Single-storey, double-storey, rear and side extension drawings for Werrington homes — measured to Peterborough City Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
Peterborough City Council granted 88% of the householder planning decisions it made in its latest published year — 1 point above the 87% England-wide householder average. The 1970s township layout of cul-de-sacs and shared greens shapes how extensions and outbuildings read on the street, which is where a policy-literate drawing pack earns its keep. Its dominant interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Before permission is required, Class B allows 40m³ of added loft volume on a terrace and 50m³ on a semi or detached house, and Class A allows a 3m single-storey rear extension on a terrace or 4m on a detached house. Werrington carries at least one Article 4 direction, and conservation areas including Werrington, Peakirk and Glinton remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Werrington is determined against an 8-week statutory target.
Werrington village (the old village core and church inside the conservation area), Werrington township (1970s New Town estates laid out off the Werrington parkway), Gunthorpe (postwar and New Town-era housing to the south), Paston (old village fabric absorbed into the northern townships), Glinton (a stone-built conservation village on the northern edge) and Peakirk (a small fenland conservation village north of the township) — these are the Werrington pockets our drawings cover most. Heritage designations here include Werrington, Peakirk, Glinton and Northborough. Peterborough City Council weighs each proposal against the Peterborough Local Plan (2019), where the Werrington conservation area is held to the village vernacular rather than the surrounding New Town estate character. On roofs the borough is shallow-pitched roofs on the 1970s township housing and gabled and hipped roofs on the interwar and village stock, over historic village core around St John's church, 1970s New Town township housing and interwar and postwar semis on the older approaches.
Werrington homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from historic village core around St John's church, 1970s New Town township housing and interwar and postwar semis on the older approaches, 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. Peterborough City Council judges every one of them against the Peterborough Local Plan (2019), 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 1970s township layout of cul-de-sacs and shared greens shapes how extensions and outbuildings read on the street, so we design around it from the first sketch rather than discover it at validation.
Werrington also protects whole streets — Werrington, Peakirk, Glinton and Northborough among them. The Werrington conservation area, designated in June 1969 around the old village core with its church, pubs and shops, removes permitted-development rights on its historic streets while the wider township falls under the council's broader conservation and design controls. 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 Werrington 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 Peterborough 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 Peterborough 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 Peterborough City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Peterborough grants a clear majority of householder applications, and in Werrington the village conservation area and the estate grain of the 1970s township are the leading design tests. 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 Werrington village, Werrington township and Gunthorpe, 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 historic village core around st john's church, a side-return infill frequently pairs with it to square off the plan; on wider interwar and postwar semis on the older approaches, a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The Werrington conservation area is held to the village vernacular rather than the surrounding New Town estate character. 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 Peterborough 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 Werrington projects come up most often:

The right extension in Werrington 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 Peterborough 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 Werrington and Peakirk and Article 4 directions can remove permitted-development rights.
A fixed process built around how Peterborough City Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Werrington 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 Peterborough 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 Peterborough 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 Peterborough 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 Werrington you will need to apply to Peterborough 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 Werrington and Peakirk.
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 Peterborough City Council and a neighbour-consultation period, and it does not apply on designated land such as Werrington'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 Peterborough 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 Werrington address specifically.
A householder planning application in Werrington 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. Peterborough 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 Peterborough City Council's building control or an approved inspector can sign the work off. This applies to your Werrington address specifically.
Every house and brief is different, so we price each Werrington extension individually and send a fixed, no-obligation quote back within one working day.
