Understanding the Planning Landscape in Hampshire
Getting planning permission in Hampshire means applying to the correct local planning authority, paying the right fee, and complying with local and national planning policy. There is no county-wide planning department: 11 district and borough councils each handle their own area, plus two national park authorities.
That fragmentation is where homeowners stumble. You apply to Winchester, Basingstoke and Deane, East Hampshire, or the New Forest National Park Authority, not to "Hampshire". Get it wrong and your application is invalidated and weeks are lost.
Which Local Planning Authority Handles Your Application?
Your local planning authority is the district, borough, or national park council covering your property's address. Finding it takes two minutes and saves months.
Use the government's Planning Portal's authority finder to enter your postcode. The tool returns the exact council handling your area. For most Hampshire homeowners, that's one of the district councils. If your property sits inside the New Forest or South Downs National Park, the national park authority decides instead, and its policies are stricter.
SD Architecture confirms the authority before any design work begins, preventing the most common early mistake of drawing plans for the wrong policy framework.
Permitted Development Rights Hampshire: What You Can Build Without Approval
Permitted development rights let certain householder projects proceed without a full planning application. In Hampshire the headline allowances follow national rules (the Town and Country Planning (General Permitted Development) (England) Order 2015), but local constraints frequently remove or narrow them, where most homeowners get caught out.
The standard allowances for a detached house include:
Rear extensions: up to 4 metres deep for a single-storey extension, or 3 metres for a two-storey extension, measured from the original rear wall
Height limits: a single-storey rear extension must not exceed 4 metres in height; a two-storey extension must not exceed the eaves height of the existing house and must not be closer than 7 metres to the rear boundary
Materials: extensions must use materials matching the existing house
Loft conversions: up to 40 cubic metres of additional roof space for a terraced house, 50 cubic metres for any other house
Outbuildings: incidental buildings such as sheds, garages and home offices, subject to height and coverage limits
Porches: up to 3 square metres in footprint and 3 metres in height
These are the national defaults. What matters in Hampshire is what has been removed on top of them.
Article 4 Directions: The Local Override You Must Check
An Article 4 direction withdraws permitted development rights for a specific area or property type. Where one applies, work that would otherwise be permitted development needs a full planning application.
Hampshire's district and borough councils use Article 4 directions routinely, most commonly to protect:
Conservation areas, where side extensions, front-facing dormers, cladding, and outbuildings are often restricted
Areas of high housing pressure, where councils remove permitted development for changes of use from commercial to residential
Specific streets or character areas, where the cumulative impact of small extensions is a concern
Fitting the national size limits does not mean you are clear. Check your council's Article 4 register alongside its conservation area maps, most councils publish both on their planning pages, and a postcode search takes minutes.
Conservation Areas, National Parks and Listed Buildings
Three constraints in Hampshire override permitted development more often than any others:
Conservation areas. Permitted development is restricted for side extensions, cladding, outbuildings, and roof alterations. Some rights may remain, but they are narrower and the design bar is higher.
National park authorities. Inside the New Forest or South Downs National Park, the national park authority is your local planning authority, with stricter policies than the district councils. Permitted development is more likely to be withdrawn and design guidance more prescriptive.
Listed buildings. Listed building consent is required for almost any alteration affecting the character of a listed building, on top of any planning permission. Permitted development rights do not bypass this.
Watch Out If your property sits in a conservation area, a national park, an Area of Outstanding Natural Beauty, or is a listed building, permitted development rights may be withdrawn entirely. Proceeding without confirmation risks enforcement action and a requirement to undo completed work.
How to Confirm Your Position Before You Build
Before you instruct a builder or order materials, work through this checklist:
Find your local planning authority using your postcode on the Planning Portal's authority finder
Check the Article 4 register on your council's planning pages for your address or street
Check conservation area maps on the same council site
Check listed building status using the Historic England's National Heritage List
Confirm national park status if you are near the New Forest or South Downs boundaries
Apply for a lawful development certificate if you want written proof that your project is permitted development, this is optional but valuable if you plan to sell
A lawful development certificate is the only way to get a formal council decision confirming your project does not need planning permission. It is not planning permission and does not expire in the same way, but it removes the risk of enforcement later.
Pro Tip If you are unsure whether permitted development applies, a lawful development certificate application is usually cheaper and faster than a full planning application, and it gives you a paper trail if a neighbour or a future buyer raises questions.
When Permitted Development Is Not Enough
If your project exceeds the national limits, or an Article 4 direction or conservation area designation removes your rights, you need a full householder planning application, with higher design and documentation requirements and a longer decision timeline.
How to Submit a Planning Application: A Step-by-Step Process
Submitting a planning application means completing the correct form, uploading supporting documents, and paying the fee through the Planning Portal or your council's system. Most householder applications are submitted online.
Follow these steps:
Confirm your local planning authority using your postcode
Check permitted development rights and any Article 4 directions affecting your property
Commission accurate drawings and a site plan at the correct scale
Seek pre-application advice from your council for anything unusual
Complete the application form on the Planning Portal
Upload supporting documents, including the location plan, block plan, and existing and proposed elevations
Pay the fee and submit
Respond to any consultee queries during the statutory period
Pre-Application Advice and Supporting Documents
Pre-application advice is a paid service where a planning officer reviews your proposal informally before submission. It's optional but valuable for complex sites.
The documents most applications need include a location plan, a block plan, existing and proposed floor plans and elevations, and a design and access statement for larger schemes. Missing documents are a leading cause of delay.
Pro Tip Request pre-application advice in writing and keep the response. If your application is later refused on a point the officer raised no objection to, that correspondence strengthens any appeal.
How Long Does Planning Permission Take in 2026?
Most householder applications are decided within the statutory eight weeks; full planning applications typically take 13 weeks, and complex schemes longer.
The clock starts at validation, not submission. Missing documents stall validation and reset the timeline, so treat document completeness as the real deadline.
Application Type | Statutory Decision Period | Typical Hampshire Timeline |
Householder application | 8 weeks | 8-10 weeks |
Full planning application | 13 weeks | 13-16 weeks |
Listed building consent | 8 weeks | 8-12 weeks |
Pre-application advice | No statutory limit | 4-8 weeks |
Planning Application Fees UK: What You Need to Budget For
Planning application fees in the UK are set nationally and updated annually. The fee depends on application type, not project value or house size, and your local planning authority cannot vary it, it is the same whether you apply to Winchester, Basingstoke and Deane, or the New Forest National Park Authority.
The fees most Hampshire homeowners encounter are:
Application Type | Typical Fee (England) |
Householder application (extensions, loft conversions, outbuildings) | Around £258 |
Full planning application for a single new dwelling | Around £578 per dwelling |
Listed building consent | No fee |
Lawful development certificate (existing use) | Around £258 |
Lawful development certificate (proposed use) | Around £129 |
Pre-application advice | Varies by council, often £100-£500+ |
These figures are indicative and change when government updates the fee schedule. Always check the current figures on the government's planning fee schedule and your council's own planning pages before you budget. Some councils also charge a separate fee for pre-application advice that scales with the complexity of the proposal.
The Costs Beyond the Application Fee
The application fee is rarely the largest line in a planning budget. Most homeowners are surprised by the professional and statutory costs alongside it:
Architectural drawings and site plans. A householder application typically needs a location plan, a block plan, existing and proposed floor plans, and existing and proposed elevations. Expect to pay for these unless you draw them yourself.
Design and access statement. Required for larger schemes and most applications in conservation areas or national parks.
Heritage statement. Required for listed buildings and often for properties in conservation areas.
Tree survey and arboricultural report. Common where protected trees are nearby.
Flood risk assessment. Required for sites in Flood Zones 2 or 3, which affects parts of Hampshire.
Drainage and ecology reports. Increasingly requested for larger schemes and sites near protected habitats.
Building regulations approval. Separate from planning permission and charged separately by your building control body.
Structural engineering. Needed for most extensions, loft conversions, and any work affecting load-bearing elements.
Key Takeaway Application fees are only one line in your budget. Building control, structural engineering, and specialist reports frequently surprise first-time self-builders, so ask your architect to flag every statutory cost upfront before you commit to a design.
How Fees Interact With the Application Process
A few practical points catch people out:
Fees are not refunded if your application is refused. You pay again if you resubmit a revised scheme, unless your council offers a free resubmission window (some do, within 12 months, for refused householder applications, check your council's policy).
Invalid applications are refunded, but time is lost. If you submit to the wrong authority or with missing documents, the application is invalidated and the fee returned, but you restart the clock.
Pre-application advice is not deducted from the application fee. It is a separate charge, and it does not guarantee approval.
National park authorities may charge the same national fees but apply stricter policies, so the cost of getting the design right first time is higher in terms of professional input.
A Realistic Budget Approach
Rather than budgeting around the application fee alone, work backwards from the total statutory and professional cost of reaching a decision. For a typical householder extension in Hampshire, the planning stage alone, drawings, reports, pre-application advice where used, and the fee, commonly runs into four figures before any building work is priced. For a self-build or a scheme in a conservation area or national park, professional input is higher again.
The single biggest saving is getting the application right first time. A refused application costs you the fee, the professional time, and months of delay, and you pay most of it again on resubmission.
Common Reasons for Refusal and How to Avoid Them
Most refusals come down to a handful of recurring problems: poor design ignoring local character, overlooking and loss of privacy, inadequate parking, drainage concerns, and insufficient supporting information.
The fix is almost always front-loaded. Review your council's local plan and design guidance before drawing anything. Match materials and scale to neighbouring properties. Address drainage and access in the application itself rather than leaving officers to assume the worst.
Where a refusal happens, you have a right of appeal to the Planning Inspectorate, but appeals take months. Getting it right first time is faster and cheaper.
Hampshire's fragmented planning landscape rewards preparation and punishes guesswork. Whether you're extending, converting a loft, or self-building, the right drawings, documents, and authority make the difference between approval and refusal. SD Architecture handles the full process for homeowners across the region, from concept and planning applications through building regulations and site supervision.

Frequently Asked Questions
Can I apply for planning permission myself or do I need an architect?
You can submit a planning application yourself. However, an architect ensures your drawings meet local planning policy and building regulations. Many homeowners find professional help reduces the risk of refusal and saves time. For complex projects like extensions or self-builds, an architect's expertise often proves essential for a smooth approval.
What size extension can I build without planning permission?
Under permitted development rights, you can typically extend up to 3 metres for a terraced house, 4 metres for a semi-detached, or 8 metres for a detached property, subject to height limits and material considerations. However, conservation areas and listed buildings have stricter rules. Always check with your local planning authority before starting work.
How long does the planning permission process take from start to finish?
The statutory period for a householder application is 8 weeks, while full planning applications take 13 weeks. In practice, timelines vary based on local planning authority workloads and the need for pre-application advice. Factoring in drawing preparation and consultation, most projects take 3 to 6 months from concept to decision notice.
How much does it cost to get full planning permission?
Planning application fees UK vary by project type. As of 2026, a householder application typically costs around £258, while full planning for a new dwelling can exceed £500. Additional costs include architectural drawings, site plans, and building regulations. SD Architecture provides transparent quotes upfront.
