Householder planning in Eye — the record

Peterborough City Council granted 90.3% of the householder planning decisions it made in its latest published year — level with the 90.3% England-wide householder average. The flat fenland setting and drainage dykes bring surface-water and flood-risk considerations on village-edge plots, 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.

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. In conservation areas such as Eye, Thorney and Northborough those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Eye is determined against an 8-week statutory target.

Eye village (the medieval church and historic core inside the conservation area), Eye Green (village-edge housing around the former brick pits and green), Thorney (a planned estate-village conservation area to the east), Newborough (a fenland village on the northern approach), Parnwell (1980s New Town-era estate housing towards the city) and Northborough (a stone-built conservation village to the north-west) — these are the Eye pockets our drawings cover most. Heritage designations here include Eye, Thorney, Northborough and Stanground. Peterborough City Council weighs each proposal against the Peterborough Local Plan (2019), where the Eye conservation area is held to the pantile-and-brick fenland vernacular of the historic core. On roofs the borough is clay-tile and pantile roofs in the historic village core and gabled and hipped roofs on the interwar and modern housing, over historic fenland village core around the medieval church, interwar and postwar village-edge housing and modern estate and infill development on the northern growth edge.

Extension plans built around Peterborough City Council's rules

Eye homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from historic fenland village core around the medieval church, interwar and postwar village-edge housing and modern estate and infill development on the northern growth edge, 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 flat fenland setting and drainage dykes bring surface-water and flood-risk considerations on village-edge plots, so we design around it from the first sketch rather than discover it at validation.

Eye also protects whole streets — Eye, Thorney, Northborough and Stanground among them. Eye has no house-to-HMO Article 4 direction, but the Eye conservation area protects the historic village core around the church and Crowland Road, removing permitted-development rights on its protected streets. 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.

Do I need planning permission to extend my house in Eye?

Plenty of Eye 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:

  • The single-storey rear extension is deeper than 3 metres on a terrace or semi, or 4 metres on a detached house (6m/8m needs prior approval under the larger-home scheme)
  • It is a two-storey or double-storey extension, or the rear extension is higher than 4 metres
  • A side extension is wider than half the original house, or more than one storey
  • Any part projects forward of the principal (front) elevation, or the extension covers more than half the garden
  • Your home is in a conservation area such as Eye and Thorney, where the larger-home route and side extensions are not permitted development

Eye extension approval rates — live from council data

Below is Peterborough City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Peterborough approves the large majority of householder applications, and in Eye the fenland flood-risk regime and the village conservation core are the main pressure points. 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.

Which extensions get approved in Eye

Across Eye village, Eye Green and Thorney, 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 fenland village core around the medieval church, a side-return infill frequently pairs with it to square off the plan; on wider modern estate and infill development on the northern growth edge, a two-storey side or rear extension can add a bedroom above without swallowing the garden.

The Eye conservation area is held to the pantile-and-brick fenland vernacular of the historic core. 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.

Which extension suits your Eye home?

The right extension in Eye 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 typePermitted development?What it addsWhat Peterborough City Council checks
Single-storey rearOften, within 3m/4m depth (6m/8m via prior approval)Bigger kitchen-diner across the backDepth, height, neighbour daylight (45°)
Side-return infillSometimes, if within width and height limitsSquares off an L-shaped ground floorWidth vs the original house, glazing to boundary
Two-storey rear/sideNo — full applicationExtra bedroom or bathroom aboveBulk, overlooking, 7m rear-boundary gap
Wraparound (rear + side)No — full applicationWhole-width open-plan ground floorCombined footprint and garden retained

Route depends on your street — conservation areas such as Eye and Thorney and Article 4 directions can remove permitted-development rights.

Four steps to an approved Eye extension

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.

  1. 1

    Free approval check

    Tell us your Eye 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.

  2. 2

    Measured survey

    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.

  3. 3

    Extension design & drawings

    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.

  4. 4

    Submission & follow-through

    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.

Frequently asked questions

Do I need planning permission to extend my house in Eye?

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 Eye 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 Eye and Thorney.

How deep can a single-storey rear extension go in Eye without planning permission?

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 Eye's conservation areas. We confirm which route your property qualifies for before drawing.

Can I build a double-storey extension in Eye?

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 Eye address specifically.

How long does Peterborough City Council take to decide an extension application?

A householder planning application in Eye 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.

Will my extension in Eye need building regulations approval as well as planning?

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 a registered building control approver can sign the work off. This applies to your Eye address specifically.

How much do extension plans in Eye cost?

Every house and brief is different, so we price each Eye extension individually and send a fixed, no-obligation quote back within one working day. It covers the full drawing pack with free revisions until Peterborough City Council approves, and we tell you upfront whether your extension qualifies as permitted development.
