Orangery and conservatory drawings for Kirby Muxloe homes — checked against the Class A rear limits and the 30m² building-regulations exemption, drawn to Blaby District Council's guidance and revised free until your decision.
Blaby District Council granted 96% of the householder planning decisions it made in its latest published year — 9 points above the 87% England-wide householder average. Kirby Muxloe contains the Kirby Fields conservation area (Kirby Fields designated 1990), so materials, fenestration and roof form are assessed against the appraisal, 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.
Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. In conservation areas such as Kirby Fields those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Kirby Muxloe is determined against an 8-week statutory target.
Kirby Fields (conservation area designated in 1990) and Leicester Forest East (civil parish within Kirby Muxloe) — these are the Kirby Muxloe pockets our drawings cover most. Heritage designations here include Kirby Fields. Blaby District Council weighs each proposal against Blaby District Council's adopted local plan and its householder design guidance, where the 2,520 homes here are 30% 1955-1964, 18% 1965-1972, 8% 1919-1929, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow gabled roofs typical of that period's building and shallow-pitched roofs and integral garages typical of that period's building, over late-1950s and early-1960s houses (30% of 2,520 homes), late-1960s and early-1970s houses (18%) and early interwar houses (8%).
Kirby Muxloe's designated heritage is specific, and it is the first thing we check against your address: Kirby Fields (conservation area designated in 1990). Inside those boundaries permitted development is curtailed and Blaby District 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, Kirby Muxloe takes in Leicester Forest East. No Article 4 direction is recorded for Blaby District Council, but Kirby Muxloe's 1 conservation area still limit permitted development on those streets.
On stock, Kirby Muxloe is late-1950s and early-1960s houses (30% of 2,520 homes), late-1960s and early-1970s houses (18%) and early interwar houses (8%) — which is why shallow gabled roofs typical of that period's building and shallow-pitched roofs and integral garages typical of that period's building govern what a loft or rear projection can realistically be. Blaby District Council decided 298 householder applications in the latest published year and granted 96%, with 50% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for Kirby Muxloe runs pre-1900 7% (170 homes), 1900-1918 3% (70 homes), 1919-1929 8% (200 homes), 1930-1939 8% (200 homes), 1945-1954 4% (110 homes), 1955-1964 30% (750 homes), 1965-1972 18% (450 homes), 1973-1982 6% (140 homes), 1983-1992 6% (150 homes), 1993-1999 0% (10 homes) and 2000-2008 4% (90 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.
Blaby District Council also decides for Countesthorpe, Fosse Highcross, Fosse Stoney Cove and Glenfield Ellis, so a decision in Kirby Muxloe 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 Blaby District Council's adopted local plan and its householder design guidance. Kirby Muxloe is largely late-1950s and early-1960s houses (30% of 2,520 homes), late-1960s and early-1970s houses (18%) and early interwar houses (8%), 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 Kirby Fields, 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 Blaby District Council, but Kirby Muxloe's 1 conservation area still limit permitted development on those streets.
Many conservatories are permitted development. You will need an application to Blaby District 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 Blaby District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Blaby District Council granted 96% of its householder applications in the year to 31 March 2026, and Kirby Fields shapes what is approved here. Glazed rear additions are judged on depth, eaves height and how the glazing meets the existing elevation.

Across Kirby Fields and Leicester Forest East, 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-1950s and early-1960s houses (30% of 2,520 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.
Kirby Muxloe contains the Kirby Fields conservation area (Kirby Fields designated 1990), 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 Kirby Muxloe. A few of the areas where they come up most often:
Orangery and conservatory drawings for Kirby Fields — conservation area designated in 1990 — checked against the Class A limits and drawn to Blaby District Council's guidance.
Orangery and conservatory drawings for Leicester Forest East — civil parish within Kirby Muxloe — checked against the Class A limits and drawn to Blaby District 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 Kirby Muxloe postcode and house type. We confirm the Class A limits that apply, check designation status, and score your odds against live Blaby District 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 Blaby District 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 Kirby Muxloe you will need an application to Blaby District Council beyond those limits, and on designated land such as Kirby Fields.
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 Kirby Muxloe address specifically. Blaby District Council is the decision-maker.
For planning, none — both are rear extensions assessed against the same Class A limits by Blaby District 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 Kirby Muxloe 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 Kirby Muxloe address specifically. Blaby District 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 Kirby Muxloe address specifically. Blaby District 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 Blaby District 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 Kirby Muxloe address specifically.
We quote each Kirby Muxloe 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.
