Orangery and conservatory drawings for Werrington homes — checked against the Class A rear limits and the 30m² building-regulations exemption, drawn to Peterborough City Council's guidance and revised free until your decision.
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.
The difference is not marketing. A conservatory is predominantly glazed — at least three quarters of the roof and half of the walls — which is what earns it the building-regulations exemption. An orangery has a solid masonry perimeter with a glazed lantern set into a flat roof, so it usually reads as a conventional extension for building control and has to meet Part L thermal standards, Part A structure and Part B fire like any other room.
Both are judged the same way for planning: as rear extensions, against the Class A depth, height and eaves limits, and against the Peterborough Local Plan (2019). Werrington is largely historic village core around St John's church, 1970s New Town township housing and interwar and postwar semis on the older approaches, and the design question is usually whether the glazing reads as a lightweight addition to that stock or as a bolted-on conservatory kit. On period houses, an orangery with a properly proportioned lantern almost always sits better than a full-height glazed box.
In conservation areas such as Werrington and Peakirk, rear glazing is assessed on visibility from the street and on the effect on the rear elevation's character. 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.
Many conservatories are permitted development. You will need an application to Peterborough City Council where any of these apply:
We check the scheme against the Class A planning limits and against the building-regulations exemption at the same time, so you know before committing whether you are building an exempt conservatory or a fully regulated room.
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. Glazed rear additions are judged on depth, eaves height and how the glazing meets the existing elevation.

Across Werrington village, Werrington township and Gunthorpe, the schemes that succeed keep the eaves below the neighbour's ground-floor cill line, set the glazing back from the boundary, and use a solid parapet or brick perimeter to tie the addition into the house. On historic village core around st john's church, a lantern set in a flat roof usually reads better than a pitched glazed roof, and it avoids the summer overheating that makes full conservatories unusable for months a year.
The 1970s township layout of cul-de-sacs and shared greens shapes how extensions and outbuildings read on the street. The decision worth making early is whether to keep the separating doors. Keeping them preserves the building-regulations exemption but leaves you with a room that is not part of the house; removing them creates one continuous space but brings the whole addition inside Part L, which changes the glazing specification and usually the heating design too. We set out both versions before you commit.
We draw glazed rear additions across Werrington. A few of the areas where they come up most often:

Orangery and conservatory drawings for Werrington township — 1970s New Town estates laid out off the Werrington parkway — checked against the Class A limits and drawn to Peterborough City Council's guidance.
Orangery and conservatory drawings for Gunthorpe — postwar and New Town-era housing to the south — checked against the Class A limits and drawn to Peterborough City Council's guidance.
Orangery and conservatory drawings for Paston — old village fabric absorbed into the northern townships — checked against the Class A limits and drawn to Peterborough City Council's guidance.
Orangery and conservatory drawings for Glinton — a stone-built conservation village on the northern edge — checked against the Class A limits and drawn to Peterborough City Council's guidance.
Orangery and conservatory drawings for Peakirk — a small fenland conservation village north of the township — checked against the Class A limits and drawn to Peterborough City Council's guidance.
The planning test is the same for both. The building-regulations test is not.
| Structure | Planning route | Building regulations | Practical effect |
|---|---|---|---|
| Conservatory under 30m², doors retained | Class A rear extension limits | Largely exempt | Cheaper build, unheated in winter |
| Conservatory, doors removed | Class A rear extension limits | Part L applies in full | Continuous space, higher spec glazing |
| Orangery with solid perimeter and lantern | Class A rear extension limits | Fully regulated | Usable year round, better on period houses |
| Any of the above beyond the depth limits | Full householder application | As above | 8-week determination |
| Any of the above on designated land | Full householder application | As above | Design and visibility assessed |
Planning limits from the GPDO 2015, Schedule 2, Part 1, Class A; exemption criteria from the Building Regulations 2010, Schedule 2, Class 7.
A fixed process covering both consents, because they pull in different directions.
Send us your Werrington postcode and house type. We confirm the Class A limits that apply, check designation status, and score your odds against live Peterborough City Council decisions.
We measure the rear elevation, eaves and ground levels, and the neighbouring boundary — the numbers that decide both the projection limit and the 2-metre eaves rule.
Chartered designers develop the orangery or conservatory to your brief, and we set out clearly whether it stays inside the building-regulations exemption or becomes a fully regulated room.
We submit the certificate or application, manage validation and officer queries, and revise free until Peterborough City Council decides.
Often not. A conservatory is treated as a rear extension, so it can be permitted development within the Class A limits — 3 metres of projection on a terrace or semi, 4 metres on a detached house, with eaves under 3 metres where it sits within 2 metres of a boundary. In Werrington you will need an application to Peterborough City Council beyond those limits, and on designated land such as Werrington and Peakirk.
A conservatory is largely exempt if it is under 30 square metres, at ground level, separated from the house by external-quality doors, and has at least 75% of its roof and 50% of its walls glazed. Glazing, electrics and any drainage work still have to comply. Remove the separating doors and the exemption falls away — the space becomes part of the house and Part L thermal standards apply. This applies to your Werrington address specifically. Peterborough City Council is the decision-maker.
For planning, none — both are rear extensions assessed against the same Class A limits by Peterborough City Council. The difference is in building control: an orangery's solid perimeter and flat roof with a lantern usually means it fails the glazing test for exemption, so it is fully regulated. That is why an orangery costs more to build but is comfortable in January. This applies to your Werrington address specifically.
Usually yes at the rear, though permitted-development rights are narrower on designated land and an Article 4 direction can remove them entirely. The assessment turns on whether the addition is visible from the street and how it meets the original rear elevation. A restrained orangery in matching brick with a lantern is consistently easier to get through than a proprietary glazed conservatory. This applies to your Werrington address specifically. Peterborough City Council is the decision-maker.
A fully glazed roof will, unless it is specified for it. That is the practical reason most of our clients end up building an orangery instead: a solid insulated roof perimeter with a lantern gives daylight without the greenhouse effect, and keeps the space usable across the year. We raise it at design stage because it is much cheaper to solve on paper than after the build. This applies to your Werrington address specifically. Peterborough City Council is the decision-maker.
If you excavate foundations within 3 metres of a neighbouring structure and deeper than its foundations, or build on the boundary itself, the Party Wall etc. Act 1996 applies and notice must be served. That is separate from Peterborough City Council's planning decision. We flag it at design stage so the notice period does not delay the start on site. This applies to your Werrington address specifically.
