The full drawing set for a Horndean Catherington application — location and block plans, existing and proposed floor plans, elevations and sections, drawn to East Hampshire District 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.
East Hampshire District Council granted 91% of the householder planning decisions it made in its latest published year — 4 points above the 87% England-wide householder average. Horndean Catherington contains the Catherington conservation area (Catherington designated 2003), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant interwar (1918–1939) 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. Horndean Catherington carries at least one Article 4 direction, and conservation areas including Catherington remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Horndean Catherington is determined against an 8-week statutory target.
Catherington (conservation area designated in 2003) and Horndean (civil parish within Horndean Catherington) — these are the Horndean Catherington pockets our drawings cover most. Heritage designations here include Catherington. East Hampshire District Council weighs each proposal against the adopted East Hampshire local plan and East Hampshire District Council's design guidance for householder work, where the 1,100 homes here are 28% 1983-1992, 13% 1973-1982, 11% 1930-1939, which is what sets the realistic roof and rear-projection options. On roofs the borough is trussed-rafter roofs typical of 1980s building and shallow trussed roofs typical of 1970s building, over 1980s estate houses (28% of 1,100 homes), 1970s and early-1980s houses (13%) and 1930s semi-detached and detached houses (11%).
Horndean Catherington's designated heritage is specific, and it is the first thing we check against your address: Catherington (conservation area designated in 2003). Inside those boundaries permitted development is curtailed and East Hampshire District 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, Horndean Catherington takes in Horndean. East Hampshire District Council has 50 recorded Article 4 directions — check the address before assuming PD applies in Horndean Catherington.
On stock, Horndean Catherington is 1980s estate houses (28% of 1,100 homes), 1970s and early-1980s houses (13%) and 1930s semi-detached and detached houses (11%) — which is why trussed-rafter roofs typical of 1980s building and shallow trussed roofs typical of 1970s building govern what a loft or rear projection can realistically be. East Hampshire District Council decided 327 householder applications in the latest published year and granted 91%, with 24% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for Horndean Catherington runs pre-1900 6% (70 homes), 1900-1918 1% (10 homes), 1919-1929 3% (30 homes), 1930-1939 11% (120 homes), 1945-1954 2% (20 homes), 1955-1964 6% (70 homes), 1965-1972 5% (60 homes), 1973-1982 13% (140 homes), 1983-1992 28% (310 homes), 1993-1999 9% (100 homes) and 2000-2008 3% (30 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.
East Hampshire District Council also decides for Alton Holybourne, Alton Whitedown, Bentworth & Froyle, Bramshott & Liphook, Buriton & East Meon, Four Marks & Medstead, Headley and Liss, so a decision in Horndean Catherington 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 Ajax House/Plowden House, Liphook, Bedford Road, Petersfield, Bellhanger Enterprises, Bentworth and Bentley Business Park, Bentley. 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.

Dwelling stock from VOA council-tax data at 31 March 2025; conservation-area and Article 4 counts from planning.data.gov.uk (MHCLG); decision figures are East Hampshire District Council's own, from MHCLG live table PS2 for the year to 31 March 2026.
Whatever you are building, East Hampshire District 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. East Hampshire District Council assesses each proposal against the adopted East Hampshire local plan and East Hampshire District Council's design guidance for householder work, 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 Horndean Catherington's stock, which runs to 1980s estate houses (28% of 1,100 homes), 1970s and early-1980s houses (13%) and 1930s semi-detached and detached houses (11%), the same scheme is drawn differently to answer the concerns officers raise here. Horndean Catherington contains the Catherington conservation area (Catherington designated 2003), 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 — Catherington among Horndean Catherington's — validation is stricter still, often demanding heritage detail and sometimes additional plans. East Hampshire District Council has 50 recorded Article 4 directions — check the address before assuming PD applies in Horndean Catherington. We confirm the designation before drawing so the pack meets the higher bar first time.

East Hampshire District 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 East Hampshire District 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 East Hampshire District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. East Hampshire District Council granted 91% of its householder applications in the year to 31 March 2026, and Catherington shapes what is approved here. 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 — East Hampshire District 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 Horndean Catherington applications lose weeks. We draw to the checklist so this never happens.
Second is the planning judgement itself, once the pack is valid. The 1,100 homes here are 28% 1983-1992, 13% 1973-1982, 11% 1930-1939, which is what sets the realistic roof and rear-projection options. Across Catherington and Horndean 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 Horndean Catherington neighbourhoods and property types we prepare drawings for most often:
Planning drawings for Catherington's conservation area designated in 2003 — scaled, validation-ready and drawn to East Hampshire District Council's guidance.
Planning drawings for Horndean's civil parish within Horndean Catherington — scaled, validation-ready and drawn to East Hampshire District Council's guidance.
The route decides what East Hampshire District Council needs and how long it takes. This is how the common Horndean Catherington 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 Catherington, householder permitted-development rights are often restricted, so a full application and heritage detail may be required.
A fixed process built around how East Hampshire District Council validates and decides — most drawing sets are submission-ready within seven days of survey.

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 East Hampshire District Council's checklist.
We lodge the application on the Planning Portal, manage validation and case-officer queries, and revise the drawings free until East Hampshire District Council issues its decision.
East Hampshire District 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 Horndean Catherington 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. East Hampshire District 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 Horndean Catherington address specifically.
Yes. We prepare the full drawing set, lodge it on the Planning Portal on your behalf, pay the East Hampshire District 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 Horndean Catherington 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 East Hampshire District Council's checklist the application validates quickly, so the statutory period begins without the delay a returned pack causes. This applies to your Horndean Catherington 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 East Hampshire District 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 Catherington, permitted-development rights are often removed, so a full application may be needed after all — we confirm which before you commit. This applies to your Horndean Catherington address specifically.
We price each Horndean Catherington 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 East Hampshire District Council decides. The East Hampshire District Council application fee is separate and paid to the council.
