Orangery and conservatory drawings for Willerby and Kirk Ella homes — checked against the Class A rear limits and the 30m² building-regulations exemption, drawn to East Riding of Yorkshire Council's guidance and revised free until your decision.
East Riding of Yorkshire Council granted 92% of the householder planning decisions it made in its latest published year — 5 points above the 87% England-wide householder average. Willerby and Kirk Ella contains Kirk Ella, West Ella conservation areas (Kirk Ella designated 1974), 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.
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. Willerby and Kirk Ella carries at least one Article 4 direction, and conservation areas including Kirk Ella and West Ella remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Willerby and Kirk Ella is determined against an 8-week statutory target.
Kirk Ella (conservation area designated in 1974), West Ella (conservation area designated in 1974), Kirk Ella (civil parish within Willerby and Kirk Ella) and Willerby (civil parish within Willerby and Kirk Ella) — these are the Willerby and Kirk Ella pockets our drawings cover most. Heritage designations here include Kirk Ella and West Ella. East Riding of Yorkshire Council weighs each proposal against East Riding of Yorkshire Council's development plan and the design policies it applies to householder applications, where the 6,310 homes here are 25% 1930-1939, 20% 1955-1964, 18% 1965-1972, which is what sets the realistic roof and rear-projection options. On roofs the borough is hipped roofs with shallow pitches typical of 1930s building and shallow gabled roofs typical of that period's building, over 1930s semi-detached and detached houses (25% of 6,310 homes), late-1950s and early-1960s houses (20%) and late-1960s and early-1970s houses (18%).
Before anything is drawn we check your address against the designations that apply in Willerby and Kirk Ella: Kirk Ella (conservation area designated in 1974) and West Ella (conservation area designated in 1974). Inside those boundaries permitted development is curtailed and East Riding of Yorkshire 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, Willerby and Kirk Ella takes in Kirk Ella and Willerby. East Riding of Yorkshire Council has 11 recorded Article 4 directions, removing permitted development for rear and side extensions — check the address before assuming PD applies in Willerby and Kirk Ella.
On stock, Willerby and Kirk Ella is 1930s semi-detached and detached houses (25% of 6,310 homes), late-1950s and early-1960s houses (20%) and late-1960s and early-1970s houses (18%) — which is why hipped roofs with shallow pitches typical of 1930s building and shallow gabled roofs typical of that period's building govern what a loft or rear projection can realistically be. East Riding of Yorkshire Council decided 830 householder applications in the latest published year and granted 92%, with 95% issued inside the eight-week target. That decision record, not a national figure, is what we design to.
The full build-period split for Willerby and Kirk Ella runs pre-1900 3% (180 homes), 1900-1918 2% (110 homes), 1919-1929 2% (130 homes), 1930-1939 25% (1,600 homes), 1945-1954 4% (280 homes), 1955-1964 20% (1,250 homes), 1965-1972 18% (1,110 homes), 1973-1982 6% (390 homes), 1983-1992 7% (460 homes), 1993-1999 3% (210 homes) and 2000-2008 2% (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.
East Riding of Yorkshire Council also decides for Beverley Rural, Bridlington North, Bridlington South, Dale, Driffield and Rural, East Wolds and Coastal, Goole South and Hessle, so a decision in Willerby and Kirk Ella 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 Alpine Villa (Beck Cottage), Atwick, Atwick Hall, Atwick, Clifton House, Atwick and Green View, Atwick. 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 East Riding of Yorkshire Council's development plan and the design policies it applies to householder applications. Willerby and Kirk Ella is largely 1930s semi-detached and detached houses (25% of 6,310 homes), late-1950s and early-1960s houses (20%) and late-1960s and early-1970s houses (18%), 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 Kirk Ella and West Ella, rear glazing is assessed on visibility from the street and on the effect on the rear elevation's character. East Riding of Yorkshire Council has 11 recorded Article 4 directions, removing permitted development for rear and side extensions — check the address before assuming PD applies in Willerby and Kirk Ella.
Many conservatories are permitted development. You will need an application to East Riding of Yorkshire 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 Riding of Yorkshire Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. East Riding of Yorkshire Council granted 92% of its householder applications in the year to 31 March 2026, and Kirk Ella shapes what is approved here. Glazed rear additions are judged on depth, eaves height and how the glazing meets the existing elevation.

Across Kirk Ella, West Ella and Kirk Ella, 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 1930s semi-detached and detached houses (25% of 6,310 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.
Willerby and Kirk Ella contains Kirk Ella, West Ella conservation areas (Kirk Ella designated 1974), 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 Willerby and Kirk Ella. 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 Willerby and Kirk Ella postcode and house type. We confirm the Class A limits that apply, check designation status, and score your odds against live East Riding of Yorkshire 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 Riding of Yorkshire 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 Willerby and Kirk Ella you will need an application to East Riding of Yorkshire Council beyond those limits, and on designated land such as Kirk Ella and West Ella.
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 Willerby and Kirk Ella address specifically. East Riding of Yorkshire Council is the decision-maker.
For planning, none — both are rear extensions assessed against the same Class A limits by East Riding of Yorkshire 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 Willerby and Kirk Ella 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 Willerby and Kirk Ella address specifically. East Riding of Yorkshire 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 Willerby and Kirk Ella address specifically. East Riding of Yorkshire 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 Riding of Yorkshire 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 Willerby and Kirk Ella address specifically.
