Dormer, hip-to-gable and mansard loft conversion drawings for Basing & Upton Grey 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. Basing & Upton Grey contains Basingstoke Canal, Cliddesden, Mapledurwell conservation areas (Basingstoke Canal designated 1977), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant postwar (1945–1970) housing stock sets the design brief on most streets.
The permitted-development ceilings are fixed: 40m³ of new roof volume for a terraced loft and 50m³ for a semi or detached house under Class B, plus a 3m single-storey rear extension on a terrace or 4m on a detached house under Class A. Basing & Upton Grey carries at least one Article 4 direction, and conservation areas including Basingstoke Canal, Cliddesden and Mapledurwell remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Basing & Upton Grey is determined against an 8-week statutory target.
Basingstoke Canal (conservation area designated in 1977), Cliddesden (conservation area designated in 1981), Mapledurwell (conservation area designated in 1981), Newnham (conservation area designated in 1981), Old Basing (conservation area designated in 1973), Tunworth (conservation area designated in 1981), Up Nately (conservation area designated in 1981), Upton Grey (conservation area designated in 1973), Weston Corbett and Weston Patrick (conservation area designated in 1980), Cliddesden (civil parish within Basing & Upton Grey), Herriard (civil parish within Basing & Upton Grey), Mapledurwell and Up Nately (civil parish within Basing & Upton Grey), Newnham (civil parish within Basing & Upton Grey), Old Basing and Lychpit (civil parish within Basing & Upton Grey) and Tunworth (civil parish within Basing & Upton Grey) — these are the Basing & Upton Grey pockets our drawings cover most. Heritage designations here include Basingstoke Canal, Cliddesden, Mapledurwell, Newnham, Old Basing, Tunworth, Up Nately, Upton Grey and Weston Corbett and Weston Patrick. 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 4,410 homes here are 19% 1973-1982, 18% 1983-1992, 10% 1955-1964, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow trussed roofs typical of 1970s building and trussed-rafter roofs typical of 1980s building, over 1970s and early-1980s houses (19% of 4,410 homes), 1980s estate houses (18%) and late-1950s and early-1960s houses (10%).
Before anything is drawn we check your address against the designations that apply in Basing & Upton Grey: Basingstoke Canal (conservation area designated in 1977), Cliddesden (conservation area designated in 1981), Mapledurwell (conservation area designated in 1981), Newnham (conservation area designated in 1981), Old Basing (conservation area designated in 1973), Tunworth (conservation area designated in 1981), Up Nately (conservation area designated in 1981), Upton Grey (conservation area designated in 1973) and Weston Corbett and Weston Patrick (conservation area designated in 1980). 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, Basing & Upton Grey takes in Cliddesden, Herriard, Mapledurwell and Up Nately, Newnham, Old Basing and Lychpit and Tunworth. Basingstoke and Deane Borough Council has 3 recorded Article 4 directions — check the address before assuming PD applies in Basing & Upton Grey.
On stock, Basing & Upton Grey is 1970s and early-1980s houses (19% of 4,410 homes), 1980s estate houses (18%) and late-1950s and early-1960s houses (10%) — which is why shallow trussed roofs typical of 1970s building and trussed-rafter roofs typical of 1980s 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. That decision record, not a national figure, is what we design to.
The full build-period split for Basing & Upton Grey runs pre-1900 9% (380 homes), 1900-1918 2% (100 homes), 1919-1929 2% (90 homes), 1930-1939 5% (240 homes), 1945-1954 5% (210 homes), 1955-1964 10% (460 homes), 1965-1972 7% (310 homes), 1973-1982 19% (840 homes), 1983-1992 18% (790 homes), 1993-1999 9% (380 homes) and 2000-2008 7% (310 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 Bramley, Evingar, Oakley & The Candovers, Tadley & Pamber and Winklebury & Manydown, so a decision in Basing & Upton Grey 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.

Basing & Upton Grey's roofs set the brief. The borough is built largely from 1970s and early-1980s houses (19% of 4,410 homes), 1980s estate houses (18%) and late-1950s and early-1960s houses (10%), and its lofts sit under shallow trussed roofs typical of 1970s building and trussed-rafter roofs typical of 1980s 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. Basing & Upton Grey contains Basingstoke Canal, Cliddesden, Mapledurwell conservation areas (Basingstoke Canal designated 1977), 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.
Basing & Upton Grey also carries protected streets — Basingstoke Canal, Cliddesden, Mapledurwell, Newnham, Old Basing, Tunworth, Up Nately, Upton Grey and Weston Corbett and Weston Patrick among them. Basingstoke and Deane Borough Council has 3 recorded Article 4 directions — check the address before assuming PD applies in Basing & Upton Grey. We check your address against those designations before a line is drawn.
Many Basing & Upton Grey 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 its householder applications in the year to 31 March 2026, and Basingstoke Canal 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 Basingstoke Canal, Cliddesden and Mapledurwell, 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 trussed-rafter roofs typical of 1980s building, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The 4,410 homes here are 19% 1973-1982, 18% 1983-1992, 10% 1955-1964, 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.

The right loft in Basing & Upton Grey 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 Basingstoke Canal and Cliddesden and Article 4 directions can remove permitted-development rights.

Tell us your Basing & Upton Grey 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 Basing & Upton Grey the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Basingstoke Canal and Cliddesden or on streets with an Article 4 direction. Basingstoke and Deane Borough Council is the decision-maker.
Generally no. In conservation areas including Basingstoke Canal and Cliddesden, 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 Basing & Upton Grey. We check your exact address before drawing.
On shallow trussed roofs typical of 1970s building, common across Basing & Upton Grey, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is trussed-rafter roofs typical of 1980s 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 Basing & Upton Grey 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. This applies to your Basing & Upton Grey address specifically.
Every roof is different, so we quote each Basing & Upton Grey project individually — a fixed, no-obligation price back within one working day.
