Drawings that turn a Woking house into self-contained flats — units sized to space standards, separated for sound and fire, and drawn to Woking Borough Council's conversion policy so the change of use is approved, delivered in days and revised free until your decision, with a free feasibility check first.
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.
Splitting one dwelling into several is the most policy-heavy job a house takes on, and Woking has the stock that invites it — the borough's 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 include the large period houses and mansion-block flats that convert well, and streets already part-converted set the pattern. But because you are creating new homes, Woking Borough Council assesses the scheme against its housing and conversion policies, not just its extension guidance, so the internal layout carries planning weight it never would in a single house.
The layout has to satisfy several standards together. Each flat must meet the nationally described space standard for its number of bedrooms and bed spaces, with adequate light and outlook; the mix the council will accept is often set by policy, with some boroughs resisting too many small units or requiring a family-sized flat; and every unit needs its own amenity, plus cycle and refuse storage that works for the whole building. Metropolitan Green Belt covers roughly three-fifths of the borough, one of the highest shares in England, forcing growth onto the urban core, which shapes what mix and layout will pass here.
Where the house sits in a conservation area — Old Woking, Horsell, Hook Heath, Mount Hermon, St Johns and Byfleet among Woking's — external changes are read hard: new entrances, bin and bike stores, meter boxes and any subdivision visible from the street all have to respect the area's character. 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. We resolve the frontage and access before the internal layout is fixed.
Yes — a house-to-flats conversion is a change of use and always needs a full application to Woking Borough Council. The scheme has to satisfy each of these, and the drawings are where each is proven:
We lay out flats that meet the space standard, plan the sound and fire separation, and solve the entrances, bins and bike stores — then draw the change-of-use application to Woking Borough Council's conversion policy so the scheme is judged on a complete proposal, not bounced for a unit that is too small or a layout that cannot be separated.
Below is Woking Borough Council's real householder and residential 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. Conversions are judged harder than extensions because they create new homes, so a scheme that proves space, mix and separation upfront is decided far more smoothly than one that leaves the officer to find the gaps.

The conversions that pass in Woking are the ones that treat the new homes as homes, not as the maximum number of doors that fit. Across Woking town centre, Horsell and Old Woking, the approved schemes give each flat a proper layout at or above the space standard, a sensible mix rather than a stack of studios, and amenity, bin and cycle provision that does not wreck the frontage. Overcrowding the building is the quickest route to refusal, and it rarely adds the value it promises.
Consequent town-centre densification through tall flatted schemes sits in tension with protected village character at Horsell, Old Woking and Pyrford. We design the mix to what Woking Borough Council will accept, prove each unit meets the standard on the plan, and coordinate the planning layout with the sound and fire separation from the outset — so the scheme that gets permission is the same one building control can sign off, not a layout that has to be torn up at the next stage.
We convert houses and reconfigure flats on the period streets and mansion blocks across the borough. A few of the Woking neighbourhoods where conversions come up most often:

A conversion is judged on planning and building standards together. This is what each requires and who checks it.
| Requirement | What it means | Set by | Checked at |
|---|---|---|---|
| Change of use | Creating separate self-contained units | Planning policy | Woking Borough Council planning |
| Space standards | Minimum floor area per bedroom and bed space | National space standard | Woking Borough Council planning |
| Unit mix & amenity | Sensible flat sizes, light, outdoor space | Local housing policy | Woking Borough Council planning |
| Sound & fire separation | Part E acoustic and protected escape | Building regulations | Building control |
In conservation areas such as Old Woking and Horsell, external changes to a Woking conversion — entrances, bin and bike stores — are assessed against the area's character.
A fixed process built around how Woking Borough Council judges conversions — most drawing sets are submission-ready within seven days of survey.
Send us your Woking postcode and the building. We test how many units realistically fit at the space standard, confirm the mix Woking Borough Council is likely to accept, and flag conservation, Article 4 and access constraints before you commit.
We measure the building accurately, because a conversion lives or dies on floor areas — every flat has to be proven against the space standard on a plan that matches the real property.
We design the flats to the space standard, coordinate the sound and fire separation and the entrances, bins and cycle stores, and draw the full change-of-use application to Woking Borough Council's conversion policy.
We lodge the application, manage validation and case-officer queries, and revise the drawings free until Woking Borough Council issues its decision.
Always. Splitting one house into two or more self-contained flats is a change of use, which is never permitted development, so a full application to Woking Borough Council is required. The council assesses the unit sizes, the mix and the amenity against its housing policy, as well as any external changes. A Woking conversion is judged more closely than an extension precisely because it creates new homes.
Each flat must meet the nationally described space standard, which sets a minimum floor area by the number of bedrooms and bed spaces — a one-bed one-person flat starts at 37–39 square metres, and larger units scale up from there. Woking Borough Council will refuse units below the standard. We test how many compliant flats a Woking building genuinely holds at feasibility, rather than drawing undersized units that cannot be approved.
Once you create separate units, building control requires Part E acoustic separation between them — the floors and party walls must be built or upgraded to resist airborne and impact sound — and a protected means of escape so each flat can be left safely in a fire. These are checked by Woking Borough Council's building control, separately from planning. We plan the separation into the layout from the start, so the planning design and the building-regs build are the same scheme.
Not necessarily. Many boroughs set policy on the mix — resisting schemes that are all studios or one-beds, and sometimes requiring a family-sized flat — to keep a range of homes. Woking Borough Council applies its own housing policy to a conversion, so the profitable-looking stack of small units is often the one that gets refused. We design the mix to what the borough will actually accept before drawing the application.
Usually yes. Once the Woking building is flats, each unit is normally sold or let on a lease, and a Land Registry-compliant lease plan is needed to define its extent. The measured survey behind the conversion drawings is the ideal base for those lease plans, so the same accurate record serves the planning application, the building-regs layout and the leases without measuring the building twice. Woking Borough Council is the decision-maker.
We price each Woking conversion on the number of units and the building's size and complexity, and send a fixed, no-obligation quote within one working day. It covers the feasibility, the change-of-use application drawings and free revisions until Woking Borough Council decides. Building-regs separation drawings and any council fee are quoted separately.
