Annexe and granny-flat drawings for Woking homes — designed to stay ancillary to the main house rather than become a separate dwelling, drawn to Woking Borough Council's policies, delivered in days and revised free until your decision.
Woking Borough Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. Metropolitan Green Belt covers roughly three-fifths of the borough, one of the highest shares in England, forcing growth onto the urban core, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), Edwardian (1901–1910), interwar (1918–1939) and postwar (1945–1970) 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. Woking carries at least one Article 4 direction, and conservation areas including Old Woking, Horsell and Hook Heath remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Woking is determined against an 8-week statutory target.
Woking town centre (dense modern flatted and commercial regeneration), Horsell (historic village character beside Horsell Common), Old Woking (the historic parish core with a conservation area), Hook Heath (affluent large detached houses on wooded plots), Knaphill (postwar and interwar suburban semis to the west) and West Byfleet (village-character commuter settlement to the north-east) — these are the Woking pockets our drawings cover most. Heritage designations here include Old Woking, Horsell, Hook Heath, Mount Hermon, St Johns and Byfleet. Woking Borough Council weighs each proposal against the Woking Core Strategy (adopted 2012) and Site Allocations DPD (adopted 2021), where consequent town-centre densification through tall flatted schemes sits in tension with protected village character at Horsell, Old Woking and Pyrford. Converted and purpose-built flats are common and growing, heavily concentrated in the town centre, and hold no householder permitted-development rights.. On roofs the borough is pitched gabled and hipped tiled roofs on the villas and semis and steep tile-hung and gabled roofs on the affluent detached houses, over Victorian and Edwardian villas around Woking, Horsell and Maybury built after the 1838 railway, large detached stockbroker-belt houses on wooded plots at Hook Heath and Pyrford, interwar and postwar semi-detached and terraced commuter suburbia and high-density modern flats in the town centre.
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. Woking Borough 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.
Woking is largely Victorian and Edwardian villas around Woking, Horsell and Maybury built after the 1838 railway, large detached stockbroker-belt houses on wooded plots at Hook Heath and Pyrford, interwar and postwar semi-detached and terraced commuter suburbia and high-density modern flats in the town centre, 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 Woking's conservation areas — including Old Woking and Horsell — 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. Woking uses Article 4(2) directions within its conservation areas to remove specified permitted-development rights, so minor alterations to houses in areas such as Old Woking and Mount Hermon need planning consent.
An annexe almost always needs an application to Woking Borough 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 Woking Borough Council has to test, rather than leaving the officer to assume the worst.
Below is Woking Borough Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Woking is among the more restrictive commuter authorities, with dominant Green Belt and heathland designations the reason its countryside grant rate runs below the national average even as urban householder work fares better. Annexe applications are decided on use as much as design, so the supporting case matters as much as the elevations.

Across Woking town centre, Horsell and Old Woking, 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 victorian and edwardian villas around woking, horsell and maybury built after the 1838 railway, 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.
Metropolitan Green Belt covers roughly three-fifths of the borough, one of the highest shares in England, forcing growth onto the urban core. Where Woking Borough 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 Woking. 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 Woking Borough 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 Woking Borough 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 Woking.
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 Woking Borough Council's policies.
We submit the application with a supporting statement on use, manage validation and case-officer queries, and revise free until Woking Borough 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 Woking we prepare a full application to Woking Borough 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. Woking Borough 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.
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 Woking, particularly near designated areas such as Old Woking and Horsell. Woking Borough 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 Woking address specifically. Woking Borough 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 Woking address specifically. Woking Borough 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 Woking address specifically. Woking Borough Council is the decision-maker.
