Single-storey, double-storey, rear and side extension drawings for Ilkley homes — measured to Bradford Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
Bradford Council granted 86% of the householder planning decisions it made in its latest published year — 1 point below the 87% England-wide householder average. Much of Ilkley abuts moorland and Green Belt below Ilkley Moor, sharply limiting extensions and outbuildings on the upper slopes, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) and Edwardian (1901–1910) 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 Ilkley, Ben Rhydding and Addingham those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Ilkley is determined against an 8-week statutory target.
Ilkley town centre (Victorian spa villas and stone terraces inside the conservation area), Ben Rhydding (detached and semi-detached stone villas in their own conservation area), Wells Road (large hillside villas climbing toward Ilkley Moor), Addingham (the historic weaving village of stone cottages up the Wharfe), Burley in Wharfedale (mill-village stone terraces and later houses in the conservation area) and Menston (commuter stone housing on the moorland fringe) — these are the Ilkley pockets our drawings cover most. Heritage designations here include Ilkley, Ben Rhydding, Addingham, Burley in Wharfedale and Menston. Bradford Council weighs each proposal against the Bradford Local Plan / Core Strategy, where spa-era villa proportions and boundary walls are protected, so front and roof alterations are held to the Victorian character. On roofs the borough is Yorkshire stone-slate pitched and hipped roofs on the villas and gabled stone-slate roofs on the terraces, over grand Victorian and Edwardian stone villas from the spa-town era, millstone-grit terraces and cottages and detached moor-edge houses below Ilkley Moor.
Ilkley homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from grand Victorian and Edwardian stone villas from the spa-town era, millstone-grit terraces and cottages and detached moor-edge houses below Ilkley Moor, 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. Bradford Council judges every one of them against the Bradford Local Plan / Core Strategy, 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. Much of Ilkley abuts moorland and Green Belt below Ilkley Moor, sharply limiting extensions and outbuildings on the upper slopes, so we design around it from the first sketch rather than discover it at validation.
Ilkley also protects whole streets — Ilkley, Ben Rhydding, Addingham, Burley in Wharfedale and Menston among them. Ilkley carries no Article 4 direction — Bradford's six directions all sit in the inner districts — but the Ilkley, Ben Rhydding and Addingham conservation areas remove permitted-development rights across most of the Victorian spa-town 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 Ilkley 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 Bradford Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships Bradford 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 Bradford Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Bradford grants a solid majority of householder applications in Ilkley, though moorland Green Belt and the protected spa-town villa character shape what is approved on many plots. 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 Ilkley town centre, Ben Rhydding and Wells Road, 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 grand victorian and edwardian stone villas from the spa-town era, a side-return infill frequently pairs with it to square off the plan; on wider detached moor-edge houses below ilkley moor, a two-storey side or rear extension can add a bedroom above without swallowing the garden.
Spa-era villa proportions and boundary walls are protected, so front and roof alterations are held to the Victorian character. 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 Bradford 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 Ilkley projects come up most often:

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