The full drawing set for a Westminster application — location and block plans, existing and proposed floor plans, elevations and sections, drawn to Westminster City 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.
Westminster City Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. Basement excavation is tightly policed on depth, garden coverage and construction impact given the density of listed and stucco stock, 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. Westminster carries at least one Article 4 direction, and conservation areas including Bayswater, Maida Vale and Pimlico remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Westminster is determined against an 8-week statutory target.
Bayswater (stucco terraces around leafy garden squares), Maida Vale (red-brick and stucco mansion blocks along wide avenues), Pimlico (Thomas Cubitt's uniform white stucco terraces), Marylebone (Georgian and Victorian terraces mixed with mansion flats), Belgravia (grand stucco terraces served by their own mews) and Queen's Park (the model-cottage streets of the Queen's Park Estate on the Westminster side) — these are the Westminster pockets our drawings cover most. Heritage designations here include Bayswater, Maida Vale, Pimlico, Marylebone and Queen's Park. Westminster City Council weighs each proposal against the Westminster City Plan and the Basements SPD, where mansard and roof extensions are steered by the roof-extension policy to sit within an unbroken terrace profile. Larger stucco houses in Bayswater and Marylebone are widely converted into flats, which carry no householder permitted-development rights.. On roofs the borough is mansard roofs to the stucco terraces and concealed butterfly roofs behind parapets, over stucco-fronted Georgian and Victorian terraces, purpose-built mansion flats and mews houses to the rear of the grand streets.
Whatever you are building, Westminster City 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. Westminster City Council assesses each proposal against the Westminster City Plan and the Basements 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 Westminster's stock, which runs to stucco-fronted Georgian and Victorian terraces, purpose-built mansion flats and mews houses to the rear of the grand streets, the same scheme is drawn differently to answer the concerns officers raise here. Basement excavation is tightly policed on depth, garden coverage and construction impact given the density of listed and stucco stock, so the pack is built to pre-empt exactly that.
Where the property sits in a conservation area — Bayswater, Maida Vale, Pimlico, Marylebone and Queen's Park among Westminster's — validation is stricter still, often demanding heritage detail and sometimes additional plans. The overwhelming majority of Westminster lies within a conservation area, and Article 4 directions across districts like Bayswater and Pimlico remove permitted-development rights on facades, roofs and windows. We confirm the designation before drawing so the pack meets the higher bar first time.

Westminster City 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 Westminster City 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 Westminster City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Westminster grants a high share of householder applications, though near-total conservation-area coverage and a restrictive basement regime are the constraints behind 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 — Westminster City 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 Westminster applications lose weeks. We draw to the checklist so this never happens.
Second is the planning judgement itself, once the pack is valid. Mansard and roof extensions are steered by the roof-extension policy to sit within an unbroken terrace profile. Across Bayswater, Maida Vale and Pimlico 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 Westminster neighbourhoods and property types we prepare drawings for most often:
Planning drawings for Bayswater's stucco terraces around leafy garden squares — scaled, validation-ready and drawn to Westminster City Council's guidance.
Planning drawings for Maida Vale's red-brick and stucco mansion blocks along wide avenues — scaled, validation-ready and drawn to Westminster City Council's guidance.
Planning drawings for Pimlico's Thomas Cubitt's uniform white stucco terraces — scaled, validation-ready and drawn to Westminster City Council's guidance.
Planning drawings for Marylebone's Georgian and Victorian terraces mixed with mansion flats — scaled, validation-ready and drawn to Westminster City Council's guidance.
Planning drawings for Belgravia's grand stucco terraces served by their own mews — scaled, validation-ready and drawn to Westminster City Council's guidance.
Planning drawings for Queen's Park's the model-cottage streets of the Queen's Park Estate on the Westminster side — scaled, validation-ready and drawn to Westminster City Council's guidance.
The route decides what Westminster City Council needs and how long it takes. This is how the common Westminster 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 Bayswater and Maida Vale, 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 Westminster City Council's checklist.
We lodge the application on the Planning Portal, manage validation and case-officer queries, and revise the drawings free until Westminster City Council issues its decision.
Westminster City 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. Westminster City 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 Westminster City 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 Westminster City 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 Westminster City 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 Bayswater and Maida Vale, permitted-development rights are often removed, so a full application may be needed after all — we confirm which before you commit.
We price each Westminster 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. It covers the full validation pack with free revisions until Westminster City Council decides. The Westminster City Council application fee is separate and paid to the council.
