Annexe and granny-flat drawings for Stoneygate homes — designed to stay ancillary to the main house rather than become a separate dwelling, drawn to Leicester City Council's policies, delivered in days and revised free until your decision.
Leicester City Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. Stoneygate is Leicester's best-preserved Victorian and Edwardian suburb, so extensions are judged against the character appraisal's protection of villa plots, boundary walls and mature trees, 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.
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. Stoneygate carries at least one Article 4 direction, and conservation areas including Stoneygate, Ashleigh Road and Knighton remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Stoneygate is determined against an 8-week statutory target.
London Road (the tree-lined approach fronted by substantial period villas), Ratcliffe Road (large detached houses in mature garden plots), Springfield Road (gothic and arts-and-crafts villas within the conservation area), Elms Road (handsome Edwardian houses close to the Ashleigh Road boundary), Knighton Park Road (villas edging Knighton Park and the parkland fringe) and St John's (the church quarter of Victorian merchant houses) — these are the Stoneygate pockets our drawings cover most. Heritage designations here include Stoneygate, Ashleigh Road, Knighton and New Walk. Leicester City Council weighs each proposal against the Leicester Local Plan and the Stoneygate Conservation Area Character Appraisal, where the HMO Article 4 Direction restricts subdivision of the large family houses into student lets and small HMOs. Several of the larger villas have been split into flats or mansion apartments, and converted flats carry no householder permitted-development rights.. On roofs the borough is steep gabled slate and clay-tile roofs with ornate ridge detail and hipped roofs on the larger detached villas, over grand Victorian and Edwardian villas on generous plots, arts-and-crafts and gothic-revival detached houses and later mansion flats and infill apartments.
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. Leicester 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.
Stoneygate is largely grand Victorian and Edwardian villas on generous plots, arts-and-crafts and gothic-revival detached houses and later mansion flats and infill apartments, 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 Stoneygate's conservation areas — including Stoneygate and Ashleigh Road — 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 2022 extension of Leicester's HMO Article 4 Direction pulled much of Stoneygate into the controlled area, so new houses in multiple occupation need planning permission alongside the conservation controls that already cover the suburb.
An annexe almost always needs an application to Leicester 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 Leicester City Council has to test, rather than leaving the officer to assume the worst.
Below is Leicester City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Leicester grants the large majority of householder applications, though in Stoneygate the conservation status of the villa suburb and pressure to subdivide big houses are the recurring constraints. Annexe applications are decided on use as much as design, so the supporting case matters as much as the elevations.

Across London Road, Ratcliffe Road and Springfield Road, 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 grand victorian and edwardian villas on generous plots, 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.
Stoneygate is Leicester's best-preserved Victorian and Edwardian suburb, so extensions are judged against the character appraisal's protection of villa plots, boundary walls and mature trees. Where Leicester 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 Stoneygate. 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 Leicester 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 Leicester 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 Stoneygate.
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 Leicester City Council's policies.
We submit the application with a supporting statement on use, manage validation and case-officer queries, and revise free until Leicester 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 Stoneygate we prepare a full application to Leicester 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. Leicester 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 Stoneygate 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 Stoneygate, particularly near designated areas such as Stoneygate and Ashleigh Road. Leicester 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 Stoneygate address specifically. Leicester 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 Stoneygate address specifically. Leicester 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 Stoneygate address specifically. Leicester City Council is the decision-maker.
