The full drawing set for a St Leonard's application — location and block plans, existing and proposed floor plans, elevations and sections, drawn to Exeter 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.
Exeter City Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. The historic core and Cathedral setting are tightly protected, and heritage impact is weighed on schemes visible from Southernhay and the walled city, 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.
Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. In conservation areas such as St Leonard's, Mount Radford and Southernhay & The Friars those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in St Leonard's is determined against an 8-week statutory target.
Southernhay (elegant Georgian brick terraces facing the tree-lined lawns), Mount Radford (Regency and early-Victorian villas around St Leonard's Road), Baring Crescent (a listed early-Victorian crescent off Magdalen Road), Wonford Road (large detached Victorian villas on generous plots) and Barnfield (Georgian and Victorian terraces near Southernhay and the theatre) — these are the St Leonard's pockets our drawings cover most. Heritage designations here include St Leonard's, Mount Radford and Southernhay & The Friars. Exeter City Council weighs each proposal against the Exeter Local Plan / Core Strategy and the emerging Exeter Plan, where conservation-area frontages here are held to detailed standards on materials, render, windows and boundary walls. Many of the larger St Leonard's villas are subdivided into flats and maisonettes, which carry no householder permitted-development rights.. On roofs the borough is parapet-concealed slate roofs on the Georgian terraces and hipped and gabled Welsh-slate roofs on the Victorian villas, over Georgian and Regency terraces around Southernhay and Barnfield, substantial Victorian villas in local red breccia and brick and period houses subdivided into flats.
Whatever you are building, Exeter 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. Exeter City Council assesses each proposal against the Exeter Local Plan / Core Strategy and the emerging Exeter Plan, 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 St Leonard's's stock, which runs to Georgian and Regency terraces around Southernhay and Barnfield, substantial Victorian villas in local red breccia and brick and period houses subdivided into flats, the same scheme is drawn differently to answer the concerns officers raise here. The historic core and Cathedral setting are tightly protected, and heritage impact is weighed on schemes visible from Southernhay and the walled city, so the pack is built to pre-empt exactly that.
Where the property sits in a conservation area — St Leonard's, Mount Radford and Southernhay & The Friars among St Leonard's's — validation is stricter still, often demanding heritage detail and sometimes additional plans. St Leonard's sits outside the city's HMO Article 4 Direction, which is drawn around the student belt north of the centre, but the St Leonard's, Mount Radford and Southernhay & The Friars conservation areas remove or restrict permitted-development rights across most of its Georgian and Victorian streets. We confirm the designation before drawing so the pack meets the higher bar first time.

Exeter 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 Exeter 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 Exeter City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Exeter grants around 87% of the applications it decides, with conservation-area design control across St Leonard's and Southernhay the recurring constraint on roof, rear and frontage changes. 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 — Exeter 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 St Leonard's applications lose weeks. We draw to the checklist so this never happens.
Second is the planning judgement itself, once the pack is valid. Conservation-area frontages here are held to detailed standards on materials, render, windows and boundary walls. Across Southernhay, Mount Radford and Baring Crescent 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 St Leonard's neighbourhoods and property types we prepare drawings for most often:
Planning drawings for Southernhay's elegant Georgian brick terraces facing the tree-lined lawns — scaled, validation-ready and drawn to Exeter City Council's guidance.
Planning drawings for Mount Radford's Regency and early-Victorian villas around St Leonard's Road — scaled, validation-ready and drawn to Exeter City Council's guidance.
Planning drawings for Baring Crescent's a listed early-Victorian crescent off Magdalen Road — scaled, validation-ready and drawn to Exeter City Council's guidance.
Planning drawings for Wonford Road's large detached Victorian villas on generous plots — scaled, validation-ready and drawn to Exeter City Council's guidance.
Planning drawings for Barnfield's Georgian and Victorian terraces near Southernhay and the theatre — scaled, validation-ready and drawn to Exeter City Council's guidance.
The route decides what Exeter City Council needs and how long it takes. This is how the common St Leonard's 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 St Leonard's and Mount Radford, householder permitted-development rights are often restricted, so a full application and heritage detail may be required.
A fixed process built around how Exeter City Council validates and decides — most drawing sets are submission-ready within seven days of survey.
Send us your St Leonard's 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 Exeter City 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 Exeter City Council's checklist.
We lodge the application on the Planning Portal, manage validation and case-officer queries, and revise the drawings free until Exeter City Council issues its decision.
Exeter 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. This applies to your St Leonard's address specifically.
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. Exeter 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. This applies to your St Leonard's address specifically.
Yes. We prepare the full drawing set, lodge it on the Planning Portal on your behalf, pay the Exeter 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. This applies to your St Leonard's address specifically.
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 Exeter City Council's checklist the application validates quickly, so the statutory period begins without the delay a returned pack causes. This applies to your St Leonard's address specifically.
You do not strictly need a planning application, but scaled existing and proposed drawings are still worth having: a lawful development certificate from Exeter 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 St Leonard's and Mount Radford, permitted-development rights are often removed, so a full application may be needed after all — we confirm which before you commit.
We price each St Leonard's 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 Exeter City Council decides. The Exeter City Council application fee is separate and paid to the council. Call 020 7864 7245 to start.
