Back-of-house extension drawings for Basingstoke and Deane homes — the glazed kitchen-diner across the rear, drawn to Basingstoke and Deane Borough Council's depth and daylight limits, delivered in days and revised free until your decision, with a free approval-odds check 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.

The rear extension is the workhorse of Basingstoke and Deane home improvement — it is how a dark back kitchen becomes an open family room facing the garden. Because 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%), most back walls sit close to a neighbour on at least one side, and that proximity, not the design, is what Basingstoke and Deane Borough Council scrutinises. The council reads the proposal against the adopted Basingstoke and Deane local plan and Basingstoke and Deane Borough Council's design guidance for householder work, and the first line an officer draws is the 45-degree splay from the neighbour's nearest window.
So the drawings live or die on geometry. We set the depth against the exact permitted-development figure, hold the eaves and the flat-roof or lantern build-up under the 4-metre height ceiling, and show the projection tested against both the 45-degree plan angle and the 25-degree section angle to the neighbouring windows. 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 the rear elevation is composed around it rather than corrected after an objection.
Where the property sits in a conservation area — Ashmansworth, Basingstoke Canal, Bradley, Bramley and Bramley Green, Brown and Chilton Candover, Church Oakley, Church Road, Tadley and Cliddesden among Basingstoke and Deane's — the larger-home extension route is switched off and even a modest rear addition needs consent. Basingstoke and Deane Borough Council has 3 recorded Article 4 directions — check the address before assuming PD applies in the district. We confirm the designation before the survey.
Many single-storey rear extensions in Basingstoke and Deane are permitted development and need no application. You will normally need to apply to Basingstoke and Deane Borough Council, or use the larger-home prior-approval route, if any of these apply:
We draw the depth, the roof build-up and the daylight splays to each neighbour on the page — the tests Basingstoke and Deane Borough Council's officers apply first — and submit a validation-complete pack, whether that is a lawful development certificate, a larger-home prior-approval notice or a full householder application.
Below is Basingstoke and Deane Borough Council's real householder decision record, taken from official planning statistics and refreshed 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. Rear extensions turn most often on neighbour daylight and depth, so a drawing pack that proves those tests upfront is decided faster and refused less often than a DIY submission.

Across Ashmansworth, Basingstoke Canal and Bradley, the approved rear extension is typically a single-storey glazed box within the depth limit, roofed either flat with a lantern or in a shallow mono-pitch, and finished in brick or render to match the host wall. On the borough's 1970s and early-1980s houses (17% of 25,000 homes), keeping the projection to the permitted-development figure often avoids an application entirely; where owners want the full 6 metres, the larger-home route succeeds when the neighbour-consultation period passes without a sustained objection.
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 keep the extension inside the daylight splays, set any glazed roof below the first-floor cill, and retain the garden depth Basingstoke and Deane Borough Council expects — so the back elevation answers the amenity case before a neighbour can lodge one. Two-storey rear extensions we draw with the 7-metre boundary gap and privacy screening resolved on the plan.
We draw rear extensions on every street in the borough. A few of the neighbourhoods where Basingstoke and Deane back-of-house projects come up most often:

How far you can extend at the back in Basingstoke and Deane depends on your house type and the route you take. This is how the options compare.
| Route | Depth allowed | Consent needed | What Basingstoke and Deane Borough Council checks |
|---|---|---|---|
| Standard permitted development | 3m terrace/semi · 4m detached | Lawful development certificate (optional) | Depth, 4m height, materials |
| Larger-home prior approval | 6m terrace/semi · 8m detached | Prior-approval notice + neighbour consultation | Neighbour objections on amenity |
| Full householder application | Beyond the above, or two-storey | Full planning permission | Daylight (45°/25°), bulk, garden retained |
| Conservation area | Case by case | Full planning permission | Character, roof form, boundary treatment |
The larger-home route is switched off on designated land — conservation areas such as Ashmansworth and Basingstoke Canal and Article 4 streets need a full application.
A fixed process built around how Basingstoke and Deane Borough Council validates and decides rear-extension applications — most drawings are submission-ready within seven days of survey.
Send us your Basingstoke and Deane postcode and house type. We confirm your conservation and Article 4 status, how much rear-extension depth you have under permitted development, and score your odds against live Basingstoke and Deane Borough Council decisions.
We measure the original rear wall, floor and eaves levels, side and rear boundary distances and the neighbours' window positions — the numbers the depth limit and daylight splays depend on.
Chartered designers develop the single or two-storey rear extension to your brief, drawn inside the permitted-development limits or to Basingstoke and Deane Borough Council's extension design guidance, with the daylight angles shown.
We submit the certificate, prior-approval notice or application, handle validation and case-officer queries, and revise the drawings free until Basingstoke and Deane Borough Council issues its decision.
Often not. 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 Basingstoke and Deane. You will need to involve Basingstoke and Deane Borough Council for anything deeper via the larger-home route, for two-storey rear extensions, and for any rear extension in a conservation area such as Ashmansworth and Basingstoke Canal, where those permitted-development rights fall away.
The larger-home extension scheme lets a single-storey rear extension reach 6 metres on a terrace or semi, or 8 metres on a detached house — double the standard allowance. It is not automatic: you submit a prior-approval notification to Basingstoke and Deane Borough Council, neighbours are consulted, and if one objects on amenity grounds the council rules on it. It also does not apply on designated land such as Basingstoke and Deane's conservation areas.
It is the daylight test Basingstoke and Deane Borough Council applies to protect neighbours. Drawn on plan, a line at 45 degrees from the midpoint of the neighbour's nearest ground-floor window should not be crossed by your extension; a companion 25-degree line is checked in section. If the projection breaches it, the extension is likely to be shortened or refused, so we test and prove it on the drawings before submission.
A two-storey rear extension almost always needs a full householder application to Basingstoke and Deane Borough Council, as it sits outside permitted development on most homes. The council checks that it stays at least 7 metres from the rear boundary, does not overbear the neighbours and avoids new overlooking. We resolve the boundary gap, privacy and daylight on the plans so the application is decided on its merits.
Frequently, yes. If the rear extension involves work to a shared wall, building up to the boundary, or excavating foundations near a neighbour's structure, the Party Wall etc. Act applies and you must serve notice — this is separate from Basingstoke and Deane Borough Council's planning decision. We flag it early and can prepare the drawings a party-wall surveyor needs alongside the planning set.
