Larger home extension prior approval in Glen

What the data says about planning in Glen

Harborough District Council granted 92% of the householder planning decisions it made in its latest published year — 5 points above the 87% England-wide householder average. Glen contains Gaulby, Illston on the Hill, Kings Norton conservation areas (Gaulby designated 1994), 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.

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 Harborough District Council needs a full application. In conservation areas such as Gaulby, Illston on the Hill and Kings Norton those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Glen is determined against an 8-week statutory target.

Gaulby (conservation area designated in 1994), Illston on the Hill (conservation area designated in 1994), Kings Norton (conservation area designated in 1994), Burton Overy (civil parish within Glen), Gaulby (civil parish within Glen), Great Glen (civil parish within Glen), Illston on the Hill (civil parish within Glen), King's Norton (civil parish within Glen) and Little Stretton (civil parish within Glen) — these are the Glen pockets our drawings cover most. Heritage designations here include Gaulby, Illston on the Hill and Kings Norton. Harborough District Council weighs each proposal against Harborough District Council's development plan and the design policies it applies to householder applications, where the 2,430 homes here are 16% 1965-1972, 12% pre-1900, 9% 1955-1964, 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 (16% of 2,430 homes), Victorian and earlier houses (12%) and late-1950s and early-1960s houses (9%).

Designations, stock and decisions in Glen

Heritage designation is the single biggest variable in Glen, and it is address-specific: Gaulby (conservation area designated in 1994), Illston on the Hill (conservation area designated in 1994) and Kings Norton (conservation area designated in 1994). Inside those boundaries permitted development is curtailed and Harborough 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, Glen takes in Burton Overy, Gaulby, Great Glen, Illston on the Hill, King's Norton and Little Stretton. No Article 4 direction is recorded for Harborough District Council, but Glen's 3 conservation areas still limit permitted development on those streets.

On stock, Glen is late-1960s and early-1970s houses (16% of 2,430 homes), Victorian and earlier houses (12%) and late-1950s and early-1960s houses (9%) — 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. Harborough District Council decided 439 householder applications in the latest published year and granted 92%, with 51% issued inside the eight-week target. We work from the council's own published record.

The full build-period split for Glen runs pre-1900 12% (290 homes), 1900-1918 2% (50 homes), 1919-1929 1% (30 homes), 1930-1939 1% (30 homes), 1945-1954 4% (90 homes), 1955-1964 9% (230 homes), 1965-1972 16% (400 homes), 1973-1982 8% (190 homes), 1983-1992 8% (190 homes), 1993-1999 5% (110 homes) and 2000-2008 8% (200 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.

Harborough District Council also decides for Billesdon & Tilton, Bosworth, Dunton, Fleckney, Kibworths, Lubenham, Misterton and Nevill, so a decision in Glen 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.

How the prior approval route works in Glen

The ordinary Class A limits stop a single-storey rear extension at 3 metres on an attached house and 4 on a detached one. The larger home extension scheme doubles both, on condition that the council is told first. That notification is not an application for permission — the council cannot refuse on design, materials or policy grounds. It can only consider the effect on the amenity of adjoining premises, and only if a neighbour actually objects during the 21-day consultation.

The other conditions still apply and are strict: single storey only, no higher than 4 metres, eaves no higher than the existing eaves, and no more than half the land around the original house covered. It is not available on designated land, so a house in a conservation area such as Gaulby and Illston on the Hill cannot use it at all. Materials must be similar to the existing house, and the extension must not include a veranda, balcony or raised platform.

Glen is largely late-1960s and early-1970s houses (16% of 2,430 homes), Victorian and earlier houses (12%) and late-1950s and early-1960s houses (9%). Glen contains Gaulby, Illston on the Hill, Kings Norton conservation areas (Gaulby designated 1994), so materials, fenestration and roof form are assessed against the appraisal, which matters here because an objecting neighbour puts amenity squarely in front of a case officer. No Article 4 direction is recorded for Harborough District Council, but Glen's 3 conservation areas still limit permitted development on those streets.
