The full drawing set for a Lambeth application — location and block plans, existing and proposed floor plans, elevations and sections, drawn to Lambeth Council's validation checklist so the pack is accepted first time, delivered in days and revised free until your decision, with a free approval-odds check first.
Lambeth Council granted 89% of the householder planning decisions it made in its latest published year — 2 points above the 87% England-wide householder average. The loss of family houses to further flat conversion is resisted and frequently the deciding issue, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837), 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. Lambeth carries at least one Article 4 direction, and conservation areas including Clapham Old Town, Stockwell Park and Angell Town remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Lambeth is determined against an 8-week statutory target.
Clapham (Georgian and Victorian terraces around the Old Town and Common), Brixton (Victorian terraces heavily subdivided into flats), Stockwell (Georgian and Victorian streets around Stockwell Park), Herne Hill (Victorian villas and terraces on the Dulwich fringe), Streatham (Edwardian terraces and mansion blocks along the high road) and Kennington (Georgian and Regency terraces near the river) — these are the Lambeth pockets our drawings cover most. Heritage designations here include Clapham Old Town, Stockwell Park, Angell Town, Herne Hill and Leigham Court Estate. Lambeth Council weighs each proposal against Lambeth Local Plan and the council's Alterations and Extensions SPD, where mansards and roof additions on stucco-fronted terraces are measured against whatever original roofline survives on the street. Much of Brixton, Clapham and Stockwell is already converted flats and maisonettes, which hold no householder permitted-development rights.. On roofs the borough is butterfly and valley roofs behind the terrace parapets and mansard and pitched roofs on the taller stucco streets, over Georgian and Victorian terraces, converted flats and maisonettes and purpose-built mansion blocks and estates.
Whatever you are building, Lambeth Council decides it from the same core set. A location plan at 1:1250 fixes the site on the map with the red-line boundary; a block plan at 1:500 shows the property in its plot; then existing and proposed floor plans and elevations at 1:100 or 1:50 show the house as it is and as it will be. Larger schemes add a section and, where policy requires, a design and access statement. Miss one and the application is returned invalid before an officer has looked at it.
The drawings are also the argument. Lambeth Council assesses each proposal against Lambeth Local Plan and the council's Alterations and Extensions SPD, and the elevations are where the case is won or lost — ridge and eaves heights, window positions, materials and how the change reads from the street. On Lambeth's stock, which runs to Georgian and Victorian terraces, converted flats and maisonettes and purpose-built mansion blocks and estates, the same scheme is drawn differently to answer the concerns officers raise here. The loss of family houses to further flat conversion is resisted and frequently the deciding issue, so the pack is built to pre-empt exactly that.
Where the property sits in a conservation area — Clapham Old Town, Stockwell Park, Angell Town, Herne Hill and Leigham Court Estate among Lambeth's — validation is stricter still, often demanding heritage detail and sometimes additional plans. Alongside the controls in conservation areas such as Clapham Old Town, Lambeth runs a borough-wide Article 4 direction removing permitted-development rights for small shared houses, pulling many HMO changes into the application system. We confirm the designation before drawing so the pack meets the higher bar first time.

Lambeth Council validates against a published checklist before it assesses anything. A typical householder application needs each of these, correctly scaled and labelled:
We draw the complete set — location and block plans, existing and proposed plans, elevations and any section — to Lambeth Council's checklist, then lodge it on the Planning Portal, manage validation and answer case-officer queries so the application is decided on its merits, not bounced on a technicality.
Below is Lambeth Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Lambeth grants a high proportion of householder applications, but with so much of its stock already split into flats, protecting the remaining family houses is what shapes most refusals. A complete, correctly scaled pack that answers those concerns on the elevations is validated faster and refused less often than one that leaves them for the officer to raise.

Two different things sink an application, and they happen at two different stages. First is validation: a missing block plan, an unscaled elevation, no red line, no north point — Lambeth Council returns the whole submission and the clock never starts. Getting the pack right at this stage is purely mechanical, and it is where a lot of self-submitted Lambeth applications lose weeks. We draw to the checklist so this never happens.
Second is the planning judgement itself, once the pack is valid. Mansards and roof additions on stucco-fronted terraces are measured against whatever original roofline survives on the street. Across Clapham, Brixton and Stockwell the recurring refusals are about scale, overlooking and how the proposal sits against its neighbours — all of which are settled on the drawings. We draw the scheme to answer them before submission rather than after a refusal.

The application pack is the same discipline whatever the project. A few of the Lambeth neighbourhoods and property types we prepare drawings for most often:
Planning drawings for Clapham's Georgian and Victorian terraces around the Old Town and Common — scaled, validation-ready and drawn to Lambeth Council's guidance.
Planning drawings for Brixton's Victorian terraces heavily subdivided into flats — scaled, validation-ready and drawn to Lambeth Council's guidance.
Planning drawings for Stockwell's Georgian and Victorian streets around Stockwell Park — scaled, validation-ready and drawn to Lambeth Council's guidance.
Planning drawings for Herne Hill's Victorian villas and terraces on the Dulwich fringe — scaled, validation-ready and drawn to Lambeth Council's guidance.
Planning drawings for Streatham's Edwardian terraces and mansion blocks along the high road — scaled, validation-ready and drawn to Lambeth Council's guidance.
Planning drawings for Kennington's Georgian and Regency terraces near the river — scaled, validation-ready and drawn to Lambeth Council's guidance.
The route decides what Lambeth Council needs and how long it takes. This is how the common Lambeth routes compare.
| Route | When it applies | Core drawings | Typical decision |
|---|---|---|---|
| Householder application | Extensions and alterations to a single house | Location, block, existing & proposed plans and elevations | About 8 weeks |
| Full application | Flats, new units, changes of use | As householder plus site plan and often a section | 8–13 weeks |
| Lawful development certificate | Confirming a scheme is permitted development | Existing & proposed plans and elevations to prove PD limits | About 8 weeks |
| Prior approval | Larger single-storey rear extensions | Plans and elevations plus neighbour notification | About 6 weeks |
In a conservation area such as Clapham Old Town and Stockwell Park, householder permitted-development rights are often restricted, so a full application and heritage detail may be required.

We measure the property and plot so the existing plans and elevations are accurate to the millimetre — the base every proposed drawing and every officer judgement is built on.
Chartered designers produce the full validation pack — location and block plans, existing and proposed plans, elevations, any section and a design and access statement — drawn to Lambeth Council's checklist.
We lodge the application on the Planning Portal, manage validation and case-officer queries, and revise the drawings free until Lambeth Council issues its decision.
Lambeth Council validates a householder application against a set list: a location plan at 1:1250 with a red-line boundary, a block plan at 1:500, and existing and proposed floor plans and elevations at 1:100 or 1:50, each with a scale bar and north point. Larger schemes and most conservation-area work also need a design and access statement. If any of these is missing or unscaled the application is returned invalid before it is assessed.
Almost always because the drawing pack is incomplete or wrongly scaled — a missing block plan, an elevation with no scale, no red line on the location plan, no north point. Lambeth Council checks the pack against its validation list before an officer ever assesses the scheme, so these purely technical gaps cost weeks. Drawing to the checklist from the outset is the simplest way to avoid a return.
Yes. We prepare the full drawing set, lodge it on the Planning Portal on your behalf, pay the Lambeth Council fee where you prefer us to, and then manage validation and case-officer questions through to the decision. You get the reference number and updates without dealing with the portal or the council yourself.
A householder application is a statutory eight weeks from validation, and a full application eight to thirteen weeks depending on scale. The date that matters is validation, not submission — an invalid pack never starts the clock. Because we draw to Lambeth Council's checklist the application validates quickly, so the statutory period begins without the delay a returned pack causes.
You do not strictly need a planning application, but scaled existing and proposed drawings are still worth having: a lawful development certificate from Lambeth Council proves the scheme is permitted development, which lenders and buyers increasingly ask for, and your builder needs the drawings to price and build. In a conservation area such as Clapham Old Town and Stockwell Park, permitted-development rights are often removed, so a full application may be needed after all — we confirm which before you commit.
We price each Lambeth job individually — the scope of the survey and the size of the drawing set vary from a simple rear extension to a whole-house scheme — and send a fixed, no-obligation quote within one working day.
