Annexe and granny-flat drawings for Adel homes — designed to stay ancillary to the main house rather than become a separate dwelling, drawn to Leeds City Council's policies, delivered in days and revised free until your decision.
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.
Councils do not decide annexes on square metres. They decide whether, once built, the accommodation forms part of one planning unit with the main house or a second one beside it. Leeds City Council looks at whether the garden is shared or divided, whether the annexe has its own street access and address, whether the occupier could live there entirely independently, and whether the two households would function as one. That is the whole case, and it is made or lost on the layout.
Adel is largely 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, which shapes the realistic options: converting part of the existing house, extending it, or building a detached unit in the garden. A detached annexe can sometimes sit under Class E as an outbuilding incidental to the enjoyment of the dwellinghouse — but sleeping accommodation is generally not "incidental", so a garden annexe with a bedroom usually needs its own permission rather than relying on outbuilding rights.
In Adel's conservation areas — including Adel St John's and Weetwood — a garden building is also judged on its effect on the character of the area, which limits height and footprint before the use question is reached. 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.
An annexe almost always needs an application to Leeds City Council. Expect one where any of these apply:
We plan the annexe so its relationship to the main house is visible on the page — shared garden, connected access, a layout that reads as one household — and set out the case Leeds City Council has to test, rather than leaving the officer to assume the worst.
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. Annexe applications are decided on use as much as design, so the supporting case matters as much as the elevations.

Across Adel village, Long Causeway and Holt Park, the annexes that succeed keep one shared garden, take access past the main house rather than from the street, and are modest against the host building — single storey where the plot is overlooked, and set back from boundaries. On interwar and postwar detached and semi-detached houses, converting an integral garage or a rear ground floor is often approved more readily than a detached garden unit, because the ancillary relationship is self-evident.
Extensive green belt around Adel sharply limits the scale of extensions and new outbuildings. Where Leeds City Council grants permission, it commonly attaches a condition tying occupation of the annexe to the main dwelling. That condition is not a problem to be avoided — it is usually the mechanism that makes approval possible, and we draft the application on that basis rather than pretending the annexe is something it is not.
We draw annexes across Adel. A few of the areas where multigenerational schemes come up most often:

Three similar buildings, three different consents. This is what separates them.
| What you build | Planning status | Key test | What Leeds City Council checks |
|---|---|---|---|
| Garden room, no sleeping space | Often Class E permitted development | Incidental to the house | Height, footprint, boundary position |
| Annexe used by the household | Full application, usually with a tie condition | Ancillary use | Shared garden and access, layout |
| Self-contained unit, own access | New dwelling — full application | Separate planning unit | Policy on new homes, amenity, parking |
| Converted garage or ground floor | Often permitted, use still assessed | Whether use changes | Independence of the accommodation |
| Annexe on designated land | Full application | Designation | Character and appearance |
The ancillary/separate-dwelling distinction comes from section 55 of the Town and Country Planning Act 1990; outbuilding limits from the GPDO 2015, Schedule 2, Part 1, Class E.
A fixed process built around how Leeds City Council tests the use question as well as the design.
Tell us who the annexe is for and where it would sit on the plot. We confirm designation status and tell you honestly whether the scheme reads as ancillary or as a separate dwelling in Adel.
We measure the plot, the existing house and the access route, so the shared-garden and shared-access case can be drawn rather than asserted.
Chartered designers develop the annexe to your brief, with the layout, access and garden relationship arranged to support the ancillary case under Leeds City Council's policies.
We submit the application with a supporting statement on use, manage validation and case-officer queries, and revise free until Leeds City Council decides.
Almost always. Sleeping accommodation is generally not "incidental" to the enjoyment of a house, so it falls outside the outbuilding permitted-development right, and any annexe that could function independently raises a change-of-use question under section 55. In Adel we prepare a full application to Leeds City Council and make the ancillary case explicitly rather than hoping it is not asked.
A shared garden rather than a divided one, access through the main property rather than a separate street entrance, occupation by a member of the same household, and a physical and functional relationship with the main house. Leeds City Council weighs those together — no single feature decides it, but a separate front door and a fenced-off garden together usually settle it against you. This applies to your Adel address specifically.
Yes, subject to permission. A detached garden annexe is assessed on its scale against the plot, its effect on neighbours and the character of the area, and then on the use question. Keeping it single storey, set in from boundaries and served off the shared garden gives it the best prospect in Adel, particularly near designated areas such as Adel St John's and Weetwood. Leeds City Council is the decision-maker.
Commonly, yes — a condition tying occupation of the annexe to the main dwelling, so it cannot be sold or let separately. That is normally what makes approval possible, because it removes the concern that a new independent home is being created without going through housing policy. The condition runs with the land, so it matters at resale, and we explain the implications before you commit. This applies to your Adel address specifically. Leeds City Council is the decision-maker.
Yes. A new annexe is new habitable accommodation, so structure, fire escape, insulation and ventilation all apply, and a detached annexe close to a boundary raises fire-spread requirements as well. Planning and building control are separate consents with separate submissions — we prepare both so the approved design is the one that can actually be built. This applies to your Adel address specifically. Leeds City Council is the decision-maker.
A householder application runs to an eight-week statutory target; where the council treats the annexe as creating a new unit it becomes a minor application with a thirteen-week target instead. Which route applies depends on how the use is characterised, which is precisely why the ancillary case is worth making properly at the outset. This applies to your Adel address specifically. Leeds City Council is the decision-maker.
