East Preston planning decisions and design rules

Arun District Council granted 94% of the householder planning decisions it made in its latest published year — 7 points above the 87% England-wide householder average. East Preston contains the East Preston Station Road conservation area (East Preston Station Road designated 1994), 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) 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. In conservation areas such as East Preston Station Road those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in East Preston is determined against an 8-week statutory target.

East Preston Station Road (conservation area designated in 1994), Rustington (civil parish within East Preston), Angmering (civil parish within East Preston) and Kingston (civil parish within East Preston) — these are the East Preston pockets our drawings cover most. Heritage designations here include East Preston Station Road. Arun District Council weighs each proposal against the adopted Arun local plan and Arun District Council's design guidance for householder work, where the 3,680 homes here are 33% 1955-1964, 19% 1930-1939, 12% 1965-1972, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow gabled roofs typical of that period's building and hipped roofs with shallow pitches typical of 1930s building, over late-1950s and early-1960s houses (33% of 3,680 homes), 1930s semi-detached and detached houses (19%) and late-1960s and early-1970s houses (12%).

Why a East Preston scheme is judged on East Preston terms

What is permitted in East Preston turns on designation first, so that is where we start: East Preston Station Road (conservation area designated in 1994). Inside those boundaries permitted development is curtailed and Arun 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, East Preston takes in Rustington, Angmering and Kingston. No Article 4 direction is recorded for Arun District Council, but East Preston's 1 conservation area still limit permitted development on those streets.

On stock, East Preston is late-1950s and early-1960s houses (33% of 3,680 homes), 1930s semi-detached and detached houses (19%) and late-1960s and early-1970s houses (12%) — which is why shallow gabled roofs typical of that period's building and hipped roofs with shallow pitches typical of 1930s building govern what a loft or rear projection can realistically be. Arun District Council decided 453 householder applications in the latest published year and granted 94%, with 99% issued inside the eight-week target. We draw to that record rather than to a national average.

The full build-period split for East Preston runs pre-1900 2% (80 homes), 1900-1918 2% (90 homes), 1919-1929 1% (20 homes), 1930-1939 19% (690 homes), 1945-1954 2% (80 homes), 1955-1964 33% (1,200 homes), 1965-1972 12% (450 homes), 1973-1982 10% (380 homes), 1983-1992 6% (220 homes), 1993-1999 4% (140 homes) and 2000-2008 3% (100 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.

Arun District Council also decides for Angmering & Findon, Arundel & Walberton, Barnham, Beach, Bersted, Hotham, Marine and Orchard, so a decision in East Preston 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.

Why a porch is judged on the East Preston street, not the plan

A porch is the smallest thing most people build and the most visible. It sits on the principal elevation, so Arun District Council reads it against the rhythm of the whole street rather than against your own house alone. East Preston is largely late-1950s and early-1960s houses (33% of 3,680 homes), 1930s semi-detached and detached houses (19%) and late-1960s and early-1970s houses (12%), and where a run of houses shares one front-door detail, a porch that ignores it stands out from fifty metres away.

The three Class D numbers do most of the work: 3 square metres of external floor area, 3 metres of height, and a 2-metre stand-off from any boundary that fronts a highway. That last one catches more porches in East Preston than the other two put together, because front gardens are shallow and the boundary is measured to the highway line, not to the kerb. We measure it on site and set the porch inside the limit, or we tell you honestly that it needs an application.

In East Preston's conservation areas — East Preston Station Road among them — a porch is assessed on materials, roof form and how the door surround is treated. No Article 4 direction is recorded for Arun District Council, but East Preston's 1 conservation area still limit permitted development on those streets.

Does a porch need planning permission in East Preston?

Most modest porches are permitted development. You will need to apply to Arun District Council if any of these apply:

  • The external floor area measures more than 3 square metres
  • Any part of the porch stands higher than 3 metres above ground level
  • Any part sits within 2 metres of a boundary that fronts a highway
  • The house is in a conservation area such as East Preston Station Road, where frontage changes are controlled
  • The building is listed — listed building consent is required whatever the size
  • The porch encloses a shared entrance to flats rather than a single house

East Preston porch decisions — live from council data

Below is Arun District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Arun District Council granted 94% of its householder applications in the year to 31 March 2026, and East Preston Station Road shapes what is approved here. A porch application turns on frontage design and the highway stand-off, so a pack that dimensions both is decided faster than a sketch.

What porches get approved across East Preston

Across East Preston Station Road, Rustington and Angmering, the porches that go through are the ones that borrow from the house: the same brick or render, a roof pitched to match, and a door and side-light proportioned to the original opening. On late-1950s and early-1960s houses (33% of 3,680 homes), an open-sided canopy is often the better answer than an enclosed porch — it stays clear of the floor-area limit and leaves the frontage legible.

East Preston contains the East Preston Station Road conservation area (East Preston Station Road designated 1994), so materials, fenestration and roof form are assessed against the appraisal, which is exactly the sort of local reading a porch has to satisfy. Where the 2-metre highway stand-off cannot be met, we either recess the porch behind the building line or prepare a full householder application with an elevation that shows the porch in the context of its neighbours — the drawing that answers the officer's real question.

Is your East Preston porch permitted development or a full application?

Class D sets three thresholds. This is how the common cases fall either side of them.

Four steps to an approved East Preston porch

A fixed process built around how Arun District Council validates and decides frontage work — most porch drawings are submission-ready within seven days of survey.

  1. 1

    Free approval check

    Send us your East Preston postcode. We confirm conservation, Article 4 and listing status, measure the front boundary against the 2-metre highway rule, and score your odds against live Arun District Council decisions.

  2. 2

    Measured survey

    We measure the frontage, threshold level, door opening and the distance to the highway boundary — the four numbers a porch application stands or falls on.

  3. 3

    Porch design & drawings

    Chartered designers develop the porch to your brief, either inside the Class D limits or as a full application drawn to Arun District Council's design guidance, with materials and roof form matched to the house.

  4. 4

    Submission & follow-through

    We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Arun District Council issues its decision.

Frequently asked questions

Do I need planning permission for a porch in East Preston?

Usually not, provided it meets all three Class D limits: no more than 3 square metres of external floor area, no more than 3 metres high, and no part within 2 metres of a boundary fronting a highway. Break any one and you need a householder application to Arun District Council. On designated land, and on listed buildings, the position is different and we check it before drawing. This applies to your East Preston address specifically.

How is the 3 square metres measured on a East Preston porch?

It is the external floor area — measured to the outside face of the porch walls, not the usable space inside. That catches people out, because a porch that feels small internally can exceed 3 square metres once the wall thickness is counted. We measure and dimension it on the plan so the figure is beyond argument at validation. This applies to your East Preston address specifically. Arun District Council is the decision-maker.

What is the 2 metre highway rule for porches in East Preston?

No part of a permitted-development porch may be within 2 metres of any boundary of the property that fronts a highway. In East Preston this is the limit that most often pushes a porch into a full application, because front gardens are shallow. The measurement is to the boundary line, which is not always where the kerb or the fence sits — we establish it on survey. Arun District Council is the decision-maker.

Can I build a porch in a East Preston conservation area?

Yes, but the design bar is higher. Class D is not automatically removed in a conservation area, so a compliant porch can still be permitted development — however Arun District Council will expect materials, roof pitch and door detail to respect the area's character, and an Article 4 direction can remove the right entirely. In East Preston Station Road we confirm the position on your specific address first.

Does a porch need building regulations approval in East Preston?

A porch is exempt from most building regulations if it is under 30 square metres, at ground level, separated from the house by the existing external door, and any glazing and electrics meet Parts K, N and P. Remove the original front door and the porch becomes part of the heated envelope, at which point insulation and Part L apply. We flag which side of that line your design falls on. This applies to your East Preston address specifically. Arun District Council is the decision-maker.

How long does Arun District Council take to decide a porch application?

A householder application runs to an eight-week statutory target, and a lawful development certificate to the same. The realistic risk is not the decision but validation — an incomplete pack is returned rather than determined. We prepare the submission validation-complete and handle officer queries so the timetable holds. This applies to your East Preston address specifically. Arun District Council is the decision-maker.

How much do porch plans in East Preston cost?

We quote each East Preston porch individually, because frontage type and boundary position vary house to house, and send a fixed, no-obligation quote within one working day. It covers the full drawing pack with free revisions until Arun District Council approves. Call 020 7864 7245 to start.
