Single-storey, double-storey, rear and side extension drawings for Jericho homes — measured to Oxford City Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
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.
Jericho homes come in a handful of recurring shapes, and each one points to a different extension. 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, so a Victorian terrace usually wants a rear or side-return infill, while an interwar semi has room for a wider single-storey wrap or a two-storey side addition. Oxford City Council judges every one of them against the Oxford Local Plan 2036, weighing footprint, height and the impact on the house next door before it looks at the elevations.
That is why the drawings decide the outcome. We set the extension depth against the permitted-development limits precisely, keep the eaves and ridge within the allowances, and plot the 45-degree daylight lines to the neighbours' windows so the case officer can see the amenity test is passed. 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 we design around it from the first sketch rather than discover it at validation.
Jericho also protects whole streets — Jericho, Walton Manor and Central (City and University) among them. 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. On designated land the larger-home extension route and most side extensions stop being permitted development, so we confirm your address against those layers before drawing a line.

Plenty of Jericho extensions are permitted development and need no planning application — a single-storey rear extension within the depth and height limits is the common case. You will normally need to apply to Oxford City Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships Oxford City Council's officers weigh first — and submit a validation-complete pack, whether that is a lawful development certificate, a prior-approval notification or a full householder application.
Below is Oxford City Council's real householder decision record, drawn 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. A complete, policy-literate extension pack anticipates those pressure points before submission, which is why professionally drawn applications are decided faster and refused less often than DIY ones.

Across Walton Street, Canal Reaches and Cardigan Street, the extension that lands most often is the single-storey rear addition — a glazed kitchen-diner across the back of the house, kept within the permitted-development depth or taken to a full application where the ground floor wants more. On the borough's densely packed victorian artisan and working-class terraces, a side-return infill frequently pairs with it to square off the plan; on wider converted period flats and student lets, a two-storey side or rear extension can add a bedroom above without swallowing the garden.
Plots are exceptionally tight, so rear and side additions are tested hard on neighbour daylight, overlooking and back-garden amenity. We size the extension to the amenity and daylight tests, match the roof and materials to the host house, and keep enough garden to satisfy Oxford City Council's space standards — so the scheme answers the borough's questions before an objection can raise them. Where permitted-development rights are used up or removed, we prepare the householder application to the council's extension design guidance instead.

We draw extensions on every street in the borough. A few of the neighbourhoods where Jericho projects come up most often:

The right extension in Jericho depends on your house type and how much garden you can give up. This is how the main options compare on planning route and what they add.
| Extension type | Permitted development? | What it adds | What Oxford City Council checks |
|---|---|---|---|
| Single-storey rear | Often, within 3m/4m depth (6m/8m via prior approval) | Bigger kitchen-diner across the back | Depth, height, neighbour daylight (45°) |
| Side-return infill | Sometimes, if within width and height limits | Squares off an L-shaped ground floor | Width vs the original house, glazing to boundary |
| Two-storey rear/side | No — full application | Extra bedroom or bathroom above | Bulk, overlooking, 7m rear-boundary gap |
| Wraparound (rear + side) | No — full application | Whole-width open-plan ground floor | Combined footprint and garden retained |
Route depends on your street — conservation areas such as Jericho and Walton Manor and Article 4 directions can remove permitted-development rights.
A fixed process built around how Oxford City Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Jericho postcode and house type. We confirm your conservation and Article 4 status, how much permitted-development depth you have left, and score your odds against live Oxford City Council decisions.
We measure the existing footprint, floor and eaves levels, boundary distances and the neighbours' window positions — the numbers the depth limits and daylight tests depend on.
Chartered designers develop the single-storey, two-storey or side extension to your brief, drawn inside the permitted-development limits or to Oxford City Council's extension design guidance.
We submit the certificate, prior-approval notice or application, manage validation and case-officer queries, and revise the drawings free until Oxford City Council issues its decision.
Not always. 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 apply to Oxford City Council for two-storey extensions, side extensions wider than half the house, anything forward of the front wall, deeper rear extensions under the larger-home prior-approval route, and any extension in a conservation area such as Jericho and Walton Manor.
Standard permitted development allows 3 metres on a terraced or semi-detached house and 4 metres on a detached one. The larger-home extension scheme can double that to 6 or 8 metres, but it needs a prior-approval notification to Oxford City Council and a neighbour-consultation period, and it does not apply on designated land such as Jericho's conservation areas. We confirm which route your property qualifies for before drawing.
Two-storey and double-storey extensions almost always need a full householder application to Oxford City Council, because they fall outside permitted development on most homes. The council looks closely at bulk, overlooking of neighbours and the 7-metre gap a two-storey rear extension must keep from the rear boundary. We design to those tests and show the daylight and privacy angles on the drawings. This applies to your Jericho address specifically.
A householder planning application in Jericho runs to a statutory eight-week target, a larger-home prior-approval notification to around six weeks including the neighbour-consultation period, and a lawful development certificate to eight weeks. Incomplete submissions stall at validation, so we submit a complete pack and manage officer queries to keep the decision on schedule. Oxford City Council is the decision-maker.
Yes — planning permission and building regulations are separate consents, and almost every extension needs both. Planning governs whether you can build it; building control governs how it is built, covering structure, insulation, drainage and fire safety. We prepare the building-regulations drawings alongside the planning set so Oxford City Council's building control or an approved inspector can sign the work off. This applies to your Jericho address specifically.
