Planning application drawings in Tonbridge and Malling

Tonbridge and Malling planning decisions and design rules

Tonbridge and Malling Borough Council granted 97% of the householder planning decisions it made in its latest published year — 10 points above the 87% England-wide householder average. Tonbridge and Malling contains Addington, Budd's Green, Shipbourne, Butts Hill, Wrotham conservation areas (Addington designated 1971), 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. In conservation areas such as Addington, Budd's Green, Shipbourne and Butts Hill, Wrotham those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Tonbridge and Malling is determined against an 8-week statutory target.

Addington (conservation area designated in 1971), Budd's Green, Shipbourne (conservation area designated in 1993), Butts Hill, Wrotham (conservation area designated in 1993), Claygate Cross, Plaxtol (conservation area designated in 1993), Coldharbour, Hildenborough (conservation area designated in 1993), Fairlawne (conservation area designated in 1972), Fairseat (conservation area designated in 1972), Hadlow (conservation area designated in 1972), Borough Green & Platt (ward of Tonbridge and Malling), Bourne (ward of Tonbridge and Malling), Hildenborough (ward of Tonbridge and Malling), Judd (ward of Tonbridge and Malling), Larkfield (ward of Tonbridge and Malling) and Pilgrims with Ightham (ward of Tonbridge and Malling) — these are the Tonbridge and Malling pockets our drawings cover most. Heritage designations here include Addington, Budd's Green, Shipbourne, Butts Hill, Wrotham, Claygate Cross, Plaxtol, Coldharbour, Hildenborough, Fairlawne, Fairseat and Hadlow. Tonbridge and Malling Borough Council weighs each proposal against Tonbridge and Malling Borough Council's adopted local plan and its householder design guidance, where the 16,010 homes here are 18% pre-1900, 14% 1955-1964, 6% 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 (18% of 16,010 homes), late-1950s and early-1960s houses (14%) and late-1960s and early-1970s houses (6%).

Why a Tonbridge and Malling scheme is judged on Tonbridge and Malling terms

What is permitted in Tonbridge and Malling turns on designation first, so that is where we start: Addington (conservation area designated in 1971), Budd's Green, Shipbourne (conservation area designated in 1993), Butts Hill, Wrotham (conservation area designated in 1993), Claygate Cross, Plaxtol (conservation area designated in 1993), Coldharbour, Hildenborough (conservation area designated in 1993), Fairlawne (conservation area designated in 1972), Fairseat (conservation area designated in 1972) and Hadlow (conservation area designated in 1972). Inside those boundaries permitted development is curtailed and Tonbridge and Malling 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, Tonbridge and Malling takes in Borough Green & Platt, Bourne, Hildenborough, Judd, Larkfield and Pilgrims with Ightham. No Article 4 direction is recorded for Tonbridge and Malling Borough Council, but the district's 8 conservation areas still limit permitted development on those streets.

On stock, Tonbridge and Malling is Victorian and earlier houses (18% of 16,010 homes), late-1950s and early-1960s houses (14%) and late-1960s and early-1970s houses (6%) — 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. Tonbridge and Malling Borough Council decided 515 householder applications in the latest published year and granted 97%, with 49% issued inside the eight-week target. We draw to that record rather than to a national average.

The full build-period split for Tonbridge and Malling runs pre-1900 3% (190 homes), 1900-1918 0% (30 homes), 1919-1929 0% (10 homes), 1930-1939 6% (350 homes), 1945-1954 3% (170 homes), 1955-1964 30% (1,850 homes), 1965-1972 33% (1,990 homes), 1973-1982 4% (260 homes), 1983-1992 5% (310 homes), 1993-1999 4% (220 homes) and 2000-2008 3% (170 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.

Tonbridge and Malling Borough Council also decides for Borough Green & Platt, Bourne, Hildenborough, Judd, Larkfield and Pilgrims with Ightham, so a decision in Tonbridge and Malling 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.

What goes in a Tonbridge and Malling planning application

Whatever you are building, Tonbridge and Malling Borough 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. Tonbridge and Malling Borough Council assesses each proposal against Tonbridge and Malling Borough Council's adopted local plan and its householder design guidance, 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 Tonbridge and Malling's stock, which runs to Victorian and earlier houses (18% of 16,010 homes), late-1950s and early-1960s houses (14%) and late-1960s and early-1970s houses (6%), the same scheme is drawn differently to answer the concerns officers raise here. Tonbridge and Malling contains Addington, Budd's Green, Shipbourne, Butts Hill, Wrotham conservation areas (Addington designated 1971), 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 — Addington, Budd's Green, Shipbourne, Butts Hill, Wrotham, Claygate Cross, Plaxtol, Coldharbour, Hildenborough, Fairlawne, Fairseat and Hadlow among Tonbridge and Malling's — validation is stricter still, often demanding heritage detail and sometimes additional plans. No Article 4 direction is recorded for Tonbridge and Malling Borough Council, but the district's 8 conservation areas still limit permitted development on those streets. We confirm the designation before drawing so the pack meets the higher bar first time.
