Side return extension plans in North East Derbyshire

North East Derbyshire planning decisions and design rules

North East Derbyshire District Council granted 93% of the householder planning decisions it made in its latest published year — 6 points above the 87% England-wide householder average. North East Derbyshire contains Amber Mill and Toad Hole, Barlow, Barlow Grange conservation areas (Amber Mill and Toad Hole designated 1990), 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 Amber Mill and Toad Hole, Barlow and Barlow Grange those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in North East Derbyshire is determined against an 8-week statutory target.

Amber Mill and Toad Hole (conservation area designated in 1990), Barlow (conservation area designated in 1979), Barlow Grange (conservation area designated in 1990), Barlow Mills and Crow Holes (conservation area designated in 1990), Barlow Woodseats and Johnnygate (conservation area designated in 1990), Cartledge (conservation area designated in 1990), Clay Cross (conservation area designated in 2010), Coal Aston (conservation area designated in 1983), Barlow & Holmesfield (ward of North East Derbyshire), Brampton & Walton (ward of North East Derbyshire), Clay Cross North (ward of North East Derbyshire), Coal Aston (ward of North East Derbyshire), Holmewood & Heath (ward of North East Derbyshire), Pilsley & Morton (ward of North East Derbyshire), Ridgeway & Marsh Lane (ward of North East Derbyshire) and Shirland (ward of North East Derbyshire) — these are the North East Derbyshire pockets our drawings cover most. Heritage designations here include Amber Mill and Toad Hole, Barlow, Barlow Grange, Barlow Mills and Crow Holes, Barlow Woodseats and Johnnygate, Cartledge, Clay Cross and Coal Aston. North East Derbyshire District Council weighs each proposal against North East Derbyshire District Council's development plan and the design policies it applies to householder applications, where the 19,260 homes here are 14% pre-1900, 12% 1955-1964, 11% 1945-1954, 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 (14% of 19,260 homes), late-1950s and early-1960s houses (12%) and early postwar houses (11%).

Why a North East Derbyshire scheme is judged on North East Derbyshire terms

What is permitted in North East Derbyshire turns on designation first, so that is where we start: Amber Mill and Toad Hole (conservation area designated in 1990), Barlow (conservation area designated in 1979), Barlow Grange (conservation area designated in 1990), Barlow Mills and Crow Holes (conservation area designated in 1990), Barlow Woodseats and Johnnygate (conservation area designated in 1990), Cartledge (conservation area designated in 1990), Clay Cross (conservation area designated in 2010) and Coal Aston (conservation area designated in 1983). Inside those boundaries permitted development is curtailed and North East Derbyshire 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, North East Derbyshire takes in Barlow & Holmesfield, Brampton & Walton, Clay Cross North, Coal Aston, Holmewood & Heath, Pilsley & Morton, Ridgeway & Marsh Lane and Shirland. No Article 4 direction is recorded for North East Derbyshire District Council, but the district's 8 conservation areas still limit permitted development on those streets.

On stock, North East Derbyshire is Victorian and earlier houses (14% of 19,260 homes), late-1950s and early-1960s houses (12%) and early postwar houses (11%) — 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. North East Derbyshire District Council decided 304 householder applications in the latest published year and granted 93%, with 62% issued inside the eight-week target. We draw to that record rather than to a national average.

The full build-period split for North East Derbyshire 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.

North East Derbyshire District Council also decides for Barlow & Holmesfield, Brampton & Walton, Clay Cross North, Coal Aston, Holmewood & Heath, Pilsley & Morton, Ridgeway & Marsh Lane and Shirland, so a decision in North East Derbyshire 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.

Side returns drawn for North East Derbyshire's period terraces

The side return is the classic terrace fix, and North East Derbyshire has the stock for it — the borough is built largely from Victorian and earlier houses (14% of 19,260 homes), late-1950s and early-1960s houses (12%) and early postwar houses (11%), and the Victorian and Edwardian versions almost all have an L-shaped back addition with a wasted alley beside it. Fill that alley and the dark galley kitchen becomes a bright, square room the full width of the house. North East Derbyshire District Council judges the infill against North East Derbyshire District Council's development plan and the design policies it applies to householder applications, and because it runs along the party boundary, the neighbour relationship is read before the design.

That boundary is where the drawings earn their keep. We set the infill wall on or up to the line, keep the roof — usually a glazed lantern or a shallow pitch tying into the existing back-addition slope — below the neighbour's first-floor windows, and detail the rainwater and party-wall junction so the build is watertight and the Party Wall Act is satisfied. North East Derbyshire contains Amber Mill and Toad Hole, Barlow, Barlow Grange conservation areas (Amber Mill and Toad Hole designated 1990), so materials, fenestration and roof form are assessed against the appraisal, so we resolve it on the section rather than leave it to the case officer.

Many of North East Derbyshire's terraces sit in conservation areas — Amber Mill and Toad Hole, Barlow, Barlow Grange, Barlow Mills and Crow Holes, Barlow Woodseats and Johnnygate, Cartledge, Clay Cross and Coal Aston among them — where a side extension is no longer permitted development. No Article 4 direction is recorded for North East Derbyshire District Council, but the district's 8 conservation areas still limit permitted development on those streets. We confirm the designation before a line is drawn.
