Back-of-house extension drawings for Jericho homes — the glazed kitchen-diner across the rear, drawn to Oxford City Council's depth and daylight limits, delivered in days and revised free until your decision, with a free approval-odds check first.
Oxford City Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. The Jericho conservation area protects an unusually uniform Victorian terrace roofscape, so dormers, roof lights and rear additions are judged against the rhythm of the whole street, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837) and Victorian (1837–1901) housing stock sets the design brief on most streets.
Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. Jericho carries at least one Article 4 direction, and conservation areas including Jericho, Walton Manor and Central (City and University) remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Jericho is determined against an 8-week statutory target.
Walton Street (the district's spine, a run of Victorian frontages and canal-era terraces), Canal Reaches (narrow artisan terraces built between the Oxford Canal and the railway), Cardigan Street (tightly gridded two-storey terraces of the original workers' housing), St Barnabas (streets gathered around G.E. Street's Italianate St Barnabas Church), Jericho Wharf (former boatyard land alongside the canal, mixing old terraces with newer infill) and Great Clarendon Street (terraces once tied to the Oxford University Press works) — these are the Jericho pockets our drawings cover most. Heritage designations here include Jericho, Walton Manor and Central (City and University). Oxford City Council weighs each proposal against the Oxford Local Plan 2036, where plots are exceptionally tight, so rear and side additions are tested hard on neighbour daylight, overlooking and back-garden amenity. Many Jericho terraces are subdivided into flats or let as student houses, and converted flats carry no householder permitted-development rights.. On roofs the borough is shallow-pitched gabled and hipped roofs on the two-storey terraces and steep slate roofs on the canal-side cottages, over densely packed Victorian artisan and working-class terraces, Georgian and early-Victorian cottages near the Oxford Canal and converted period flats and student lets.
The rear extension is the workhorse of Jericho home improvement — it is how a dark back kitchen becomes an open family room facing the garden. Because the borough is built largely from densely packed Victorian artisan and working-class terraces, Georgian and early-Victorian cottages near the Oxford Canal and converted period flats and student lets, most back walls sit close to a neighbour on at least one side, and that proximity, not the design, is what Oxford City Council scrutinises. The council reads the proposal against the Oxford Local Plan 2036, 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. The Jericho conservation area protects an unusually uniform Victorian terrace roofscape, so dormers, roof lights and rear additions are judged against the rhythm of the whole street, so the rear elevation is composed around it rather than corrected after an objection.
Where the property sits in a conservation area — Jericho, Walton Manor and Central (City and University) among Jericho's — the larger-home extension route is switched off and even a modest rear addition needs consent. Oxford operates a city-wide Article 4 direction (in force since 25 February 2012) that removes the permitted right to change a family home into a small C4 house in multiple occupation, so an HMO conversion anywhere in the city needs planning permission — and the conservation areas layer further controls on frontages, roofs and windows on top. We confirm the designation before the survey.
Many single-storey rear extensions in Jericho are permitted development and need no application. You will normally need to apply to Oxford City 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 Oxford City 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 Oxford City Council's real householder decision record, taken from official planning statistics and refreshed as new data lands. Oxford grants around 87% of the applications it decides, and in Jericho the binding constraints are the tight Victorian terrace grain and the conservation-area roofscape rather than the headline rate. 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 Walton Street, Canal Reaches and Cardigan Street, 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 densely packed victorian artisan and working-class terraces, 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.
Plots are exceptionally tight, so rear and side additions are tested hard on neighbour daylight, overlooking and back-garden amenity. We keep the extension inside the daylight splays, set any glazed roof below the first-floor cill, and retain the garden depth Oxford City 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 Jericho back-of-house projects come up most often:

How far you can extend at the back in Jericho depends on your house type and the route you take. This is how the options compare.
| Route | Depth allowed | Consent needed | What Oxford City 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 Jericho and Walton Manor and Article 4 streets need a full application.
A fixed process built around how Oxford City Council validates and decides rear-extension applications — most drawings are submission-ready within seven days of survey.
Send us your Jericho 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 Oxford City 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 Oxford City 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 Oxford City 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 Jericho. You will need to involve Oxford City 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 Jericho and Walton Manor, 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 Oxford City 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 Jericho's conservation areas.
It is the daylight test Oxford City 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. This applies to your Jericho address specifically.
A two-storey rear extension almost always needs a full householder application to Oxford City 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. This applies to your Jericho address specifically.
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 Oxford City Council's planning decision. We flag it early and can prepare the drawings a party-wall surveyor needs alongside the planning set. This applies to your Jericho address specifically.
We price each Jericho rear extension on its own footprint and send a fixed, no-obligation quote within one working day. It covers the full drawing pack with free revisions until Oxford City Council approves, and we confirm at the outset whether your extension is permitted development, needs prior approval, or a full application.
