The full drawing set for a Dorset application — location and block plans, existing and proposed floor plans, elevations and sections, drawn to Dorset 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.
Dorset Council granted 95% of the householder planning decisions it made in its latest published year — 8 points above the 87% England-wide householder average. Dorset contains Abbotsbury Conservation Area, Acton Conservation Area 1, Acton Conservation Area 2 conservation areas (Abbotsbury Conservation Area designated 1971), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) and postwar (1945–1970) 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. Dorset carries at least one Article 4 direction, and conservation areas including Abbotsbury Conservation Area, Acton Conservation Area 1 and Acton Conservation Area 2 remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Dorset is determined against an 8-week statutory target.
Abbotsbury (conservation area designated in 1971), Acton Conservation Area 1 (conservation area designated in 1975), Acton Conservation Area 2 (conservation area designated in 1975), Almer (conservation area designated in 1992), Alton Pancras (conservation area designated in 1990), Ashmore (conservation area designated in 1993), Beaminster Conservation Area 1 (conservation area designated in 1969), Beaminster Conservation Area 2 (conservation area designated in 1994), Beacon (ward of Dorset), Beaminster (ward of Dorset), Blackmore Vale (ward of Dorset), Blandford (ward of Dorset), Chalk Valleys (ward of Dorset), Charminster St Mary's (ward of Dorset), Chickerell (ward of Dorset) and Cranborne & Alderholt (ward of Dorset) — these are the Dorset pockets our drawings cover most. Heritage designations here include Abbotsbury Conservation Area, Acton Conservation Area 1, Acton Conservation Area 2, Almer Conservation Area, Alton Pancras Conservation Area, Ashmore Conservation Area, Beaminster Conservation Area 1 and Beaminster Conservation Area 2. Dorset Council weighs each proposal against Dorset Council's adopted local plan and its householder design guidance, where the 138,990 homes here are 21% pre-1900, 7% 1973-1982, 7% 1965-1972, which is what sets the realistic roof and rear-projection options. On roofs the borough is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow trussed roofs typical of 1970s building, over Victorian and earlier houses (21% of 138,990 homes), 1970s and early-1980s houses (7%) and late-1960s and early-1970s houses (7%).
What is permitted in Dorset turns on designation first, so that is where we start: Abbotsbury (conservation area designated in 1971), Acton Conservation Area 1 (conservation area designated in 1975), Acton Conservation Area 2 (conservation area designated in 1975), Almer (conservation area designated in 1992), Alton Pancras (conservation area designated in 1990), Ashmore (conservation area designated in 1993), Beaminster Conservation Area 1 (conservation area designated in 1969) and Beaminster Conservation Area 2 (conservation area designated in 1994). Inside those boundaries permitted development is curtailed and Dorset Council assesses materials, window detail and roof form against the area's own appraisal, so a scheme that would be waved through two streets away can need a full application here.
Beyond the designated areas, Dorset takes in Beacon, Beaminster, Blackmore Vale, Blandford, Chalk Valleys, Charminster St Mary's, Chickerell and Cranborne & Alderholt. Dorset Council has 77 recorded Article 4 directions — check the address before assuming PD applies in the district.
On stock, Dorset is Victorian and earlier houses (21% of 138,990 homes), 1970s and early-1980s houses (7%) and late-1960s and early-1970s houses (7%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow trussed roofs typical of 1970s building govern what a loft or rear projection can realistically be. Dorset Council decided 1,261 householder applications in the latest published year and granted 95%, with 78% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Dorset runs pre-1900 3% (190 homes), 1900-1918 0% (30 homes), 1919-1929 0% (10 homes), 1930-1939 6% (350 homes), 1945-1954 3% (170 homes), 1955-1964 30% (1,850 homes), 1965-1972 33% (1,990 homes), 1973-1982 4% (260 homes), 1983-1992 5% (310 homes), 1993-1999 4% (220 homes) and 2000-2008 3% (170 homes). That distribution is why pre-1900 detailing dominates the drawings here, and it is measured from council-tax records rather than assumed from the street name.
Dorset Council also decides for Beacon, Beaminster, Blackmore Vale, Blandford, Chalk Valleys, Charminster St Mary's, Chickerell and Cranborne & Alderholt, so a decision in Dorset sits inside a wider pattern of decisions we track across the same authority — useful when an officer cites a precedent from the next area over.
The Article 4 directions recorded for this council include 1-3 The Lane, Kingston, Corfe Castle, 10 Cornwall Road, Swanage, 6 Burlington Road, Swanage and Avon Castle & Matchams Park Estate. Each removes a specific permitted-development right inside its own boundary, which is why the check is done on the address rather than on the town.

Whatever you are building, Dorset 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. Dorset Council assesses each proposal against Dorset Council's adopted local plan and its householder design guidance, 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 Dorset's stock, which runs to Victorian and earlier houses (21% of 138,990 homes), 1970s and early-1980s houses (7%) and late-1960s and early-1970s houses (7%), the same scheme is drawn differently to answer the concerns officers raise here. Dorset contains Abbotsbury Conservation Area, Acton Conservation Area 1, Acton Conservation Area 2 conservation areas (Abbotsbury Conservation Area designated 1971), so materials, fenestration and roof form are assessed against the appraisal, so the pack is built to pre-empt exactly that.
Where the property sits in a conservation area — Abbotsbury Conservation Area, Acton Conservation Area 1, Acton Conservation Area 2, Almer Conservation Area, Alton Pancras Conservation Area, Ashmore Conservation Area, Beaminster Conservation Area 1 and Beaminster Conservation Area 2 among Dorset's — validation is stricter still, often demanding heritage detail and sometimes additional plans. Dorset Council has 77 recorded Article 4 directions — check the address before assuming PD applies in the district. We confirm the designation before drawing so the pack meets the higher bar first time.
Dorset 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 Dorset 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 Dorset Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Dorset Council granted 95% of 1,261 householder decisions in the year to 31 March 2026, 78% of them inside eight weeks. 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 — Dorset 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 Dorset applications lose weeks. We draw to the checklist so this never happens.
Second is the planning judgement itself, once the pack is valid. The 138,990 homes here are 21% pre-1900, 7% 1973-1982, 7% 1965-1972, which is what sets the realistic roof and rear-projection options. Across Abbotsbury, Acton Conservation Area 1 and Acton Conservation Area 2 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 Dorset neighbourhoods and property types we prepare drawings for most often:
Planning drawings for Abbotsbury's conservation area designated in 1971 — scaled, validation-ready and drawn to Dorset Council's guidance.
Planning drawings for Acton Conservation Area 1's conservation area designated in 1975 — scaled, validation-ready and drawn to Dorset Council's guidance.
Planning drawings for Acton Conservation Area 2's conservation area designated in 1975 — scaled, validation-ready and drawn to Dorset Council's guidance.
Planning drawings for Almer's conservation area designated in 1992 — scaled, validation-ready and drawn to Dorset Council's guidance.
Planning drawings for Alton Pancras's conservation area designated in 1990 — scaled, validation-ready and drawn to Dorset Council's guidance.
Planning drawings for Ashmore's conservation area designated in 1993 — scaled, validation-ready and drawn to Dorset Council's guidance.
The route decides what Dorset Council needs and how long it takes. This is how the common Dorset 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 Abbotsbury Conservation Area and Acton Conservation Area 1, householder permitted-development rights are often restricted, so a full application and heritage detail may be required.
A fixed process built around how Dorset Council validates and decides — most drawing sets are submission-ready within seven days of survey.
Send us your Dorset 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 Dorset 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 Dorset Council's checklist.
We lodge the application on the Planning Portal, manage validation and case-officer queries, and revise the drawings free until Dorset Council issues its decision.
Dorset 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. Dorset 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 Dorset 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 Dorset 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 Dorset 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 Abbotsbury Conservation Area and Acton Conservation Area 1, permitted-development rights are often removed, so a full application may be needed after all — we confirm which before you commit.
We price each Dorset 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 Dorset Council decides. The Dorset Council application fee is separate and paid to the council. Call 020 7864 7245 to start.
