Dormer, hip-to-gable and mansard loft conversion drawings for Basingstoke and Deane homes — prepared to Basingstoke and Deane Borough Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
Basingstoke and Deane Borough Council granted 96% of the householder planning decisions it made in its latest published year — 9 points above the 87% England-wide householder average. Basingstoke and Deane contains Ashmansworth, Basingstoke Canal, Bradley conservation areas (Ashmansworth designated 1989), 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) and postwar (1945–1970) 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 Basingstoke and Deane Borough Council needs a full application. Basingstoke and Deane carries at least one Article 4 direction, and conservation areas including Ashmansworth, Basingstoke Canal and Bradley remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Basingstoke and Deane is determined against an 8-week statutory target.
Ashmansworth (conservation area designated in 1989), Basingstoke Canal (conservation area designated in 1977), Bradley (conservation area designated in 1992), Bramley and Bramley Green (conservation area designated in 1983), Brown and Chilton Candover (conservation area designated in 1981), Church Oakley (conservation area designated in 1976), Church Road, Tadley (conservation area designated in 1982), Cliddesden (conservation area designated in 1981), Basing & Upton Grey (ward of Basingstoke and Deane), Bramley (ward of Basingstoke and Deane), Evingar (ward of Basingstoke and Deane), Oakley & The Candovers (ward of Basingstoke and Deane), Tadley & Pamber (ward of Basingstoke and Deane) and Winklebury & Manydown (ward of Basingstoke and Deane) — these are the Basingstoke and Deane pockets our drawings cover most. Heritage designations here include Ashmansworth, Basingstoke Canal, Bradley, Bramley and Bramley Green, Brown and Chilton Candover, Church Oakley, Church Road, Tadley and Cliddesden. Basingstoke and Deane Borough Council weighs each proposal against the adopted Basingstoke and Deane local plan and Basingstoke and Deane Borough Council's design guidance for householder work, where the 25,000 homes here are 17% 1973-1982, 14% 1965-1972, 7% pre-1900, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow trussed roofs typical of 1970s building and shallow-pitched roofs and integral garages typical of that period's building, over 1970s and early-1980s houses (17% of 25,000 homes), late-1960s and early-1970s houses (14%) and Victorian and earlier houses (7%).
Heritage designation is the single biggest variable in Basingstoke and Deane, and it is address-specific: Ashmansworth (conservation area designated in 1989), Basingstoke Canal (conservation area designated in 1977), Bradley (conservation area designated in 1992), Bramley and Bramley Green (conservation area designated in 1983), Brown and Chilton Candover (conservation area designated in 1981), Church Oakley (conservation area designated in 1976), Church Road, Tadley (conservation area designated in 1982) and Cliddesden (conservation area designated in 1981). Inside those boundaries permitted development is curtailed and Basingstoke and Deane 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.
Beyond the designated areas, Basingstoke and Deane takes in Basing & Upton Grey, Bramley, Evingar, Oakley & The Candovers, Tadley & Pamber and Winklebury & Manydown. Basingstoke and Deane Borough Council has 3 recorded Article 4 directions — check the address before assuming PD applies in the district.
On stock, Basingstoke and Deane is 1970s and early-1980s houses (17% of 25,000 homes), late-1960s and early-1970s houses (14%) and Victorian and earlier houses (7%) — which is why shallow trussed roofs typical of 1970s building and shallow-pitched roofs and integral garages typical of that period's building govern what a loft or rear projection can realistically be. Basingstoke and Deane Borough Council decided 616 householder applications in the latest published year and granted 96%, with 59% issued inside the eight-week target. We work from the council's own published record.
The full build-period split for Basingstoke and Deane runs pre-1900 3% (190 homes), 1900-1918 0% (30 homes), 1919-1929 0% (10 homes), 1930-1939 6% (350 homes), 1945-1954 3% (170 homes), 1955-1964 30% (1,850 homes), 1965-1972 33% (1,990 homes), 1973-1982 4% (260 homes), 1983-1992 5% (310 homes), 1993-1999 4% (220 homes) and 2000-2008 3% (170 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.
Basingstoke and Deane Borough Council also decides for Basing & Upton Grey, Bramley, Evingar, Oakley & The Candovers, Tadley & Pamber and Winklebury & Manydown, so a decision in Basingstoke and Deane 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 Basing View, Basingstoke Town and Chineham and the surrounding villages of Old Basing, Oakley and Sherborne St John. and Chineham Business Park and Hampshire International Business Park. 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.

Basingstoke and Deane's roofs set the brief. The borough is built largely from 1970s and early-1980s houses (17% of 25,000 homes), late-1960s and early-1970s houses (14%) and Victorian and earlier houses (7%), and its lofts sit under shallow trussed roofs typical of 1970s building and shallow-pitched roofs and integral garages typical of that period's building — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Basingstoke and Deane Borough Council assesses loft proposals against the adopted Basingstoke and Deane local plan and Basingstoke and Deane Borough 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 Basingstoke and Deane Borough Council can verify them. Basingstoke and Deane contains Ashmansworth, Basingstoke Canal, Bradley conservation areas (Ashmansworth designated 1989), 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.
Basingstoke and Deane also carries protected streets — Ashmansworth, Basingstoke Canal, Bradley, Bramley and Bramley Green, Brown and Chilton Candover, Church Oakley, Church Road, Tadley and Cliddesden among them. Basingstoke and Deane Borough Council has 3 recorded Article 4 directions — check the address before assuming PD applies in the district. We check your address against those designations before a line is drawn.
Many Basingstoke and Deane 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 Basingstoke and Deane Borough Council if any of these apply:
We draw the roof line, the ridge height and the neighbour's daylight on the page — the relationships Basingstoke and Deane Borough 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 Basingstoke and Deane Borough Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Basingstoke and Deane Borough Council granted 96% of 616 householder decisions in the year to 31 March 2026, 59% of them inside eight weeks. 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 Ashmansworth, Basingstoke Canal and Bradley, 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 shallow trussed roofs typical of 1970s building, that is usually the most efficient use of the roof; where the stock is shallow-pitched roofs and integral garages typical of that period's building, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The 25,000 homes here are 17% 1973-1982, 14% 1965-1972, 7% pre-1900, 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 Basingstoke and Deane Borough 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 Basingstoke and Deane roofs come up most often:

The right loft in Basingstoke and Deane 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 Basingstoke and Deane Borough 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 Ashmansworth and Basingstoke Canal and Article 4 directions can remove permitted-development rights.

Tell us your Basingstoke and Deane 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 Basingstoke and Deane Borough 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 Basingstoke and Deane Borough Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Basingstoke and Deane Borough 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 Basingstoke and Deane the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Ashmansworth and Basingstoke Canal or on streets with an Article 4 direction. Basingstoke and Deane Borough Council is the decision-maker.
Generally no. In conservation areas including Ashmansworth and Basingstoke Canal, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Basingstoke and Deane Borough Council. Basingstoke and Deane Borough Council has 3 recorded Article 4 directions — check the address before assuming PD applies in the district. We check your exact address before drawing.
On shallow trussed roofs typical of 1970s building, common across Basingstoke and Deane, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is shallow-pitched roofs and integral garages typical of that period's 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. Basingstoke and Deane Borough Council is the decision-maker.
A householder planning application in Basingstoke and Deane 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. Basingstoke and Deane Borough Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Basingstoke and Deane Borough 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.
Every roof is different, so we quote each Basingstoke and Deane project individually — a fixed, no-obligation price back within one working day.
