Hardway householder planning by the numbers

Gosport Borough Council granted 97% of the householder planning decisions it made in its latest published year — 10 points above the 87% England-wide householder average. Hardway contains Hardway, Priddy's Hard conservation areas (Hardway designated 1985), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant interwar (1918–1939) housing stock sets the design brief on most streets.

Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. In conservation areas such as Hardway and Priddy's Hard those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Hardway is determined against an 8-week statutory target.

Hardway (conservation area designated in 1985) and Priddy's Hard (conservation area designated in 1990) — these are the Hardway pockets our drawings cover most. Heritage designations here include Hardway and Priddy's Hard. Gosport Borough Council weighs each proposal against the adopted Gosport local plan and Gosport Borough Council's design guidance for householder work, where the 2,520 homes here are 37% 2000-2008, 29% 1930-1939, 7% 1973-1982, which is what sets the realistic roof and rear-projection options. On roofs the borough is trussed-rafter roofs typical of 2000s building and hipped roofs with shallow pitches typical of 1930s building, over 2000s houses and apartments (37% of 2,520 homes), 1930s semi-detached and detached houses (29%) and 1970s and early-1980s houses (7%).

What actually constrains a project in Hardway

Hardway's designated heritage is specific, and it is the first thing we check against your address: Hardway (conservation area designated in 1985) and Priddy's Hard (conservation area designated in 1990). Inside those boundaries permitted development is curtailed and Gosport Borough Council assesses materials, window detail and roof form against the area's own appraisal, so a scheme that would be waved through two streets away can need a full application here.

No Article 4 direction is recorded for Gosport Borough Council, but Hardway's 2 conservation areas still limit permitted development on those streets.

On stock, Hardway is 2000s houses and apartments (37% of 2,520 homes), 1930s semi-detached and detached houses (29%) and 1970s and early-1980s houses (7%) — which is why trussed-rafter roofs typical of 2000s building and hipped roofs with shallow pitches typical of 1930s building govern what a loft or rear projection can realistically be. Gosport Borough Council decided 117 householder applications in the latest published year and granted 97%, with 76% issued inside the eight-week target. Those are the numbers our drawings are prepared against.

The full build-period split for Hardway runs pre-1900 6% (140 homes), 1900-1918 3% (70 homes), 1919-1929 0% (10 homes), 1930-1939 29% (740 homes), 1945-1954 5% (130 homes), 1955-1964 4% (100 homes), 1965-1972 1% (30 homes), 1973-1982 7% (170 homes), 1983-1992 4% (100 homes), 1993-1999 0% (10 homes) and 2000-2008 37% (920 homes). That distribution is why pre-1900 detailing dominates the drawings here, and it is measured from council-tax records rather than assumed from the street name.

Gosport Borough Council also decides for Anglesey, Forton, Harbourside & Town, Lee West and Leesland & Newtown, so a decision in Hardway sits inside a wider pattern of decisions we track across the same authority — useful when an officer cites a precedent from the next area over.

How the prior approval route works in Hardway

The ordinary Class A limits stop a single-storey rear extension at 3 metres on an attached house and 4 on a detached one. The larger home extension scheme doubles both, on condition that the council is told first. That notification is not an application for permission — the council cannot refuse on design, materials or policy grounds. It can only consider the effect on the amenity of adjoining premises, and only if a neighbour actually objects during the 21-day consultation.

The other conditions still apply and are strict: single storey only, no higher than 4 metres, eaves no higher than the existing eaves, and no more than half the land around the original house covered. It is not available on designated land, so a house in a conservation area such as Hardway and Priddy's Hard cannot use it at all. Materials must be similar to the existing house, and the extension must not include a veranda, balcony or raised platform.

Hardway is largely 2000s houses and apartments (37% of 2,520 homes), 1930s semi-detached and detached houses (29%) and 1970s and early-1980s houses (7%). Hardway contains Hardway, Priddy's Hard conservation areas (Hardway designated 1985), so materials, fenestration and roof form are assessed against the appraisal, which matters here because an objecting neighbour puts amenity squarely in front of a case officer. No Article 4 direction is recorded for Gosport Borough Council, but Hardway's 2 conservation areas still limit permitted development on those streets.

Does your Hardway extension qualify for prior approval?

The scheme is available where all of these hold. Fail any one and it is a full application to Gosport Borough Council instead:

  • The extension is single storey and rear-facing
  • It projects no more than 6 metres on a terraced or semi-detached house, or 8 metres on a detached house
  • It is no more than 4 metres high, with eaves no higher than the existing eaves
  • The property is a house, not a flat or maisonette
  • The property is not on designated land — the scheme is unavailable in conservation areas such as Hardway and Priddy's Hard
  • No more than half the land around the original house is covered by buildings
  • The materials are similar in appearance to the existing house
  • You notify the council BEFORE building — retrospective use of the scheme is not possible

Hardway householder decisions — live from council data

Below is Gosport Borough Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Gosport Borough Council granted 97% of its householder applications in the year to 31 March 2026, and Hardway shapes what is approved here. Prior approval turns on neighbour amenity alone, so the drawings that matter are the ones showing the relationship to the boundary.

What gets through prior approval in Hardway

Across Hardway and Priddy's Hard, the notifications that clear without objection are the ones that treat the neighbour as the audience. We show the extension in section against the boundary, demonstrate the 45-degree daylight relationship to the nearest habitable window, and where the plot is tight we taper the depth away from the boundary rather than running the full 6 metres to the fence.

The 2,520 homes here are 37% 2000-2008, 29% 1930-1939, 7% 1973-1982, which is what sets the realistic roof and rear-projection options. Where an objection does arrive, the council's assessment is narrow: loss of light, outlook and overbearing effect on the adjoining property, nothing else. A pack that has already answered those three points on the drawings usually survives an objection, whereas one that leaves them to the officer's imagination usually does not.

Four steps to prior approval in Hardway

A process built around the 21-day consultation, which is where these schemes are won or lost.

  1. 1

    Free eligibility check

    Send us your Hardway postcode and house type. We confirm whether the property is on designated land, whether the scheme is available, and what depth you can realistically take.

  2. 2

    Measured survey

    We measure the original rear wall, eaves height, boundary distances and the neighbouring windows that the amenity assessment will turn on.

  3. 3

    Notification pack

    We draw the extension to the 6m or 8m limit with the boundary relationship shown in section, and prepare the written description and adjoining-owner details Gosport Borough Council needs to start the consultation.

  4. 4

    Consultation & follow-through

    We submit, track the 21-day consultation and the 42-day determination, respond to any objection on amenity grounds, and revise free until the decision.

Frequently asked questions

How deep can a rear extension be in Hardway without planning permission?

Three metres on a terraced or semi-detached house and four on a detached one under ordinary permitted development. Under the larger home extension prior approval scheme those double to six and eight metres, provided you notify Gosport Borough Council before starting and the conditions on height, materials and land coverage are met. The scheme is not available on designated land. This applies to your Hardway address specifically.

What is prior approval for a larger home extension in Hardway?

It is a notification, not an application for permission. You tell Gosport Borough Council what you intend to build, it writes to the adjoining owners, and they have 21 days to object. If nobody objects, you may build. If someone does, the council assesses the effect on the amenity of adjoining premises and must decide within 42 days. Design and policy are not in scope. This applies to your Hardway address specifically.

What happens if my neighbour objects in Hardway?

The council then considers the impact on the amenity of the adjoining property — loss of light, loss of outlook, and overbearing effect — and nothing else. It cannot refuse because it dislikes the design or the materials. We prepare the drawings so those three questions are already answered in section and on the site plan, which is what usually carries an objected scheme through. This applies to your Hardway address specifically. Gosport Borough Council is the decision-maker.

Can I use prior approval in a Hardway conservation area?

No. The larger home extension scheme is unavailable on designated land, which includes conservation areas such as Hardway and Priddy's Hard, national landscapes, national parks and world heritage sites. On those properties the ordinary 3-metre and 4-metre limits apply, and anything deeper needs a full householder application to Gosport Borough Council.

How long does prior approval take in Hardway?

Twenty-one days for the neighbour consultation, and a maximum of 42 days from a valid submission for the council to determine it. If the council does not respond within 42 days you may proceed as notified. That deadline is the scheme's real advantage over a full application, and it is why validation completeness matters so much. This applies to your Hardway address specifically. Gosport Borough Council is the decision-maker.

Do I still need building regulations approval in Hardway?

Yes — always. Prior approval deals only with the planning position. A 6-metre rear extension still needs building control approval for foundations, structure, drainage, thermal performance and fire safety, and the beam over the opening into the existing house needs designing and calculating. We prepare both sets so the notified scheme is the buildable one. This applies to your Hardway address specifically. Gosport Borough Council is the decision-maker.

How much do prior approval drawings in Hardway cost?

We quote each Hardway scheme individually, because plot shape and the boundary relationship drive the work, and send a fixed, no-obligation quote within one working day. It covers the notification pack and free revisions until Gosport Borough Council determines it. Call 020 7864 7245 to start.
