Drawings that turn a Reigate & Banstead house into self-contained flats — units sized to space standards, separated for sound and fire, and drawn to Reigate & Banstead 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.
Reigate & Banstead Borough Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. A double landscape constraint applies in the south, combining Metropolitan Green Belt with the Surrey Hills Area of Outstanding Natural Beauty, 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.
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 Reigate & Banstead Borough Council needs a full application. Reigate & Banstead carries at least one Article 4 direction, and conservation areas including Reigate, Redhill and Banstead Village remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Reigate & Banstead is determined against an 8-week statutory target.
Reigate (historic market town with Victorian and Edwardian conservation cores), Redhill (a Victorian railway-junction town with postwar and new-build regeneration), Banstead (low-density 1930s interwar semis around a village core), Horley (a southern town of postwar and ongoing new-build estates), Merstham (Victorian terraces alongside the postwar New Merstham estates) and Nutfield (a rural village in the Green Belt and Surrey Hills setting) — these are the Reigate & Banstead pockets our drawings cover most. Heritage designations here include Reigate, Redhill, Banstead Village, Reigate Heath, Nutfield and Merstham. Reigate & Banstead Borough Council weighs each proposal against the Reigate & Banstead Core Strategy (adopted 2014) and Development Management Plan (adopted 2019), where the 2019 Development Management Plan released nine Green Belt sites as sustainable urban extensions for around 845 homes, a notable managed release. Flats are a meaningful share of stock in the Redhill and Reigate town centres and at Merstham, and converted flats hold no householder permitted-development rights.. On roofs the borough is pitched clay and concrete-tile gabled and hipped roofs on the interwar semis and steeper tiled roofs on the Victorian mansions of Reigate Hill and Wray Common, over Victorian and Edwardian streets in Reigate and around Redhill's railway junction, abundant low-density 1930s interwar semis in Banstead, postwar and modern estate housing in Redhill, Horley and Merstham and village vernacular in the rural Green Belt and Surrey Hills settlements.
Splitting one dwelling into several is the most policy-heavy job a house takes on, and Reigate & Banstead has the stock that invites it — the borough's Victorian and Edwardian streets in Reigate and around Redhill's railway junction, abundant low-density 1930s interwar semis in Banstead, postwar and modern estate housing in Redhill, Horley and Merstham and village vernacular in the rural Green Belt and Surrey Hills settlements 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, Reigate & Banstead 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. A double landscape constraint applies in the south, combining Metropolitan Green Belt with the Surrey Hills Area of Outstanding Natural Beauty, which shapes what mix and layout will pass here.
Where the house sits in a conservation area — Reigate, Redhill, Banstead Village, Reigate Heath, Nutfield and Merstham among Reigate & Banstead'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. An Article 4 direction in force from February 2026 removes the permitted right to change ground-floor commercial units to residential across the borough's town and local centres, protecting retail and services frontages. 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 Reigate & Banstead 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 Reigate & Banstead 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 Reigate & Banstead Borough Council's real householder and residential decision record, drawn from official planning statistics and refreshed as new data lands. Reigate & Banstead grants a fair share of householder applications broadly at the national norm, higher than the most heavily green-belted Surrey neighbours, with the AONB and Green Belt the main constraints in the south. 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 Reigate & Banstead are the ones that treat the new homes as homes, not as the maximum number of doors that fit. Across Reigate, Redhill and Banstead, 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.
The 2019 Development Management Plan released nine Green Belt sites as sustainable urban extensions for around 845 homes, a notable managed release. We design the mix to what Reigate & Banstead 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 Reigate & Banstead 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 | Reigate & Banstead Borough Council planning |
| Space standards | Minimum floor area per bedroom and bed space | National space standard | Reigate & Banstead Borough Council planning |
| Unit mix & amenity | Sensible flat sizes, light, outdoor space | Local housing policy | Reigate & Banstead Borough Council planning |
| Sound & fire separation | Part E acoustic and protected escape | Building regulations | Building control |
In conservation areas such as Reigate and Redhill, external changes to a Reigate & Banstead conversion — entrances, bin and bike stores — are assessed against the area's character.
A fixed process built around how Reigate & Banstead Borough Council judges conversions — most drawing sets are submission-ready within seven days of survey.
Send us your Reigate & Banstead postcode and the building. We test how many units realistically fit at the space standard, confirm the mix Reigate & Banstead 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 Reigate & Banstead Borough Council's conversion policy.
We lodge the application, manage validation and case-officer queries, and revise the drawings free until Reigate & Banstead 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 Reigate & Banstead 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 Reigate & Banstead 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. Reigate & Banstead Borough Council will refuse units below the standard. We test how many compliant flats a Reigate & Banstead 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 Reigate & Banstead 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. Reigate & Banstead 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 Reigate & Banstead 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. Reigate & Banstead Borough Council is the decision-maker.
