Orangery and conservatory drawings for Ketton homes — checked against the Class A rear limits and the 30m² building-regulations exemption, drawn to Rutland County Council's guidance and revised free until your decision.
Rutland County Council granted 92% of the householder planning decisions it made in its latest published year — 5 points above the 87% England-wide householder average. Ketton contains Barrowden, Ketton, Tinwell conservation areas (Barrowden designated 1979), 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) 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 Barrowden, Ketton and Tinwell those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Ketton is determined against an 8-week statutory target.
Barrowden (conservation area designated in 1979), Ketton (conservation area designated in 1972), Tinwell (conservation area designated in 1999), Tinwell (civil parish within Ketton), Tixover (civil parish within Ketton) and Barrowden (civil parish within Ketton) — these are the Ketton pockets our drawings cover most. Heritage designations here include Barrowden, Ketton and Tinwell. Rutland County Council weighs each proposal against the adopted Rutland local plan and Rutland County Council's design guidance for householder work, where the 1,280 homes here are 26% pre-1900, 13% 1965-1972, 12% 1973-1982, 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 shallow-pitched roofs and integral garages typical of that period's building, over Victorian and earlier houses (26% of 1,280 homes), late-1960s and early-1970s houses (13%) and 1970s and early-1980s houses (12%).
Before anything is drawn we check your address against the designations that apply in Ketton: Barrowden (conservation area designated in 1979), Ketton (conservation area designated in 1972) and Tinwell (conservation area designated in 1999). Inside those boundaries permitted development is curtailed and Rutland County 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, Ketton takes in Tinwell, Tixover and Barrowden. No Article 4 direction is recorded for Rutland County Council, but Ketton's 3 conservation areas still limit permitted development on those streets.
On stock, Ketton is Victorian and earlier houses (26% of 1,280 homes), late-1960s and early-1970s houses (13%) and 1970s and early-1980s houses (12%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow-pitched roofs and integral garages typical of that period's building govern what a loft or rear projection can realistically be. Rutland County Council decided 269 householder applications in the latest published year and granted 92%, with 74% issued inside the eight-week target. That decision record, not a national figure, is what we design to.
The full build-period split for Ketton runs pre-1900 26% (330 homes), 1919-1929 3% (40 homes), 1930-1939 2% (30 homes), 1945-1954 8% (100 homes), 1955-1964 7% (90 homes), 1965-1972 13% (170 homes), 1973-1982 12% (160 homes), 1983-1992 5% (70 homes), 1993-1999 3% (40 homes) and 2000-2008 11% (140 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.
Rutland County Council also decides for Cottesmore, Normanton, Ryhall & Casterton and Uppingham, so a decision in Ketton 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 Rutland local plan and Rutland County Council's design guidance for householder work. Ketton is largely Victorian and earlier houses (26% of 1,280 homes), late-1960s and early-1970s houses (13%) and 1970s and early-1980s houses (12%), 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 Barrowden and Ketton, 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 Rutland County Council, but Ketton's 3 conservation areas still limit permitted development on those streets.
Many conservatories are permitted development. You will need an application to Rutland County 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 Rutland County Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Rutland County Council granted 92% of its householder applications in the year to 31 March 2026, and Barrowden shapes what is approved here. Glazed rear additions are judged on depth, eaves height and how the glazing meets the existing elevation.

Across Barrowden, Ketton and Tinwell, 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 (26% of 1,280 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.
Ketton contains Barrowden, Ketton, Tinwell conservation areas (Barrowden designated 1979), 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.
We draw glazed rear additions across Ketton. A few of the areas where they come up most often:

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 |

A fixed process covering both consents, because they pull in different directions.
Send us your Ketton postcode and house type. We confirm the Class A limits that apply, check designation status, and score your odds against live Rutland County 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 Rutland County 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 Ketton you will need an application to Rutland County Council beyond those limits, and on designated land such as Barrowden and Ketton.
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 Ketton address specifically. Rutland County Council is the decision-maker.
For planning, none — both are rear extensions assessed against the same Class A limits by Rutland County 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 Ketton 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 Ketton address specifically. Rutland County 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 Ketton address specifically. Rutland County 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 Rutland County 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 Ketton address specifically.
We quote each Ketton orangery or conservatory individually, because the structure and the roof form change the work considerably, and send a fixed, no-obligation quote within one working day.
