Dormer, hip-to-gable and mansard loft conversion drawings for Eye homes — prepared to Peterborough City Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
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.
Eye's roofs set the brief. 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, and its lofts sit under clay-tile and pantile roofs in the historic village core and gabled and hipped roofs on the interwar and modern housing — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Peterborough City Council assesses loft proposals against the Peterborough Local Plan (2019), and its case officers read each roof against the pair next door and the wider street before they read the plans.
That makes drawing quality decisive. We measure ridge and eaves heights, roof pitch and the existing stair, calculate the added volume against the permitted-development limits exactly, and show the workings on the drawings so Peterborough City Council can verify them. The flat fenland setting and drainage dykes bring surface-water and flood-risk considerations on village-edge plots, so we resolve it on the page rather than leave it for the case officer to raise.
Eye also carries protected 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. We check your address against those designations before a line is drawn.
Many Eye loft conversions proceed without planning permission — a rear dormer within the permitted-development volume limits (40 cubic metres on a terrace, 50 on a semi or detached house) is usually lawful. You will normally need a full application to Peterborough City Council if any of these apply:
We draw the roof line, the ridge height and the neighbour's daylight on the page — the relationships Peterborough City Council's officers check first — and submit a validation-complete pack, whether that is a lawful development certificate or a full householder application.
Below is Peterborough City Council's real householder decision record, pulled from official planning statistics and updated 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. Professionally prepared loft drawings anticipate those pressure points before submission, which is why complete, policy-literate packs are decided faster and refused less often than DIY applications.

Across Eye village, Eye Green and Thorney, the recurring loft is the rear dormer — a box across the back roof slope that turns a cramped attic into a full-height double bedroom and en-suite. On clay-tile and pantile roofs in the historic village core, that is usually the most efficient use of the roof; where the stock is gabled and hipped roofs on the interwar and modern housing, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The Eye conservation area is held to the pantile-and-brick fenland vernacular of the historic core. We draw the dormer inside the volume allowance, keep the flat-roof build-up below the ridge, and set the face back from the eaves as the rules require — so the pack answers Peterborough City Council's questions before they are asked. Where permitted-development rights are exhausted or removed, we prepare a householder application composed to the borough's roof-alteration guidance instead.
We draw loft conversions on every street in the borough. A few of the neighbourhoods where Eye roofs come up most often:

The right loft in Eye depends on your roof. This is how the main types compare on planning route and the space they add.
| Loft type | Permitted development? | Space & headroom | What Peterborough City Council checks |
|---|---|---|---|
| Rear dormer | Usually yes, within volume limits | Full-height double room at the back | Volume, set-back from eaves, ridge height |
| Hip-to-gable | No — full application | Extends the whole side of the roof | Roof bulk and the symmetry of the pair |
| Mansard | No — full application | Maximum floor area across the roof | Street character, especially in conservation areas |
| Rooflights only | Usually yes (Class C) | Light and headroom, no extra footprint | Whether rooflights sit within the existing slope |
Route depends on your street — conservation areas such as Eye and Thorney and Article 4 directions can remove permitted-development rights.
A fixed process built around how Peterborough City Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your Eye postcode and roof type. We confirm your conservation and Article 4 status, how much permitted-development volume you have left, and score your odds against live Peterborough City Council decisions.
We measure ridge and eaves heights, roof pitch, joist levels and the existing stair — the numbers the volume calculation and head heights depend on.
Chartered designers develop the dormer, hip-to-gable or mansard to your brief, drawn inside the Class B limits or to Peterborough City Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Peterborough City Council issues its decision.
Often not. A rear dormer within 40 cubic metres on a terrace, or 50 on a semi-detached or detached house, set back from the eaves and no higher than the ridge, is usually permitted development. In Eye the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Eye and Thorney or on streets with an Article 4 direction. Peterborough City Council is the decision-maker.
Generally no. In conservation areas including Eye and Thorney, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Peterborough City Council. 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. We check your exact address before drawing.
On clay-tile and pantile roofs in the historic village core, common across Eye, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is gabled and hipped roofs on the interwar and modern housing, a hip-to-gable followed by a rear dormer gains far more usable space but needs planning permission. Our survey confirms which your roof supports before we draw. Peterborough City Council is the decision-maker.
A householder planning application in Eye runs to a statutory eight-week target, and a lawful development certificate to eight weeks as well, though validation can add time if the pack is incomplete. We submit validation-complete drawings and manage case-officer queries to keep the decision on track. Peterborough City Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Peterborough City Council is council-stamped proof of that — worth having, because every buyer's solicitor will ask for it when you sell. We prepare and submit the certificate application with the same drawing pack. This applies to your Eye address specifically.
Every roof is different, so we quote each Eye project individually — a fixed, no-obligation price back within one working day.
