Single-storey, double-storey, rear and side extension drawings for Appleby and Brough homes — measured to Westmorland and Furness Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
Westmorland and Furness Council granted 93% of the householder planning decisions it made in its latest published year — 6 points above the 87% England-wide householder average. Appleby and Brough contains Appleby, Church Brough conservation areas (Appleby designated 2022), 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) 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 Appleby and Church Brough those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Appleby and Brough is determined against an 8-week statutory target.
Appleby (conservation area designated in 2022), Church Brough (conservation area designated in 1969), Appleby-in-Westmorland (civil parish within Appleby and Brough), Brough (civil parish within Appleby and Brough), Brough Sowerby (civil parish within Appleby and Brough), Colby (civil parish within Appleby and Brough), Helbeck (civil parish within Appleby and Brough) and Hoff (civil parish within Appleby and Brough) — these are the Appleby and Brough pockets our drawings cover most. Heritage designations here include Appleby and Church Brough. Westmorland and Furness Council weighs each proposal against Westmorland and Furness Council's development plan and the design policies it applies to householder applications, where the 3,580 homes here are 40% pre-1900, 9% 2000-2008, 9% 1993-1999, 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 trussed-rafter roofs typical of 2000s building, over Victorian and earlier houses (40% of 3,580 homes), 2000s houses and apartments (9%) and 1990s estate houses (9%).
Before anything is drawn we check your address against the designations that apply in Appleby and Brough: Appleby (conservation area designated in 2022) and Church Brough (conservation area designated in 1969). Inside those boundaries permitted development is curtailed and Westmorland and Furness 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, Appleby and Brough takes in Appleby-in-Westmorland, Brough, Brough Sowerby, Colby, Helbeck and Hoff. No Article 4 direction is recorded for Westmorland and Furness Council, but Appleby and Brough's 2 conservation areas still limit permitted development on those streets.
On stock, Appleby and Brough is Victorian and earlier houses (40% of 3,580 homes), 2000s houses and apartments (9%) and 1990s estate houses (9%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and trussed-rafter roofs typical of 2000s building govern what a loft or rear projection can realistically be. Westmorland and Furness Council decided 508 householder applications in the latest published year and granted 93%, with 51% issued inside the eight-week target. That decision record, not a national figure, is what we design to.
The full build-period split for Appleby and Brough runs pre-1900 40% (1,420 homes), 1900-1918 1% (30 homes), 1919-1929 1% (20 homes), 1930-1939 2% (60 homes), 1945-1954 3% (100 homes), 1955-1964 3% (120 homes), 1965-1972 8% (300 homes), 1973-1982 6% (220 homes), 1983-1992 8% (300 homes), 1993-1999 9% (310 homes) and 2000-2008 9% (330 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.
Westmorland and Furness Council also decides for Alston and Fellside, Burton and Holme, Eden and Lyvennet Vale, Grange and Cartmel, Hesket and Lazonby, High Furness, Kent Estuary and Levens and Crooklands, so a decision in Appleby and Brough 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.

Appleby and Brough homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from Victorian and earlier houses (40% of 3,580 homes), 2000s houses and apartments (9%) and 1990s estate houses (9%), so a Victorian terrace usually wants a rear or side-return infill, while an interwar semi has room for a wider single-storey wrap or a two-storey side addition. Westmorland and Furness Council judges every one of them against Westmorland and Furness Council's development plan and the design policies it applies to householder applications, weighing footprint, height and the impact on the house next door before it looks at the elevations.
That is why the drawings decide the outcome. We set the extension depth against the permitted-development limits precisely, keep the eaves and ridge within the allowances, and plot the 45-degree daylight lines to the neighbours' windows so the case officer can see the amenity test is passed. Appleby and Brough contains Appleby, Church Brough conservation areas (Appleby designated 2022), so materials, fenestration and roof form are assessed against the appraisal, so we design around it from the first sketch rather than discover it at validation.
Appleby and Brough also protects whole streets — Appleby and Church Brough among them. No Article 4 direction is recorded for Westmorland and Furness Council, but Appleby and Brough's 2 conservation areas still limit permitted development on those streets. On designated land the larger-home extension route and most side extensions stop being permitted development, so we confirm your address against those layers before drawing a line.
Plenty of Appleby and Brough extensions are permitted development and need no planning application — a single-storey rear extension within the depth and height limits is the common case. You will normally need to apply to Westmorland and Furness Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships Westmorland and Furness Council's officers weigh first — and submit a validation-complete pack, whether that is a lawful development certificate, a prior-approval notification or a full householder application.
Below is Westmorland and Furness Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Westmorland and Furness Council granted 93% of its householder applications in the year to 31 March 2026, and Appleby shapes what is approved here. A complete, policy-literate extension pack anticipates those pressure points before submission, which is why professionally drawn applications are decided faster and refused less often than DIY ones.

Across Appleby, Church Brough and Appleby-in-Westmorland, the extension that lands most often is the single-storey rear addition — a glazed kitchen-diner across the back of the house, kept within the permitted-development depth or taken to a full application where the ground floor wants more. On the borough's victorian and earlier houses (40% of 3,580 homes), a side-return infill frequently pairs with it to square off the plan; on wider 1990s estate houses (9%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The 3,580 homes here are 40% pre-1900, 9% 2000-2008, 9% 1993-1999, which is what sets the realistic roof and rear-projection options. We size the extension to the amenity and daylight tests, match the roof and materials to the host house, and keep enough garden to satisfy Westmorland and Furness Council's space standards — so the scheme answers the borough's questions before an objection can raise them. Where permitted-development rights are used up or removed, we prepare the householder application to the council's extension design guidance instead.
We draw extensions on every street in the borough. A few of the neighbourhoods where Appleby and Brough projects come up most often:

The right extension in Appleby and Brough depends on your house type and how much garden you can give up. This is how the main options compare on planning route and what they add.
| Extension type | Permitted development? | What it adds | What Westmorland and Furness Council checks |
|---|---|---|---|
| Single-storey rear | Often, within 3m/4m depth (6m/8m via prior approval) | Bigger kitchen-diner across the back | Depth, height, neighbour daylight (45°) |
| Side-return infill | Sometimes, if within width and height limits | Squares off an L-shaped ground floor | Width vs the original house, glazing to boundary |
| Two-storey rear/side | No — full application | Extra bedroom or bathroom above | Bulk, overlooking, 7m rear-boundary gap |
| Wraparound (rear + side) | No — full application | Whole-width open-plan ground floor | Combined footprint and garden retained |
Route depends on your street — conservation areas such as Appleby and Church Brough and Article 4 directions can remove permitted-development rights.
A fixed process built around how Westmorland and Furness Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Appleby and Brough postcode and house type. We confirm your conservation and Article 4 status, how much permitted-development depth you have left, and score your odds against live Westmorland and Furness Council decisions.
We measure the existing footprint, floor and eaves levels, boundary distances and the neighbours' window positions — the numbers the depth limits and daylight tests depend on.
Chartered designers develop the single-storey, two-storey or side extension to your brief, drawn inside the permitted-development limits or to Westmorland and Furness Council's extension design guidance.
We submit the certificate, prior-approval notice or application, manage validation and case-officer queries, and revise the drawings free until Westmorland and Furness Council issues its decision.
Not always. A single-storey rear extension up to 3 metres deep on a terrace or semi, or 4 metres on a detached house, and no higher than 4 metres, is usually permitted development. In Appleby and Brough you will need to apply to Westmorland and Furness Council for two-storey extensions, side extensions wider than half the house, anything forward of the front wall, deeper rear extensions under the larger-home prior-approval route, and any extension in a conservation area such as Appleby and Church Brough.
Standard permitted development allows 3 metres on a terraced or semi-detached house and 4 metres on a detached one. The larger-home extension scheme can double that to 6 or 8 metres, but it needs a prior-approval notification to Westmorland and Furness Council and a neighbour-consultation period, and it does not apply on designated land such as Appleby and Brough's conservation areas. We confirm which route your property qualifies for before drawing.
Two-storey and double-storey extensions almost always need a full householder application to Westmorland and Furness Council, because they fall outside permitted development on most homes. The council looks closely at bulk, overlooking of neighbours and the 7-metre gap a two-storey rear extension must keep from the rear boundary. We design to those tests and show the daylight and privacy angles on the drawings. This applies to your Appleby and Brough address specifically.
A householder planning application in Appleby and Brough runs to a statutory eight-week target, a larger-home prior-approval notification to around six weeks including the neighbour-consultation period, and a lawful development certificate to eight weeks. Incomplete submissions stall at validation, so we submit a complete pack and manage officer queries to keep the decision on schedule. Westmorland and Furness Council is the decision-maker.
Yes — planning permission and building regulations are separate consents, and almost every extension needs both. Planning governs whether you can build it; building control governs how it is built, covering structure, insulation, drainage and fire safety. We prepare the building-regulations drawings alongside the planning set so Westmorland and Furness Council's building control or an approved inspector can sign the work off. This applies to your Appleby and Brough address specifically.
