Front-porch drawings for Teynham and Lynsted homes — checked against the Class D permitted-development limits, drawn to Swale Borough Council's frontage guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Swale Borough Council granted 94% of the householder planning decisions it made in its latest published year — 7 points above the 87% England-wide householder average. Teynham and Lynsted contains Cellar Hill and Greenstreet, Teynham, Kingsdown, Lewson Street conservation areas (Cellar Hill and Greenstreet, Teynham designated 1970), 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.
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. Teynham and Lynsted carries at least one Article 4 direction, and conservation areas including Cellar Hill and Greenstreet, Teynham, Kingsdown and Lewson Street remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Teynham and Lynsted is determined against an 8-week statutory target.
Cellar Hill and Greenstreet, Teynham (conservation area designated in 1970), Kingsdown (conservation area designated in 1976), Lewson Street (conservation area designated in 1975), Lynsted - Bogle (conservation area designated in 1970), Lynsted - The Street (conservation area designated in 1970), Tonge (conservation area designated in 1987), Luddenham (civil parish within Teynham and Lynsted), Lynsted with Kingsdown (civil parish within Teynham and Lynsted), Norton, Buckland and Stone (civil parish within Teynham and Lynsted), Oare (civil parish within Teynham and Lynsted), Teynham (civil parish within Teynham and Lynsted) and Tonge (civil parish within Teynham and Lynsted) — these are the Teynham and Lynsted pockets our drawings cover most. Heritage designations here include Cellar Hill and Greenstreet, Teynham, Kingsdown, Lewson Street, Lynsted - Bogle, Lynsted - The Street and Tonge. Swale Borough Council weighs each proposal against Swale Borough Council's adopted local plan and its householder design guidance, where the 2,940 homes here are 28% pre-1900, 12% 1955-1964, 10% 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 gabled roofs typical of that period's building, over Victorian and earlier houses (28% of 2,940 homes), late-1950s and early-1960s houses (12%) and late-1960s and early-1970s houses (10%).
Teynham and Lynsted's designated heritage is specific, and it is the first thing we check against your address: Cellar Hill and Greenstreet, Teynham (conservation area designated in 1970), Kingsdown (conservation area designated in 1976), Lewson Street (conservation area designated in 1975), Lynsted - Bogle (conservation area designated in 1970), Lynsted - The Street (conservation area designated in 1970) and Tonge (conservation area designated in 1987). Inside those boundaries permitted development is curtailed and Swale 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.
Beyond the designated areas, Teynham and Lynsted takes in Luddenham, Lynsted with Kingsdown, Norton, Buckland and Stone, Oare, Teynham and Tonge. Swale Borough Council has 22 recorded Article 4 directions, removing permitted development for rear and side extensions — check the address before assuming PD applies in Teynham and Lynsted.
On stock, Teynham and Lynsted is Victorian and earlier houses (28% of 2,940 homes), late-1950s and early-1960s houses (12%) and late-1960s and early-1970s houses (10%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow gabled roofs typical of that period's building govern what a loft or rear projection can realistically be. Swale Borough Council decided 329 householder applications in the latest published year and granted 94%, with 37% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for Teynham and Lynsted runs pre-1900 28% (810 homes), 1900-1918 0% (10 homes), 1919-1929 1% (20 homes), 1930-1939 5% (150 homes), 1945-1954 6% (190 homes), 1955-1964 12% (360 homes), 1965-1972 10% (300 homes), 1973-1982 3% (100 homes), 1983-1992 4% (110 homes), 1993-1999 4% (110 homes) and 2000-2008 4% (110 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.
Swale Borough Council also decides for Abbey, Borden and Grove Park, Boughton and Courtenay, East Downs, Sheerness, Watling and West Downs, so a decision in Teynham and Lynsted 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 and 2 Flint Cottages, 20 East Street, 43-47, 49-51, 54, 56, 57, 59-72 Marine Parade and 49, 88, 90, 104, 114-128(evens), 132-140(evens) The Street and 1 & 2 Chapel Cottages. 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.

A porch is the smallest thing most people build and the most visible. It sits on the principal elevation, so Swale Borough Council reads it against the rhythm of the whole street rather than against your own house alone. Teynham and Lynsted is largely Victorian and earlier houses (28% of 2,940 homes), late-1950s and early-1960s houses (12%) and late-1960s and early-1970s houses (10%), 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 Teynham and Lynsted 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 Teynham and Lynsted's conservation areas — Cellar Hill and Greenstreet, Teynham, Kingsdown, Lewson Street, Lynsted - Bogle, Lynsted - The Street and Tonge among them — a porch is assessed on materials, roof form and how the door surround is treated. Swale Borough Council has 22 recorded Article 4 directions, removing permitted development for rear and side extensions — check the address before assuming PD applies in Teynham and Lynsted.
Most modest porches are permitted development. You will need to apply to Swale Borough Council if any of these apply:
We draw the porch to scale against the three Class D thresholds, show the highway boundary on the block plan, and detail the roof, door surround and threshold so Swale Borough Council — and your neighbours — can see exactly what will be built.
Below is Swale Borough Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Swale Borough Council granted 94% of its householder applications in the year to 31 March 2026, and Cellar Hill and Greenstreet, Teynham 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.

Across Cellar Hill and Greenstreet, Teynham, Kingsdown and Lewson Street, 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 victorian and earlier houses (28% of 2,940 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.
Teynham and Lynsted contains Cellar Hill and Greenstreet, Teynham, Kingsdown, Lewson Street conservation areas (Cellar Hill and Greenstreet, Teynham designated 1970), 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.
We draw porches on every street type in Teynham and Lynsted. A few of the areas where porch work comes up most often:

Class D sets three thresholds. This is how the common cases fall either side of them.
| Porch type | Permitted development? | What decides it | What Swale Borough Council checks |
|---|---|---|---|
| Open canopy over the door | Usually yes — no enclosed floor area | Whether it is enclosed | Projection, materials, roof form |
| Enclosed porch under 3m² | Yes, if under 3m high and 2m from the highway boundary | External floor area | Highway stand-off, frontage design |
| Enclosed porch over 3m² | No — full application | External floor area | Bulk on the principal elevation |
| Porch in a conservation area | Only if it meets Class D and no Article 4 applies | Designation status | Materials, door detail, streetscape |
| Porch on a listed building | No — listed building consent required | Listing | Impact on special interest |
Thresholds from the Town and Country Planning (General Permitted Development) (England) Order 2015, Schedule 2, Part 1, Class D.
A fixed process built around how Swale Borough Council validates and decides frontage work — most porch drawings are submission-ready within seven days of survey.
Send us your Teynham and Lynsted 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 Swale Borough Council decisions.
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.
Chartered designers develop the porch to your brief, either inside the Class D limits or as a full application drawn to Swale Borough Council's design guidance, with materials and roof form matched to the house.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Swale Borough Council issues its decision.
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 Swale Borough Council. On designated land, and on listed buildings, the position is different and we check it before drawing. This applies to your Teynham and Lynsted address specifically.
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 Teynham and Lynsted address specifically. Swale Borough Council is the decision-maker.
No part of a permitted-development porch may be within 2 metres of any boundary of the property that fronts a highway. In Teynham and Lynsted 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. Swale Borough Council is the decision-maker.
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 Swale Borough 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 Cellar Hill and Greenstreet, Teynham and Kingsdown we confirm the position on your specific address first. This applies to your Teynham and Lynsted address specifically.
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 Teynham and Lynsted address specifically. Swale Borough Council is the decision-maker.
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 Teynham and Lynsted address specifically. Swale Borough Council is the decision-maker.
We quote each Teynham and Lynsted 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 Swale Borough Council approves. Call 020 7864 7245 to start.
