What the data says about planning in Hartley Wintney

Hart District Council granted 86% of the householder planning decisions it made in its latest published year — 1 point below the 87% England-wide householder average. Hartley Wintney contains Bramshill, Dipley, Elvetham conservation areas (Bramshill designated 2012), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) housing stock sets the design brief on most streets.

Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Hart District Council needs a full application. Hartley Wintney carries at least one Article 4 direction, and conservation areas including Bramshill, Dipley and Elvetham remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Hartley Wintney is determined against an 8-week statutory target.

Bramshill (conservation area designated in 2012), Dipley (conservation area designated in 1988), Elvetham (conservation area designated in 1988), Elvetham Farm (conservation area designated in 1988), Eversley Church Farm (conservation area designated in 2002), Eversley Cross (conservation area designated in 2002), Eversley Street (conservation area designated in 2002), Hartfordbridge (conservation area designated in 2008), Hartley Wintney (conservation area designated in 2008), Hartley Wintney, Church House (conservation area designated in 2008), Hazeley Bottom (conservation area designated in 2012), Heckfield (conservation area designated in 2002), Heckfield (added 2002) (conservation area designated in 2002), Mattingley Green (conservation area designated in 2012), Mattingley, West End (conservation area designated in 2012), Up Green (conservation area designated in 2002), West Green (conservation area designated in 2002), Bramshill (civil parish within Hartley Wintney), Eversley (civil parish within Hartley Wintney), Heckfield (civil parish within Hartley Wintney), Mattingley (civil parish within Hartley Wintney) and Winchfield (civil parish within Hartley Wintney) — these are the Hartley Wintney pockets our drawings cover most. Heritage designations here include Bramshill, Dipley, Elvetham, Elvetham Farm, Eversley Church Farm, Eversley Cross, Eversley Street, Hartfordbridge, Hartley Wintney, Hartley Wintney, Church House, Hazeley Bottom, Heckfield, Heckfield (added 2002), Mattingley Green, Mattingley, West End, Up Green and West Green. Hart District Council weighs each proposal against the adopted Hart local plan and Hart District Council's design guidance for householder work, where the 4,650 homes here are 19% pre-1900, 13% 1973-1982, 9% 1983-1992, which is what sets the realistic roof and rear-projection options. On roofs the borough is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow trussed roofs typical of 1970s building, over Victorian and earlier houses (19% of 4,650 homes), 1970s and early-1980s houses (13%) and 1980s estate houses (9%).

Designations, stock and decisions in Hartley Wintney

Heritage designation is the single biggest variable in Hartley Wintney, and it is address-specific: Bramshill (conservation area designated in 2012), Dipley (conservation area designated in 1988), Elvetham (conservation area designated in 1988), Elvetham Farm (conservation area designated in 1988), Eversley Church Farm (conservation area designated in 2002), Eversley Cross (conservation area designated in 2002), Eversley Street (conservation area designated in 2002), Hartfordbridge (conservation area designated in 2008), Hartley Wintney (conservation area designated in 2008), Hartley Wintney, Church House (conservation area designated in 2008), Hazeley Bottom (conservation area designated in 2012), Heckfield (conservation area designated in 2002), Heckfield (added 2002) (conservation area designated in 2002), Mattingley Green (conservation area designated in 2012), Mattingley, West End (conservation area designated in 2012), Up Green (conservation area designated in 2002) and West Green (conservation area designated in 2002). Inside those boundaries permitted development is curtailed and Hart District 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.

Beyond the designated areas, Hartley Wintney takes in Bramshill, Eversley, Heckfield, Mattingley and Winchfield. Hart District Council has 47 recorded Article 4 directions — check the address before assuming PD applies in Hartley Wintney.

On stock, Hartley Wintney is Victorian and earlier houses (19% of 4,650 homes), 1970s and early-1980s houses (13%) and 1980s estate houses (9%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow trussed roofs typical of 1970s building govern what a loft or rear projection can realistically be. Hart District Council decided 445 householder applications in the latest published year and granted 86%, with 71% issued inside the eight-week target. We work from the council's own published record.

The full build-period split for Hartley Wintney runs pre-1900 19% (900 homes), 1900-1918 4% (200 homes), 1919-1929 4% (170 homes), 1930-1939 2% (110 homes), 1945-1954 6% (290 homes), 1955-1964 6% (270 homes), 1965-1972 6% (300 homes), 1973-1982 13% (620 homes), 1983-1992 9% (430 homes), 1993-1999 5% (250 homes) and 2000-2008 5% (210 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.

Hart District Council also decides for Blackwater and Hawley, Fleet Central, Fleet East, Fleet West, Odiham and Yateley East, so a decision in Hartley Wintney 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.

The Article 4 directions recorded for this council include Bramshill, Broad Oak Odiham Hampshire., Church Farm (Eversley) and Cricket Hill Yateley (Extension). Each removes a specific permitted-development right inside its own boundary, which is why the check is done on the address rather than on the town.

Extension plans built around Hart District Council's rules

Hartley Wintney homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from Victorian and earlier houses (19% of 4,650 homes), 1970s and early-1980s houses (13%) and 1980s estate houses (9%), so a Victorian terrace usually wants a rear or side-return infill, while an interwar semi has room for a wider single-storey wrap or a two-storey side addition. Hart District Council judges every one of them against the adopted Hart local plan and Hart District Council's design guidance for householder work, weighing footprint, height and the impact on the house next door before it looks at the elevations.

That is why the drawings decide the outcome. We set the extension depth against the permitted-development limits precisely, keep the eaves and ridge within the allowances, and plot the 45-degree daylight lines to the neighbours' windows so the case officer can see the amenity test is passed. Hartley Wintney contains Bramshill, Dipley, Elvetham conservation areas (Bramshill designated 2012), so materials, fenestration and roof form are assessed against the appraisal, so we design around it from the first sketch rather than discover it at validation.

Hartley Wintney also protects whole streets — Bramshill, Dipley, Elvetham, Elvetham Farm, Eversley Church Farm, Eversley Cross, Eversley Street, Hartfordbridge, Hartley Wintney, Hartley Wintney, Church House, Hazeley Bottom, Heckfield, Heckfield (added 2002), Mattingley Green, Mattingley, West End, Up Green and West Green among them. Hart District Council has 47 recorded Article 4 directions — check the address before assuming PD applies in Hartley Wintney. On designated land the larger-home extension route and most side extensions stop being permitted development, so we confirm your address against those layers before drawing a line.

Do I need planning permission to extend my house in Hartley Wintney?

Plenty of Hartley Wintney extensions are permitted development and need no planning application — a single-storey rear extension within the depth and height limits is the common case. You will normally need to apply to Hart District Council if any of these apply:

  • The single-storey rear extension is deeper than 3 metres on a terrace or semi, or 4 metres on a detached house (6m/8m needs prior approval under the larger-home scheme)
  • It is a two-storey or double-storey extension, or the rear extension is higher than 4 metres
  • A side extension is wider than half the original house, or more than one storey
  • Any part projects forward of the principal (front) elevation, or the extension covers more than half the garden
  • Your home is in a conservation area such as Bramshill and Dipley, where the larger-home route and side extensions are not permitted development
  • An Article 4 direction applies to your street — Hartley Wintney has several, so this is checked first

Hartley Wintney extension approval rates — live from council data

Below is Hart District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Hart District Council granted 86% of its householder applications in the year to 31 March 2026, and Bramshill shapes what is approved here. A complete, policy-literate extension pack anticipates those pressure points before submission, which is why professionally drawn applications are decided faster and refused less often than DIY ones.

Which extensions get approved in Hartley Wintney

Across Bramshill, Dipley and Elvetham, the extension that lands most often is the single-storey rear addition — a glazed kitchen-diner across the back of the house, kept within the permitted-development depth or taken to a full application where the ground floor wants more. On the borough's victorian and earlier houses (19% of 4,650 homes), a side-return infill frequently pairs with it to square off the plan; on wider 1980s estate houses (9%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.

The 4,650 homes here are 19% pre-1900, 13% 1973-1982, 9% 1983-1992, which is what sets the realistic roof and rear-projection options. We size the extension to the amenity and daylight tests, match the roof and materials to the host house, and keep enough garden to satisfy Hart District Council's space standards — so the scheme answers the borough's questions before an objection can raise them. Where permitted-development rights are used up or removed, we prepare the householder application to the council's extension design guidance instead.

Which extension suits your Hartley Wintney home?

The right extension in Hartley Wintney depends on your house type and how much garden you can give up. This is how the main options compare on planning route and what they add.

Extension typePermitted development?What it addsWhat Hart District Council checks
Single-storey rearOften, within 3m/4m depth (6m/8m via prior approval)Bigger kitchen-diner across the backDepth, height, neighbour daylight (45°)
Side-return infillSometimes, if within width and height limitsSquares off an L-shaped ground floorWidth vs the original house, glazing to boundary
Two-storey rear/sideNo — full applicationExtra bedroom or bathroom aboveBulk, overlooking, 7m rear-boundary gap
Wraparound (rear + side)No — full applicationWhole-width open-plan ground floorCombined footprint and garden retained

Route depends on your street — conservation areas such as Bramshill and Dipley and Article 4 directions can remove permitted-development rights.

Frequently asked questions

Do I need planning permission to extend my house in Hartley Wintney?

Not always. A single-storey rear extension up to 3 metres deep on a terrace or semi, or 4 metres on a detached house, and no higher than 4 metres, is usually permitted development. In Hartley Wintney you will need to apply to Hart District Council for two-storey extensions, side extensions wider than half the house, anything forward of the front wall, deeper rear extensions under the larger-home prior-approval route, and any extension in a conservation area such as Bramshill and Dipley.

How deep can a single-storey rear extension go in Hartley Wintney without planning permission?

Standard permitted development allows 3 metres on a terraced or semi-detached house and 4 metres on a detached one. The larger-home extension scheme can double that to 6 or 8 metres, but it needs a prior-approval notification to Hart District Council and a neighbour-consultation period, and it does not apply on designated land such as Hartley Wintney's conservation areas. We confirm which route your property qualifies for before drawing.

Can I build a double-storey extension in Hartley Wintney?

Two-storey and double-storey extensions almost always need a full householder application to Hart District Council, because they fall outside permitted development on most homes. The council looks closely at bulk, overlooking of neighbours and the 7-metre gap a two-storey rear extension must keep from the rear boundary. We design to those tests and show the daylight and privacy angles on the drawings. This applies to your Hartley Wintney address specifically.

How long does Hart District Council take to decide an extension application?

A householder planning application in Hartley Wintney runs to a statutory eight-week target, a larger-home prior-approval notification to around six weeks including the neighbour-consultation period, and a lawful development certificate to eight weeks. Incomplete submissions stall at validation, so we submit a complete pack and manage officer queries to keep the decision on schedule. Hart District Council is the decision-maker.

Will my extension in Hartley Wintney need building regulations approval as well as planning?

Yes — planning permission and building regulations are separate consents, and almost every extension needs both. Planning governs whether you can build it; building control governs how it is built, covering structure, insulation, drainage and fire safety. We prepare the building-regulations drawings alongside the planning set so Hart District Council's building control or an approved inspector can sign the work off. This applies to your Hartley Wintney address specifically.

How much do extension plans in Hartley Wintney cost?

Every house and brief is different, so we price each Hartley Wintney extension individually and send a fixed, no-obligation quote back within one working day. It covers the full drawing pack with free revisions until Hart District Council approves, and we tell you upfront whether your extension qualifies as permitted development.
