Dormer, hip-to-gable and mansard loft conversion drawings for Hartley Wintney homes — prepared to Hart District Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
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%).
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.

Hartley Wintney's roofs set the brief. 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%), and its lofts sit under steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow trussed roofs typical of 1970s building — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Hart District Council assesses loft proposals against the adopted Hart local plan and Hart District Council's design guidance for householder work, and its case officers read each roof against the pair next door and the wider street before they read the plans.
That makes drawing quality decisive. We measure ridge and eaves heights, roof pitch and the existing stair, calculate the added volume against the permitted-development limits exactly, and show the workings on the drawings so Hart District Council can verify them. Hartley Wintney contains Bramshill, Dipley, Elvetham conservation areas (Bramshill designated 2012), so materials, fenestration and roof form are assessed against the appraisal, so we resolve it on the page rather than leave it for the case officer to raise.
Hartley Wintney also carries protected 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. We check your address against those designations before a line is drawn.
Many Hartley Wintney loft conversions proceed without planning permission — a rear dormer within the permitted-development volume limits (40 cubic metres on a terrace, 50 on a semi or detached house) is usually lawful. You will normally need a full application to Hart District Council if any of these apply:
We draw the roof line, the ridge height and the neighbour's daylight on the page — the relationships Hart District Council's officers check first — and submit a validation-complete pack, whether that is a lawful development certificate or a full householder application.
Below is Hart District Council's real householder decision record, pulled from official planning statistics and updated 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. Professionally prepared loft drawings anticipate those pressure points before submission, which is why complete, policy-literate packs are decided faster and refused less often than DIY applications.

Across Bramshill, Dipley and Elvetham, the recurring loft is the rear dormer — a box across the back roof slope that turns a cramped attic into a full-height double bedroom and en-suite. On steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, that is usually the most efficient use of the roof; where the stock is shallow trussed roofs typical of 1970s building, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
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 draw the dormer inside the volume allowance, keep the flat-roof build-up below the ridge, and set the face back from the eaves as the rules require — so the pack answers Hart District Council's questions before they are asked. Where permitted-development rights are exhausted or removed, we prepare a householder application composed to the borough's roof-alteration guidance instead.
We draw loft conversions on every street in the borough. A few of the neighbourhoods where Hartley Wintney roofs come up most often:

The right loft in Hartley Wintney depends on your roof. This is how the main types compare on planning route and the space they add.
| Loft type | Permitted development? | Space & headroom | What Hart District Council checks |
|---|---|---|---|
| Rear dormer | Usually yes, within volume limits | Full-height double room at the back | Volume, set-back from eaves, ridge height |
| Hip-to-gable | No — full application | Extends the whole side of the roof | Roof bulk and the symmetry of the pair |
| Mansard | No — full application | Maximum floor area across the roof | Street character, especially in conservation areas |
| Rooflights only | Usually yes (Class C) | Light and headroom, no extra footprint | Whether rooflights sit within the existing slope |
Route depends on your street — conservation areas such as Bramshill and Dipley and Article 4 directions can remove permitted-development rights.
A fixed process built around how Hart District Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your Hartley Wintney postcode and roof type. We confirm your conservation and Article 4 status, how much permitted-development volume you have left, and score your odds against live Hart District Council decisions.
We measure ridge and eaves heights, roof pitch, joist levels and the existing stair — the numbers the volume calculation and head heights depend on.
Chartered designers develop the dormer, hip-to-gable or mansard to your brief, drawn inside the Class B limits or to Hart District Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Hart District Council issues its decision.
Often not. A rear dormer within 40 cubic metres on a terrace, or 50 on a semi-detached or detached house, set back from the eaves and no higher than the ridge, is usually permitted development. In Hartley Wintney the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Bramshill and Dipley or on streets with an Article 4 direction. Hart District Council is the decision-maker.
Generally no. In conservation areas including Bramshill and Dipley, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Hart District Council. Hart District Council has 47 recorded Article 4 directions — check the address before assuming PD applies in Hartley Wintney. We check your exact address before drawing.
On steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, common across Hartley Wintney, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is shallow trussed roofs typical of 1970s building, a hip-to-gable followed by a rear dormer gains far more usable space but needs planning permission. Our survey confirms which your roof supports before we draw. Hart District Council is the decision-maker.
A householder planning application in Hartley Wintney runs to a statutory eight-week target, and a lawful development certificate to eight weeks as well, though validation can add time if the pack is incomplete. We submit validation-complete drawings and manage case-officer queries to keep the decision on track. Hart District Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Hart District Council is council-stamped proof of that — worth having, because every buyer's solicitor will ask for it when you sell. We prepare and submit the certificate application with the same drawing pack. This applies to your Hartley Wintney address specifically.
Every roof is different, so we quote each Hartley Wintney project individually — a fixed, no-obligation price back within one working day. The quote covers the full drawing pack with free revisions until Hart District Council approves, and we tell you upfront whether your loft qualifies as permitted development.
