Orangery and conservatory drawings for Cricklade & Latton homes — checked against the Class A rear limits and the 30m² building-regulations exemption, drawn to Wiltshire Council's guidance and revised free until your decision.
Wiltshire Council granted 96% of the householder planning decisions it made in its latest published year — 9 points above the 87% England-wide householder average. Cricklade & Latton contains CRICKLADE, MARSTON MEYSEY conservation areas (CRICKLADE designated 1970), 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.
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. Cricklade & Latton carries at least one Article 4 direction, and conservation areas including CRICKLADE and MARSTON MEYSEY remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Cricklade & Latton is determined against an 8-week statutory target.
CRICKLADE (conservation area designated in 1970), MARSTON MEYSEY (conservation area designated in 1974), Cricklade (civil parish within Cricklade & Latton), Latton (civil parish within Cricklade & Latton) and Marston Maisey (civil parish within Cricklade & Latton) — these are the Cricklade & Latton pockets our drawings cover most. Heritage designations here include CRICKLADE and MARSTON MEYSEY. Wiltshire Council weighs each proposal against the adopted Wiltshire local plan and Wiltshire Council's design guidance for householder work, where the 2,380 homes here are 23% 1965-1972, 15% pre-1900, 13% 1973-1982, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow-pitched roofs and integral garages typical of that period's building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, over late-1960s and early-1970s houses (23% of 2,380 homes), Victorian and earlier houses (15%) and 1970s and early-1980s houses (13%).
What is permitted in Cricklade & Latton turns on designation first, so that is where we start: CRICKLADE (conservation area designated in 1970) and MARSTON MEYSEY (conservation area designated in 1974). Inside those boundaries permitted development is curtailed and Wiltshire 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, Cricklade & Latton takes in Cricklade, Latton and Marston Maisey. Wiltshire Council has 48 recorded Article 4 directions, removing permitted development for rear and side extensions and other roof alterations, including rooflights — check the address before assuming PD applies in Cricklade & Latton.
On stock, Cricklade & Latton is late-1960s and early-1970s houses (23% of 2,380 homes), Victorian and earlier houses (15%) and 1970s and early-1980s houses (13%) — which is why shallow-pitched roofs and integral garages typical of that period's building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building govern what a loft or rear projection can realistically be. Wiltshire Council decided 1,779 householder applications in the latest published year and granted 96%, with 53% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Cricklade & Latton runs pre-1900 15% (350 homes), 1900-1918 3% (60 homes), 1930-1939 3% (70 homes), 1945-1954 3% (60 homes), 1955-1964 5% (130 homes), 1965-1972 23% (540 homes), 1973-1982 13% (310 homes), 1983-1992 10% (230 homes), 1993-1999 5% (110 homes) and 2000-2008 8% (200 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.
Wiltshire Council also decides for Aldbourne & Ramsbury, Amesbury West, Avon Valley, Box & Colerne, By Brook, Corsham Ladbrook, Corsham Pickwick and Corsham Without, so a decision in Cricklade & Latton 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 Article 4 directions recorded for this council include Ashley, Avebury, Baydon 1 and Baydon 2. Each removes a specific permitted-development right inside its own boundary, which is why the check is done on the address rather than on the town.

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 Wiltshire local plan and Wiltshire Council's design guidance for householder work. Cricklade & Latton is largely late-1960s and early-1970s houses (23% of 2,380 homes), Victorian and earlier houses (15%) and 1970s and early-1980s houses (13%), 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 CRICKLADE and MARSTON MEYSEY, rear glazing is assessed on visibility from the street and on the effect on the rear elevation's character. Wiltshire Council has 48 recorded Article 4 directions, removing permitted development for rear and side extensions and other roof alterations, including rooflights — check the address before assuming PD applies in Cricklade & Latton.
Many conservatories are permitted development. You will need an application to Wiltshire 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 Wiltshire Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Wiltshire Council granted 96% of its householder applications in the year to 31 March 2026, and CRICKLADE shapes what is approved here. Glazed rear additions are judged on depth, eaves height and how the glazing meets the existing elevation.

Across CRICKLADE, MARSTON MEYSEY and Cricklade, 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 late-1960s and early-1970s houses (23% of 2,380 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.
Cricklade & Latton contains CRICKLADE, MARSTON MEYSEY conservation areas (CRICKLADE designated 1970), 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 Cricklade & Latton postcode and house type. We confirm the Class A limits that apply, check designation status, and score your odds against live Wiltshire 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 Wiltshire 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 Cricklade & Latton you will need an application to Wiltshire Council beyond those limits, and on designated land such as CRICKLADE and MARSTON MEYSEY.
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 Cricklade & Latton address specifically. Wiltshire Council is the decision-maker.
For planning, none — both are rear extensions assessed against the same Class A limits by Wiltshire 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 Cricklade & Latton 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 Cricklade & Latton address specifically. Wiltshire 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 Cricklade & Latton address specifically. Wiltshire 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 Wiltshire 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 Cricklade & Latton address specifically.
