Drawings that turn a Hackney house into self-contained flats — units sized to space standards, separated for sound and fire, and drawn to Hackney 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.
Hackney Council granted 89% of the householder planning decisions it made in its latest published year — 2 points above the 87% England-wide householder average. Parapet-fronted terraces mean rear roof extensions are scrutinised harder than the concealed front slope suggests, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837) and Victorian (1837–1901) housing stock sets the design brief on most streets.
The permitted-development ceilings are fixed: 40m³ of new roof volume for a terraced loft and 50m³ for a semi or detached house under Class B, plus a 3m single-storey rear extension on a terrace or 4m on a detached house under Class A. Hackney carries at least one Article 4 direction, and conservation areas including De Beauvoir Town, Clapton Square and Stoke Newington Church Street remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Hackney is determined against an 8-week statutory target.
De Beauvoir Town (grid of early-Victorian villas inside a tightly protected conservation area), Stoke Newington (Georgian and Victorian frontages along Church Street with heavy heritage control), Clapton (Victorian terraces and squares around Clapton Square), London Fields (dense Victorian terraces framing the park), Dalston (mixed Victorian stock with warehouse conversions off the high street) and Shoreditch (former industrial and warehouse buildings turned residential) — these are the Hackney pockets our drawings cover most. Heritage designations here include De Beauvoir Town, Clapton Square, Stoke Newington Church Street, London Fields and Well Street Common. Hackney Council weighs each proposal against Hackney Local Plan 2033 (LP33) and the Development Management supplementary guidance, where warehouse conversions are read against the borough's employment-floorspace and character policies before residential gains are weighed. A large share of Hackney's terraces and warehouses are split into flats and maisonettes, none of which carry householder permitted-development rights.. On roofs the borough is London butterfly / valley roofs behind parapets and pitched slate roofs on the villas, over Georgian and early-Victorian terraces, later Victorian terraces and villas and warehouse and industrial conversions.
Splitting one dwelling into several is the most policy-heavy job a house takes on, and Hackney has the stock that invites it — the borough's Georgian and early-Victorian terraces, later Victorian terraces and villas and warehouse and industrial conversions 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, Hackney 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. Parapet-fronted terraces mean rear roof extensions are scrutinised harder than the concealed front slope suggests, which shapes what mix and layout will pass here.
Where the house sits in a conservation area — De Beauvoir Town, Clapton Square, Stoke Newington Church Street, London Fields and Well Street Common among Hackney'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. Hackney is one of London's most conservation-dense boroughs, and directions such as the one covering Stoke Newington strip out permitted-development rights for shopfronts, roof alterations and frontages, so nothing on those streets is automatic. 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 Hackney 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 Hackney 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 Hackney Council's real householder and residential decision record, drawn from official planning statistics and refreshed as new data lands. Hackney approves the large majority of householder applications, but the borough's dense web of conservation areas is the single biggest factor shaping what design will pass. 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 Hackney are the ones that treat the new homes as homes, not as the maximum number of doors that fit. Across De Beauvoir Town, Stoke Newington and Clapton, 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.
Warehouse conversions are read against the borough's employment-floorspace and character policies before residential gains are weighed. We design the mix to what Hackney 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 Hackney 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 | Hackney Council planning |
| Space standards | Minimum floor area per bedroom and bed space | National space standard | Hackney Council planning |
| Unit mix & amenity | Sensible flat sizes, light, outdoor space | Local housing policy | Hackney Council planning |
| Sound & fire separation | Part E acoustic and protected escape | Building regulations | Building control |
In conservation areas such as De Beauvoir Town and Clapton Square, external changes to a Hackney conversion — entrances, bin and bike stores — are assessed against the area's character.
A fixed process built around how Hackney Council judges conversions — most drawing sets are submission-ready within seven days of survey.
Send us your Hackney postcode and the building. We test how many units realistically fit at the space standard, confirm the mix Hackney 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 Hackney Council's conversion policy.
We lodge the application, manage validation and case-officer queries, and revise the drawings free until Hackney 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 Hackney 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 Hackney 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. Hackney Council will refuse units below the standard. We test how many compliant flats a Hackney 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 Hackney 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. Hackney 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 Hackney 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. Hackney Council is the decision-maker.
We price each Hackney 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 Hackney Council decides. Building-regs separation drawings and any council fee are quoted separately.
