Dormer loft conversion plans in Boughton and Courtenay

Boughton and Courtenay planning decisions and design rules

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. Boughton and Courtenay contains Boughton - Boughton Church, Boughton - Boughton Street, Boughton - South Street conservation areas (Boughton - Boughton Church designated 1976), 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.

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. Boughton and Courtenay carries at least one Article 4 direction, and conservation areas including Boughton - Boughton Church, Boughton - Boughton Street and Boughton - South Street remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Boughton and Courtenay is determined against an 8-week statutory target.

Boughton - Boughton Church (conservation area designated in 1976), Boughton - Boughton Street (conservation area designated in 1970), Boughton - South Street (conservation area designated in 1975), Goodnestone (conservation area designated in 1999), Graveney - Graveney Bridge (conservation area designated in 1970), Graveney - Graveney Church (conservation area designated in 1999), Hernhill (conservation area designated in 1971), Hernhill - Dargate (conservation area designated in 1999), Hernhill - Fostall (conservation area designated in 1999), Selling (conservation area designated in 1973), Selling - Shepherd's Hill (conservation area designated in 2000), Sheldwich (conservation area designated in 1982), Staplestreet (conservation area designated in 1971), Boughton under Blean (civil parish within Boughton and Courtenay), Dunkirk (civil parish within Boughton and Courtenay), Graveney with Goodnestone (civil parish within Boughton and Courtenay), Hernhill (civil parish within Boughton and Courtenay), Selling (civil parish within Boughton and Courtenay) and Sheldwich (civil parish within Boughton and Courtenay) — these are the Boughton and Courtenay pockets our drawings cover most. Heritage designations here include Boughton - Boughton Church, Boughton - Boughton Street, Boughton - South Street, Goodnestone, Graveney - Graveney Bridge, Graveney - Graveney Church, Hernhill, Hernhill - Dargate, Hernhill - Fostall, Selling, Selling - Shepherd's Hill, Sheldwich and Staplestreet. Swale Borough Council weighs each proposal against the adopted Swale local plan and Swale Borough Council's design guidance for householder work, where the 2,590 homes here are 36% pre-1900, 9% 1955-1964, 9% 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 (36% of 2,590 homes), late-1950s and early-1960s houses (9%) and late-1960s and early-1970s houses (9%).

Why a Boughton and Courtenay scheme is judged on Boughton and Courtenay terms

What is permitted in Boughton and Courtenay turns on designation first, so that is where we start: Boughton - Boughton Church (conservation area designated in 1976), Boughton - Boughton Street (conservation area designated in 1970), Boughton - South Street (conservation area designated in 1975), Goodnestone (conservation area designated in 1999), Graveney - Graveney Bridge (conservation area designated in 1970), Graveney - Graveney Church (conservation area designated in 1999), Hernhill (conservation area designated in 1971), Hernhill - Dargate (conservation area designated in 1999), Hernhill - Fostall (conservation area designated in 1999), Selling (conservation area designated in 1973), Selling - Shepherd's Hill (conservation area designated in 2000), Sheldwich (conservation area designated in 1982) and Staplestreet (conservation area designated in 1971). 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, Boughton and Courtenay takes in Boughton under Blean, Dunkirk, Graveney with Goodnestone, Hernhill, Selling and Sheldwich. 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 Boughton and Courtenay.

On stock, Boughton and Courtenay is Victorian and earlier houses (36% of 2,590 homes), late-1950s and early-1960s houses (9%) and late-1960s and early-1970s houses (9%) — 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. We draw to that record rather than to a national average.

The full build-period split for Boughton and Courtenay runs pre-1900 36% (920 homes), 1900-1918 3% (70 homes), 1919-1929 1% (30 homes), 1930-1939 4% (110 homes), 1945-1954 7% (190 homes), 1955-1964 9% (240 homes), 1965-1972 9% (230 homes), 1973-1982 7% (190 homes), 1983-1992 7% (170 homes), 1993-1999 5% (120 homes) and 2000-2008 3% (70 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, East Downs, Sheerness, Teynham and Lynsted, Watling and West Downs, so a decision in Boughton and Courtenay 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.

The rear dormer, drawn for Boughton and Courtenay roofs

The box dormer is the workhorse loft, and most of Boughton and Courtenay is built for it — the borough runs to Victorian and earlier houses (36% of 2,590 homes), late-1950s and early-1960s houses (9%) and late-1960s and early-1970s houses (9%) under steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow gabled roofs typical of that period's building, and a flat-roofed box across the rear slope is the cheapest cubic metre of full-height space those roofs give up. Swale Borough Council tests the dormer against the adopted Swale local plan and Swale Borough Council's design guidance for householder work, and because permitted development turns on a number, the volume you propose against the volume you have left is the first thing an officer or a certificate checks.

That is why the arithmetic goes on the drawings. We calculate the box against the 40- or 50-cubic-metre allowance, count any earlier roof enlargement into the total, hold the flat roof below the ridge and set the face back off the eaves so the dormer reads as subordinate. Boughton and Courtenay contains Boughton - Boughton Church, Boughton - Boughton Street, Boughton - South Street conservation areas (Boughton - Boughton Church designated 1976), so materials, fenestration and roof form are assessed against the appraisal, so the cheeks, the window line and the material are drawn to answer it rather than invite a query.

Where Boughton and Courtenay's streets are protected — Boughton - Boughton Church, Boughton - Boughton Street, Boughton - South Street, Goodnestone, Graveney - Graveney Bridge, Graveney - Graveney Church, Hernhill, Hernhill - Dargate, Hernhill - Fostall, Selling, Selling - Shepherd's Hill, Sheldwich and Staplestreet among them — the Class B dormer right is switched off and even a modest rear box needs consent. 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 Boughton and Courtenay. We confirm the designation before the box is sized.
