Single-storey, double-storey, rear and side extension drawings for Adel homes — measured to Leeds City Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
Leeds City Council granted 83% of the householder planning decisions it made in its latest published year — 4 points below the 87% England-wide householder average. Extensive green belt around Adel sharply limits the scale of extensions and new outbuildings, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Leeds City Council needs a full application. Adel carries at least one Article 4 direction, and conservation areas including Adel St John's, Weetwood and Meanwood remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Adel is determined against an 8-week statutory target.
Adel village (stone cottages around Church Lane and the Norman church of St John the Baptist), Long Causeway (interwar and postwar detached houses), Holt Park (1970s estate housing and a district centre), Tinshill (postwar semis and detached houses), Cookridge edge (detached houses on the northern green-belt fringe) and Weetwood edge (Victorian villas and interwar houses towards the ring road) — these are the Adel pockets our drawings cover most. Heritage designations here include Adel St John's, Weetwood and Meanwood. Leeds City Council weighs each proposal against Leeds Local Plan / Core Strategy and the relevant SPDs, where the Adel St John's conservation area protects the setting of the Norman church and its stone cottages. On roofs the borough is hipped and gabled roofs on the interwar and postwar houses and pitched stone-slate roofs on the older village cottages, over interwar and postwar detached and semi-detached houses, stone cottages around Adel village and the church, large modern detached houses on the green-belt fringe and 1960s–70s estate housing at Holt Park and Tinshill.
Adel homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from interwar and postwar detached and semi-detached houses, stone cottages around Adel village and the church, large modern detached houses on the green-belt fringe and 1960s–70s estate housing at Holt Park and Tinshill, 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. Leeds City Council judges every one of them against Leeds Local Plan / Core Strategy and the relevant SPDs, 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. Extensive green belt around Adel sharply limits the scale of extensions and new outbuildings, so we design around it from the first sketch rather than discover it at validation.
Adel also protects whole streets — Adel St John's, Weetwood and Meanwood among them. The northern edge of Leeds' HMO Article 4 ring runs through neighbouring Cookridge and catches the southern fringe of Adel, where a change to a small (C4) house in multiple occupation needs planning permission rather than permitted development. 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 Adel 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 Leeds City Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships Leeds City 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 Leeds City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Leeds approves the majority of householder schemes in Adel, with green belt and the semi-rural village character the decisive factors 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 Adel village, Long Causeway and Holt Park, 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 interwar and postwar detached and semi-detached houses, a side-return infill frequently pairs with it to square off the plan; on wider 1960s–70s estate housing at holt park and tinshill, a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The Adel St John's conservation area protects the setting of the Norman church and its stone cottages. 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 Leeds City 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 Adel projects come up most often:

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