The full drawing set for a Croydon application — location and block plans, existing and proposed floor plans, elevations and sections, drawn to Croydon 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.
Croydon Council granted 84% of the householder planning decisions it made in its latest published year — 3 points below the 87% England-wide householder average. After a wave of garden-grab and back-land intensification, the council reversed course and tightened controls to guard family housing and suburban grain, 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 Croydon Council needs a full application. Croydon carries at least one Article 4 direction, and conservation areas including Addiscombe (Canning and Clyde Roads), Upper Norwood Triangle and Park Hill remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Croydon is determined against an 8-week statutory target.
Addiscombe (Victorian and Edwardian terraces east of the town centre), Upper Norwood (hilltop Victorian villas around the Triangle), South Norwood (dense Victorian terraces near the lakes), Waddon (interwar semi-detached housing toward the Wandle), Sanderstead (interwar and detached homes on the southern downs) and Thornton Heath (long Victorian terraces off the high street) — these are the Croydon pockets our drawings cover most. Heritage designations here include Addiscombe (Canning and Clyde Roads), Upper Norwood Triangle, Park Hill, South Norwood and Sanderstead. Croydon Council weighs each proposal against Croydon Local Plan and the Suburban Design Guide SPD, where hip-to-gable and roof changes on interwar semis are read against the symmetry of the matched pair. Central Croydon, Addiscombe and Thornton Heath hold pockets of converted flats and small shared houses that sit outside householder permitted-development rights.. On roofs the borough is hipped roofs on the interwar semis and pitched and gabled roofs on the Victorian terraces, over Victorian and Edwardian terraces, interwar semi-detached houses and postwar suburban estates.
Whatever you are building, Croydon 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. Croydon Council assesses each proposal against Croydon Local Plan and the Suburban Design Guide 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 Croydon's stock, which runs to Victorian and Edwardian terraces, interwar semi-detached houses and postwar suburban estates, the same scheme is drawn differently to answer the concerns officers raise here. After a wave of garden-grab and back-land intensification, the council reversed course and tightened controls to guard family housing and suburban grain, so the pack is built to pre-empt exactly that.
Where the property sits in a conservation area — Addiscombe (Canning and Clyde Roads), Upper Norwood Triangle, Park Hill, South Norwood and Sanderstead among Croydon's — validation is stricter still, often demanding heritage detail and sometimes additional plans. Croydon has made Article 4 directions removing permitted-development rights, covering small HMOs across parts of the borough and works in conservation areas such as the Canning and Clyde Roads area of Addiscombe. We confirm the designation before drawing so the pack meets the higher bar first time.

Croydon 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 Croydon 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 Croydon Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Croydon approves a solid but more measured share of householder applications, having stepped back from its earlier drive for suburban intensification to protect family housing and the rhythm of its semi-detached streets. 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 — Croydon 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 Croydon applications lose weeks. We draw to the checklist so this never happens.
Second is the planning judgement itself, once the pack is valid. Hip-to-gable and roof changes on interwar semis are read against the symmetry of the matched pair. Across Addiscombe, Upper Norwood and South Norwood 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 Croydon neighbourhoods and property types we prepare drawings for most often:
Planning drawings for Addiscombe's Victorian and Edwardian terraces east of the town centre — scaled, validation-ready and drawn to Croydon Council's guidance.
Planning drawings for Upper Norwood's hilltop Victorian villas around the Triangle — scaled, validation-ready and drawn to Croydon Council's guidance.
Planning drawings for South Norwood's dense Victorian terraces near the lakes — scaled, validation-ready and drawn to Croydon Council's guidance.
Planning drawings for Waddon's interwar semi-detached housing toward the Wandle — scaled, validation-ready and drawn to Croydon Council's guidance.
Planning drawings for Sanderstead's interwar and detached homes on the southern downs — scaled, validation-ready and drawn to Croydon Council's guidance.
Planning drawings for Thornton Heath's long Victorian terraces off the high street — scaled, validation-ready and drawn to Croydon Council's guidance.
The route decides what Croydon Council needs and how long it takes. This is how the common Croydon 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 Addiscombe (Canning and Clyde Roads) and Upper Norwood Triangle, householder permitted-development rights are often restricted, so a full application and heritage detail may be required.

Send us your Croydon postcode and what you want to build. We confirm your conservation and Article 4 status, tell you which application route applies, and score your odds against live Croydon Council decisions.
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 Croydon Council's checklist.
We lodge the application on the Planning Portal, manage validation and case-officer queries, and revise the drawings free until Croydon Council issues its decision.
Croydon 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. Croydon 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 Croydon 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 Croydon 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 Croydon 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 Addiscombe (Canning and Clyde Roads) and Upper Norwood Triangle, permitted-development rights are often removed, so a full application may be needed after all — we confirm which before you commit.
We price each Croydon 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.
