Orangery and conservatory drawings for Kelsale & Yoxford homes — checked against the Class A rear limits and the 30m² building-regulations exemption, drawn to East Suffolk Council's guidance and revised free until your decision.
East Suffolk Council granted 95% of the householder planning decisions it made in its latest published year — 8 points above the 87% England-wide householder average. Kelsale & Yoxford contains Huntingfield, Peasenhall and Sibton, Yoxford conservation areas (Huntingfield designated 1988), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), 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. In conservation areas such as Huntingfield, Peasenhall and Sibton and Yoxford those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Kelsale & Yoxford is determined against an 8-week statutory target.
Huntingfield (conservation area designated in 1988), Peasenhall and Sibton (conservation area designated in 1972), Yoxford (conservation area designated in 1973), Sibton (civil parish within Kelsale & Yoxford), Ubbeston (civil parish within Kelsale & Yoxford), Walpole (civil parish within Kelsale & Yoxford), Yoxford (civil parish within Kelsale & Yoxford), Heveningham (civil parish within Kelsale & Yoxford) and Huntingfield (civil parish within Kelsale & Yoxford) — these are the Kelsale & Yoxford pockets our drawings cover most. Heritage designations here include Huntingfield, Peasenhall and Sibton and Yoxford. East Suffolk Council weighs each proposal against the adopted East Suffolk local plan and East Suffolk Council's design guidance for householder work, where the 1,860 homes here are 42% pre-1900, 7% 1945-1954, 6% 1930-1939, which is what sets the realistic roof and rear-projection options. On roofs the borough is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and simple gabled and hipped roofs typical of early postwar building, over Victorian and earlier houses (42% of 1,860 homes), early postwar houses (7%) and 1930s semi-detached and detached houses (6%).
What is permitted in Kelsale & Yoxford turns on designation first, so that is where we start: Huntingfield (conservation area designated in 1988), Peasenhall and Sibton (conservation area designated in 1972) and Yoxford (conservation area designated in 1973). Inside those boundaries permitted development is curtailed and East Suffolk Council assesses materials, window detail and roof form against the area's own appraisal, so a scheme that would be waved through two streets away can need a full application here.
Beyond the designated areas, Kelsale & Yoxford takes in Sibton, Ubbeston, Walpole, Yoxford, Heveningham and Huntingfield. No Article 4 direction is recorded for East Suffolk Council, but Kelsale & Yoxford's 3 conservation areas still limit permitted development on those streets.
On stock, Kelsale & Yoxford is Victorian and earlier houses (42% of 1,860 homes), early postwar houses (7%) and 1930s semi-detached and detached houses (6%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and simple gabled and hipped roofs typical of early postwar building govern what a loft or rear projection can realistically be. East Suffolk Council decided 1,008 householder applications in the latest published year and granted 95%, with 60% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Kelsale & Yoxford runs pre-1900 42% (780 homes), 1900-1918 1% (10 homes), 1919-1929 1% (20 homes), 1930-1939 6% (120 homes), 1945-1954 7% (130 homes), 1955-1964 6% (120 homes), 1965-1972 4% (80 homes), 1973-1982 6% (120 homes), 1983-1992 4% (80 homes), 1993-1999 3% (50 homes) and 2000-2008 5% (100 homes). That distribution is why pre-1900 detailing dominates the drawings here, and it is measured from council-tax records rather than assumed from the street name.
East Suffolk Council also decides for Beccles & Worlingham, Bungay & Wainford, Carlford & Fynn Valley, Deben, Eastern Felixstowe, Framlingham, Halesworth & Blything and Harbour & Normanston, so a decision in Kelsale & Yoxford sits inside a wider pattern of decisions we track across the same authority — useful when an officer cites a precedent from the next area over.

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 adopted East Suffolk local plan and East Suffolk Council's design guidance for householder work. Kelsale & Yoxford is largely Victorian and earlier houses (42% of 1,860 homes), early postwar houses (7%) and 1930s semi-detached and detached houses (6%), 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 Huntingfield and Peasenhall and Sibton, rear glazing is assessed on visibility from the street and on the effect on the rear elevation's character. No Article 4 direction is recorded for East Suffolk Council, but Kelsale & Yoxford's 3 conservation areas still limit permitted development on those streets.
Many conservatories are permitted development. You will need an application to East Suffolk 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 East Suffolk Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. East Suffolk Council granted 95% of its householder applications in the year to 31 March 2026, and Huntingfield shapes what is approved here. Glazed rear additions are judged on depth, eaves height and how the glazing meets the existing elevation.

Across Huntingfield, Peasenhall and Sibton and Yoxford, 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 victorian and earlier houses (42% of 1,860 homes), 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.
Kelsale & Yoxford contains Huntingfield, Peasenhall and Sibton, Yoxford conservation areas (Huntingfield designated 1988), so materials, fenestration and roof form are assessed against the appraisal. 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.

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 Kelsale & Yoxford postcode and house type. We confirm the Class A limits that apply, check designation status, and score your odds against live East Suffolk 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 East Suffolk 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 Kelsale & Yoxford you will need an application to East Suffolk Council beyond those limits, and on designated land such as Huntingfield and Peasenhall and Sibton.
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 Kelsale & Yoxford address specifically. East Suffolk Council is the decision-maker.
For planning, none — both are rear extensions assessed against the same Class A limits by East Suffolk 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 Kelsale & Yoxford 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 Kelsale & Yoxford address specifically. East Suffolk 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 Kelsale & Yoxford address specifically. East Suffolk 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 East Suffolk 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 Kelsale & Yoxford address specifically.
