Single-storey, double-storey, rear and side extension drawings for Matlock West homes — measured to Derbyshire Dales District Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
Derbyshire Dales District Council granted 93% of the householder planning decisions it made in its latest published year — 6 points above the 87% England-wide householder average. Matlock West contains Matlock Bank, Matlock Bridge conservation areas (Matlock Bank designated 1986), 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.
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 Matlock Bank and Matlock Bridge those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Matlock West is determined against an 8-week statutory target.
Matlock Bank (conservation area designated in 1986), Matlock Bridge (conservation area designated in 1989), Darley Dale (civil parish within Matlock West), Matlock Town (civil parish within Matlock West) and South Darley (civil parish within Matlock West) — these are the Matlock West pockets our drawings cover most. Heritage designations here include Matlock Bank and Matlock Bridge. Derbyshire Dales District Council weighs each proposal against Derbyshire Dales District Council's development plan and the design policies it applies to householder applications, where the 2,800 homes here are 27% pre-1900, 12% 1955-1964, 11% 1973-1982, 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 shallow gabled roofs typical of that period's building, over Victorian and earlier houses (27% of 2,800 homes), late-1950s and early-1960s houses (12%) and 1970s and early-1980s houses (11%).
Before anything is drawn we check your address against the designations that apply in Matlock West: Matlock Bank (conservation area designated in 1986) and Matlock Bridge (conservation area designated in 1989). Inside those boundaries permitted development is curtailed and Derbyshire Dales 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, Matlock West takes in Darley Dale, Matlock Town and South Darley. No Article 4 direction is recorded for Derbyshire Dales District Council, but Matlock West's 2 conservation areas still limit permitted development on those streets.
On stock, Matlock West is Victorian and earlier houses (27% of 2,800 homes), late-1950s and early-1960s houses (12%) and 1970s and early-1980s houses (11%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow gabled roofs typical of that period's building govern what a loft or rear projection can realistically be. Derbyshire Dales District Council decided 189 householder applications in the latest published year and granted 93%, with 70% issued inside the eight-week target. That decision record, not a national figure, is what we design to.
The full build-period split for Matlock West runs pre-1900 27% (760 homes), 1900-1918 5% (150 homes), 1919-1929 1% (30 homes), 1930-1939 6% (170 homes), 1945-1954 1% (30 homes), 1955-1964 12% (330 homes), 1965-1972 9% (240 homes), 1973-1982 11% (320 homes), 1983-1992 4% (120 homes), 1993-1999 8% (230 homes) and 2000-2008 4% (110 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.
Derbyshire Dales District Council also decides for Ashbourne North, Ashbourne South, Brailsford, Doveridge & Sudbury, Hulland, Matlock East & Tansley, Norbury and Wirksworth, so a decision in Matlock West 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.

Matlock West 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 (27% of 2,800 homes), late-1950s and early-1960s houses (12%) and 1970s and early-1980s houses (11%), 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. Derbyshire Dales District Council judges every one of them against Derbyshire Dales District 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. Matlock West contains Matlock Bank, Matlock Bridge conservation areas (Matlock Bank designated 1986), 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.
Matlock West also protects whole streets — Matlock Bank and Matlock Bridge among them. No Article 4 direction is recorded for Derbyshire Dales District Council, but Matlock West'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 Matlock West 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 Derbyshire Dales District Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships Derbyshire Dales District 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 Derbyshire Dales District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Derbyshire Dales District Council granted 93% of its householder applications in the year to 31 March 2026, and Matlock Bank 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 Matlock Bank, Matlock Bridge and Darley Dale, 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 (27% of 2,800 homes), a side-return infill frequently pairs with it to square off the plan; on wider 1970s and early-1980s houses (11%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The 2,800 homes here are 27% pre-1900, 12% 1955-1964, 11% 1973-1982, 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 Derbyshire Dales District 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 Matlock West projects come up most often:

The right extension in Matlock West 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 Derbyshire Dales District 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 Matlock Bank and Matlock Bridge and Article 4 directions can remove permitted-development rights.
A fixed process built around how Derbyshire Dales District Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Matlock West 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 Derbyshire Dales District 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 Derbyshire Dales District 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 Derbyshire Dales District 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 Matlock West you will need to apply to Derbyshire Dales District 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 Matlock Bank and Matlock Bridge.
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 Derbyshire Dales District Council and a neighbour-consultation period, and it does not apply on designated land such as Matlock West'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 Derbyshire Dales District 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 Matlock West address specifically.
A householder planning application in Matlock West 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. Derbyshire Dales District 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 Derbyshire Dales District Council's building control or an approved inspector can sign the work off. This applies to your Matlock West address specifically.
Every house and brief is different, so we price each Matlock West extension individually and send a fixed, no-obligation quote back within one working day.
