Planning application drawings in Codicote & Kimpton

Householder planning in Codicote & Kimpton — the record

North Hertfordshire District Council granted 95% of the householder planning decisions it made in its latest published year — 8 points above the 87% England-wide householder average. Codicote & Kimpton contains Codicote, Kimpton, Kimpton Bottom conservation areas (Codicote designated 1979), 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.

The permitted-development ceilings are fixed: 40m³ of new roof volume for a terraced loft and 50m³ for a semi or detached house under Class B, plus a 3m single-storey rear extension on a terrace or 4m on a detached house under Class A. In conservation areas such as Codicote, Kimpton and Kimpton Bottom those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Codicote & Kimpton is determined against an 8-week statutory target.

Codicote (conservation area designated in 1979), Kimpton (conservation area designated in 1990), Kimpton Bottom (conservation area designated in 1970), Codicote (civil parish within Codicote & Kimpton) and Kimpton (civil parish within Codicote & Kimpton) — these are the Codicote & Kimpton pockets our drawings cover most. Heritage designations here include Codicote, Kimpton and Kimpton Bottom. North Hertfordshire District Council weighs each proposal against North Hertfordshire District Council's adopted local plan and its householder design guidance, where the 2,330 homes here are 21% 1965-1972, 16% pre-1900, 10% 1983-1992, 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 steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, over late-1960s and early-1970s houses (21% of 2,330 homes), Victorian and earlier houses (16%) and 1980s estate houses (10%).

Codicote & Kimpton: the local constraints that decide your scheme

Before anything is drawn we check your address against the designations that apply in Codicote & Kimpton: Codicote (conservation area designated in 1979), Kimpton (conservation area designated in 1990) and Kimpton Bottom (conservation area designated in 1970). Inside those boundaries permitted development is curtailed and North Hertfordshire 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, Codicote & Kimpton takes in Codicote and Kimpton. No Article 4 direction is recorded for North Hertfordshire District Council, but Codicote & Kimpton's 3 conservation areas still limit permitted development on those streets.

On stock, Codicote & Kimpton is late-1960s and early-1970s houses (21% of 2,330 homes), Victorian and earlier houses (16%) and 1980s estate houses (10%) — which is why shallow-pitched roofs and integral garages typical of that period's building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building govern what a loft or rear projection can realistically be. North Hertfordshire District Council decided 665 householder applications in the latest published year and granted 95%, with 69% issued inside the eight-week target. That decision record, not a national figure, is what we design to.

The full build-period split for Codicote & Kimpton runs pre-1900 16% (380 homes), 1900-1918 3% (60 homes), 1919-1929 3% (80 homes), 1930-1939 6% (140 homes), 1945-1954 5% (120 homes), 1955-1964 8% (190 homes), 1965-1972 21% (500 homes), 1973-1982 9% (210 homes), 1983-1992 10% (230 homes), 1993-1999 3% (80 homes) and 2000-2008 5% (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.

North Hertfordshire District Council also decides for Arbury, Baldock West, Cadwell, Ermine, Hitchin Priory, Hitchwood, Knebworth and Letchworth Norton, so a decision in Codicote & Kimpton 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 Codicote & Kimpton planning application

Whatever you are building, North Hertfordshire District 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. North Hertfordshire District Council assesses each proposal against North Hertfordshire District 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 Codicote & Kimpton's stock, which runs to late-1960s and early-1970s houses (21% of 2,330 homes), Victorian and earlier houses (16%) and 1980s estate houses (10%), the same scheme is drawn differently to answer the concerns officers raise here. Codicote & Kimpton contains Codicote, Kimpton, Kimpton Bottom conservation areas (Codicote designated 1979), 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 — Codicote, Kimpton and Kimpton Bottom among Codicote & Kimpton's — validation is stricter still, often demanding heritage detail and sometimes additional plans. No Article 4 direction is recorded for North Hertfordshire District Council, but Codicote & Kimpton's 3 conservation areas still limit permitted development on those streets. We confirm the designation before drawing so the pack meets the higher bar first time.
