Back-of-house extension drawings for Cottesmore homes — the glazed kitchen-diner across the rear, drawn to Rutland County Council's depth and daylight limits, delivered in days and revised free until your decision, with a free approval-odds check first.
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. Cottesmore contains Cottesmore, Market Overton conservation areas (Cottesmore designated 1981), 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. In conservation areas such as Cottesmore and Market Overton those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Cottesmore is determined against an 8-week statutory target.
Cottesmore (conservation area designated in 1981), Market Overton (conservation area designated in 1981), Market Overton (civil parish within Cottesmore) and Barrow (civil parish within Cottesmore) — these are the Cottesmore pockets our drawings cover most. Heritage designations here include Cottesmore and Market Overton. Rutland County Council weighs each proposal against Rutland County Council's development plan and the design policies it applies to householder applications, where the 1,260 homes here are 38% 1955-1964, 16% 1965-1972, 15% pre-1900, 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 (38% of 1,260 homes), late-1960s and early-1970s houses (16%) and Victorian and earlier houses (15%).
What is permitted in Cottesmore turns on designation first, so that is where we start: Cottesmore (conservation area designated in 1981) and Market Overton (conservation area designated in 1981). 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, Cottesmore takes in Market Overton and Barrow. No Article 4 direction is recorded for Rutland County Council, but Cottesmore's 2 conservation areas still limit permitted development on those streets.
On stock, Cottesmore is late-1950s and early-1960s houses (38% of 1,260 homes), late-1960s and early-1970s houses (16%) and Victorian and earlier houses (15%) — 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. Rutland County Council decided 269 householder applications in the latest published year and granted 92%, with 74% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Cottesmore runs pre-1900 15% (190 homes), 1900-1918 2% (20 homes), 1930-1939 2% (20 homes), 1945-1954 3% (40 homes), 1955-1964 38% (480 homes), 1965-1972 16% (200 homes), 1973-1982 8% (100 homes), 1983-1992 3% (40 homes), 1993-1999 2% (20 homes) and 2000-2008 6% (80 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 Ketton, Normanton, Ryhall & Casterton and Uppingham, so a decision in Cottesmore 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 rear extension is the workhorse of Cottesmore home improvement — it is how a dark back kitchen becomes an open family room facing the garden. Because the borough is built largely from late-1950s and early-1960s houses (38% of 1,260 homes), late-1960s and early-1970s houses (16%) and Victorian and earlier houses (15%), most back walls sit close to a neighbour on at least one side, and that proximity, not the design, is what Rutland County Council scrutinises. The council reads the proposal against Rutland County Council's development plan and the design policies it applies to householder applications, and the first line an officer draws is the 45-degree splay from the neighbour's nearest window.
So the drawings live or die on geometry. We set the depth against the exact permitted-development figure, hold the eaves and the flat-roof or lantern build-up under the 4-metre height ceiling, and show the projection tested against both the 45-degree plan angle and the 25-degree section angle to the neighbouring windows. Cottesmore contains Cottesmore, Market Overton conservation areas (Cottesmore designated 1981), so materials, fenestration and roof form are assessed against the appraisal, so the rear elevation is composed around it rather than corrected after an objection.
Where the property sits in a conservation area — Cottesmore and Market Overton among Cottesmore's — the larger-home extension route is switched off and even a modest rear addition needs consent. No Article 4 direction is recorded for Rutland County Council, but Cottesmore's 2 conservation areas still limit permitted development on those streets. We confirm the designation before the survey.
Many single-storey rear extensions in Cottesmore are permitted development and need no application. You will normally need to apply to Rutland County Council, or use the larger-home prior-approval route, if any of these apply:
We draw the depth, the roof build-up and the daylight splays to each neighbour on the page — the tests Rutland County Council's officers apply first — and submit a validation-complete pack, whether that is a lawful development certificate, a larger-home prior-approval notice or a full householder application.
Below is Rutland County Council's real householder decision record, taken 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 Cottesmore shapes what is approved here. Rear extensions turn most often on neighbour daylight and depth, so a drawing pack that proves those tests upfront is decided faster and refused less often than a DIY submission.

Across Cottesmore, Market Overton and Market Overton, the approved rear extension is typically a single-storey glazed box within the depth limit, roofed either flat with a lantern or in a shallow mono-pitch, and finished in brick or render to match the host wall. On the borough's late-1950s and early-1960s houses (38% of 1,260 homes), keeping the projection to the permitted-development figure often avoids an application entirely; where owners want the full 6 metres, the larger-home route succeeds when the neighbour-consultation period passes without a sustained objection.
The 1,260 homes here are 38% 1955-1964, 16% 1965-1972, 15% pre-1900, which is what sets the realistic roof and rear-projection options. We keep the extension inside the daylight splays, set any glazed roof below the first-floor cill, and retain the garden depth Rutland County Council expects — so the back elevation answers the amenity case before a neighbour can lodge one. Two-storey rear extensions we draw with the 7-metre boundary gap and privacy screening resolved on the plan.
We draw rear extensions on every street in the borough. A few of the neighbourhoods where Cottesmore back-of-house projects come up most often:

How far you can extend at the back in Cottesmore depends on your house type and the route you take. This is how the options compare.
| Route | Depth allowed | Consent needed | What Rutland County Council checks |
|---|---|---|---|
| Standard permitted development | 3m terrace/semi · 4m detached | Lawful development certificate (optional) | Depth, 4m height, materials |
| Larger-home prior approval | 6m terrace/semi · 8m detached | Prior-approval notice + neighbour consultation | Neighbour objections on amenity |
| Full householder application | Beyond the above, or two-storey | Full planning permission | Daylight (45°/25°), bulk, garden retained |
| Conservation area | Case by case | Full planning permission | Character, roof form, boundary treatment |
The larger-home route is switched off on designated land — conservation areas such as Cottesmore and Market Overton and Article 4 streets need a full application.
A fixed process built around how Rutland County Council validates and decides rear-extension applications — most drawings are submission-ready within seven days of survey.
Send us your Cottesmore postcode and house type. We confirm your conservation and Article 4 status, how much rear-extension depth you have under permitted development, and score your odds against live Rutland County Council decisions.
We measure the original rear wall, floor and eaves levels, side and rear boundary distances and the neighbours' window positions — the numbers the depth limit and daylight splays depend on.
Chartered designers develop the single or two-storey rear extension to your brief, drawn inside the permitted-development limits or to Rutland County Council's extension design guidance, with the daylight angles shown.
We submit the certificate, prior-approval notice or application, handle validation and case-officer queries, and revise the drawings free until Rutland County Council issues its decision.
Often not. 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 Cottesmore. You will need to involve Rutland County Council for anything deeper via the larger-home route, for two-storey rear extensions, and for any rear extension in a conservation area such as Cottesmore and Market Overton, where those permitted-development rights fall away.
The larger-home extension scheme lets a single-storey rear extension reach 6 metres on a terrace or semi, or 8 metres on a detached house — double the standard allowance. It is not automatic: you submit a prior-approval notification to Rutland County Council, neighbours are consulted, and if one objects on amenity grounds the council rules on it. It also does not apply on designated land such as Cottesmore's conservation areas.
It is the daylight test Rutland County Council applies to protect neighbours. Drawn on plan, a line at 45 degrees from the midpoint of the neighbour's nearest ground-floor window should not be crossed by your extension; a companion 25-degree line is checked in section. If the projection breaches it, the extension is likely to be shortened or refused, so we test and prove it on the drawings before submission. This applies to your Cottesmore address specifically.
A two-storey rear extension almost always needs a full householder application to Rutland County Council, as it sits outside permitted development on most homes. The council checks that it stays at least 7 metres from the rear boundary, does not overbear the neighbours and avoids new overlooking. We resolve the boundary gap, privacy and daylight on the plans so the application is decided on its merits. This applies to your Cottesmore address specifically.
Frequently, yes. If the rear extension involves work to a shared wall, building up to the boundary, or excavating foundations near a neighbour's structure, the Party Wall etc. Act applies and you must serve notice — this is separate from Rutland County Council's planning decision. We flag it early and can prepare the drawings a party-wall surveyor needs alongside the planning set. This applies to your Cottesmore address specifically.
We price each Cottesmore rear extension on its own footprint and send a fixed, no-obligation quote within one working day. It covers the full drawing pack with free revisions until Rutland County Council approves, and we confirm at the outset whether your extension is permitted development, needs prior approval, or a full application.
