What the data says about planning in Havant St Faith's

Havant Borough Council granted 95% of the householder planning decisions it made in its latest published year — 8 points above the 87% England-wide householder average. Havant St Faith's contains Langstone, Lymbourn Road, Mill Lane conservation areas (Langstone designated 2026), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant postwar (1945–1970) housing stock sets the design brief on most streets.

Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Havant Borough Council needs a full application. Havant St Faith's carries at least one Article 4 direction, and conservation areas including Langstone, Lymbourn Road and Mill Lane remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Havant St Faith's is determined against an 8-week statutory target.

Langstone (conservation area designated in 2026), Lymbourn Road (conservation area designated in 2026), Mill Lane (conservation area designated in 2026), St Faith's (conservation area designated in 2026), Wade Court (conservation area designated in 2026) and Warblington (conservation area designated in 2026) — these are the Havant St Faith's pockets our drawings cover most. Heritage designations here include Langstone, Lymbourn Road, Mill Lane, St Faith's, Wade Court and Warblington. Havant Borough Council weighs each proposal against the adopted Havant local plan and Havant Borough Council's design guidance for householder work, where the 5,420 homes here are 17% 1965-1972, 15% 1955-1964, 11% 1973-1982, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow-pitched roofs and integral garages typical of that period's building and shallow gabled roofs typical of that period's building, over late-1960s and early-1970s houses (17% of 5,420 homes), late-1950s and early-1960s houses (15%) and 1970s and early-1980s houses (11%).

Designations, stock and decisions in Havant St Faith's

Heritage designation is the single biggest variable in Havant St Faith's, and it is address-specific: Langstone (conservation area designated in 2026), Lymbourn Road (conservation area designated in 2026), Mill Lane (conservation area designated in 2026), St Faith's (conservation area designated in 2026), Wade Court (conservation area designated in 2026) and Warblington (conservation area designated in 2026). Inside those boundaries permitted development is curtailed and Havant Borough 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.

Havant Borough Council has 6 recorded Article 4 directions — check the address before assuming PD applies in Havant St Faith's.

On stock, Havant St Faith's is late-1960s and early-1970s houses (17% of 5,420 homes), late-1950s and early-1960s houses (15%) and 1970s and early-1980s houses (11%) — which is why shallow-pitched roofs and integral garages typical of that period's building and shallow gabled roofs typical of that period's building govern what a loft or rear projection can realistically be. Havant Borough Council decided 286 householder applications in the latest published year and granted 95%, with 31% issued inside the eight-week target. We work from the council's own published record.

The full build-period split for Havant St Faith's runs pre-1900 10% (540 homes), 1900-1918 4% (190 homes), 1919-1929 3% (180 homes), 1930-1939 3% (140 homes), 1945-1954 4% (220 homes), 1955-1964 15% (790 homes), 1965-1972 17% (900 homes), 1973-1982 11% (590 homes), 1983-1992 5% (280 homes), 1993-1999 9% (480 homes) and 2000-2008 3% (180 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.

Havant Borough Council also decides for Bedhampton and Hayling West, so a decision in Havant St Faith's 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 0164B1, 0164B2, 0164B3 and 2967. 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.

Side returns drawn for Havant St Faith's's period terraces

The side return is the classic terrace fix, and Havant St Faith's has the stock for it — the borough is built largely from late-1960s and early-1970s houses (17% of 5,420 homes), late-1950s and early-1960s houses (15%) and 1970s and early-1980s houses (11%), and the Victorian and Edwardian versions almost all have an L-shaped back addition with a wasted alley beside it. Fill that alley and the dark galley kitchen becomes a bright, square room the full width of the house. Havant Borough Council judges the infill against the adopted Havant local plan and Havant Borough Council's design guidance for householder work, and because it runs along the party boundary, the neighbour relationship is read before the design.

That boundary is where the drawings earn their keep. We set the infill wall on or up to the line, keep the roof — usually a glazed lantern or a shallow pitch tying into the existing back-addition slope — below the neighbour's first-floor windows, and detail the rainwater and party-wall junction so the build is watertight and the Party Wall Act is satisfied. Havant St Faith's contains Langstone, Lymbourn Road, Mill Lane conservation areas (Langstone designated 2026), so materials, fenestration and roof form are assessed against the appraisal, so we resolve it on the section rather than leave it to the case officer.

Many of Havant St Faith's's terraces sit in conservation areas — Langstone, Lymbourn Road, Mill Lane, St Faith's, Wade Court and Warblington among them — where a side extension is no longer permitted development. Havant Borough Council has 6 recorded Article 4 directions — check the address before assuming PD applies in Havant St Faith's. We confirm the designation before a line is drawn.

Does a side return extension need planning permission in Havant St Faith's?

Some single-storey side returns in Havant St Faith's are permitted development, but the width and boundary make an application more likely than for a straight rear extension. You will normally need to apply to Havant Borough Council if any of these apply:

  • The side extension is wider than half the width of the original house
  • It is more than one storey, or higher than 4 metres (or higher than the eaves along the side)
  • The property is on designated land — side extensions are not permitted development in conservation areas
  • You are combining the side return with a rear extension beyond 3 metres, which reads as a wraparound
  • Your terrace is in a conservation area such as Langstone and Lymbourn Road, where side-extension rights are removed
  • An Article 4 direction applies to your street — Havant St Faith's operates several, so this is checked first

Havant St Faith's side return approval rates — live from council data

Below is Havant Borough Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Havant Borough Council granted 95% of its householder applications in the year to 31 March 2026, and Langstone shapes what is approved here. Side returns hinge on width, roof glazing and the party boundary, so a pack that resolves those details upfront is decided faster and refused less often than a DIY submission.

What side return extensions get approved in Havant St Faith's

Across Langstone, Lymbourn Road and Mill Lane, the approved side return is a single-storey infill roofed with a glazed lantern or roof light to pull daylight deep into the plan, its flank wall built on the boundary and finished to match the host brick. On the borough's late-1960s and early-1970s houses (17% of 5,420 homes), this is frequently the single biggest gain in usable ground-floor space, and where it stays within the width and height limits it can proceed under permitted development or a lawful development certificate.

The 5,420 homes here are 17% 1965-1972, 15% 1955-1964, 11% 1973-1982, which is what sets the realistic roof and rear-projection options. We keep the glazed roof below the neighbour's cill line, set the gutter and the party-wall flashing so water and maintenance are designed in, and — where owners want the full open-plan room — pair the infill with a rear extension as a single wraparound application. That way Havant Borough Council sees one coherent scheme rather than two overlapping ones.

Is your Havant St Faith's side return permitted development or a full application?

Whether a side return in Havant St Faith's needs permission comes down to width, storeys and whether the street is designated. This is how the cases compare.

Side return typePermitted development?What it gainsWhat Havant Borough Council checks
Single-storey infill, within limitsOften yes, if under half the house widthFull-width kitchen-dinerWidth, 4m height, roof glazing
Single-storey, over half widthNo — full applicationWider room, more lightBoundary treatment, neighbour amenity

In conservation areas such as Langstone and Lymbourn Road, side extensions are not permitted development and always need a full application.

Four steps to an approved Havant St Faith's side return

A fixed process built around how Havant Borough Council validates and decides side-return applications — most drawings are submission-ready within seven days of survey.

  1. 1

    Free approval check

    Send us your Havant St Faith's postcode and terrace type. We confirm your conservation and Article 4 status, whether the infill stays within the side-extension width limit, and score your odds against live Havant Borough Council decisions.

  2. 2

    Measured survey

    We measure the side alley, the back-addition wall, floor and eaves levels and the neighbour's window heights — the numbers the width limit, roof pitch and party-wall detailing depend on.

  3. 3

    Side return design & drawings

    Chartered designers develop the infill and its glazed roof to your brief, drawn inside the permitted-development limits or to Havant Borough Council's extension guidance, with the boundary and party-wall junction detailed.

  4. 4

    Submission & follow-through

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

Frequently asked questions

Does a side return extension need planning permission in Havant St Faith's?

Sometimes not. A single-storey side-return infill can be permitted development if it is no wider than half the original house, no higher than 4 metres, and the property is not on designated land. In Havant St Faith's you will need a full application to Havant Borough Council for anything wider or taller, for a two-storey side return, and for any side extension in a conservation area such as Langstone and Lymbourn Road, where those rights are removed.

What is a side return extension on a Havant St Faith's terrace?

It is an infill that fills the narrow open alley running alongside the rear back-addition of a Victorian or Edwardian terrace — the strip of ground that is usually too small to use. Building over it squares off the ground floor, so a cramped galley kitchen becomes a full-width room. Havant St Faith's's period terraces are ideally suited to it, which is why the side return is one of the borough's most common extensions. Havant Borough Council is the decision-maker.

Do I need a party wall agreement for a side return in Havant St Faith's?

Almost always. A side return is built on or up to the boundary with your neighbour, so the Party Wall etc. Act applies and you must serve notice before work starts — this is entirely separate from Havant Borough Council's planning decision. We detail the party-wall junction on the drawings and flag the notice early so a surveyor can be appointed without delaying the build. This applies to your Havant St Faith's address specifically.

Can I combine a side return with a rear extension in Havant St Faith's?

Yes, and it is common — the combined L-shape is a wraparound extension. Once the side infill joins a rear projection beyond the permitted-development depth, the whole thing needs a full householder application to Havant Borough Council rather than qualifying as permitted development. We draw it as one coherent scheme so the council assesses a single footprint, which reads more clearly than two overlapping proposals. This applies to your Havant St Faith's address specifically.

How long does Havant Borough Council take to decide a side return application?

A householder planning application in Havant St Faith's runs to a statutory eight-week target, and a lawful development certificate to eight weeks as well, though an incomplete pack can stall at validation. Because a side return involves the boundary and roof glazing, a complete, well-detailed submission matters — we prepare it validation-complete and manage officer queries to keep the decision on track. Havant Borough Council is the decision-maker.

How much do side return extension plans in Havant St Faith's cost?

We price each Havant St Faith's side return individually, because alley width and roof form 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 Havant Borough Council approves, and we confirm at the outset whether your infill is permitted development or needs an application.
