extensions that are clearly smaller than the original house, and that use materials already found nearby — such as red brick, clay pantiles and dark timber boarding — usually have a better chance. Large areas of glazing facing the river can get extra attention.

Some areas are also conservation areas, such as Stalham Staithe, and many older buildings are listed — see our page on listed buildings. Near water, an ecology survey may be asked for, for example if the roof of the house is being altered and bats could be present.

The Broads Authority decides applications using its Local Plan adopted in 2019. A new Local Plan was submitted for examination in February 2026, with hearings due in February 2027, so the 2019 plan still applies for now.

Get advice before you apply

For anything beyond a simple project, pre-application advice is well worth it. Since 1 April 2026 the Broads Authority charges £180 (including VAT) for householder advice, with a written reply within 20 working days. A site visit costs an extra £300. Broadland and North Norfolk councils offer their own advice services too.

After that, councils aim to decide most householder applications within 8 weeks. Allow extra time for surveys, flood information and any changes the planners ask for. Our guide to planning permission vs Building Regulations explains how the two approvals fit together, and if you share a wall with a neighbour, see our practical guide to the Party Wall Act.

Frequently asked questions

How do I know if my home is in the Broads Authority area?

The boundary follows the rivers closely, so being near the water doesn’t always mean you are inside it. The Broads Authority’s duty planner or your district council can confirm for your address.

Can I build a rear extension in the Broads without planning permission?

Possibly, if it is single storey and within the standard limits (3 metres for an attached house, 4 metres for a detached one), with no cladding and no planning conditions removing your rights. A lawful development certificate confirms it in writing.

Do I need a flood risk assessment for an extension?

If any part of your site is in Flood Zone 2 or 3, yes — your planning application needs flood risk information, including floor levels and any flood resilience measures.
